I don’t know if I am in the right section but anyways Is anyone here has a piece of knowledge or experience about Germinating marijuana seeds? A new way of germination and growing cannabis vines move seeds in the air and space to grow it and in a vented container swing the container in a different direction. I also grow faster and produce more (OVERNIGHT GROWTH). Will work for other products spray the air with the moisture ingredients (water flavored sugar) and aerated container in moist ingredients environment. Counterclockwise and clockwise thermodynamics wishy-washy field motion is what a sphere with a cylinder in the middle to hold the seed it does hold in all ways. Like a ceiling fan motor or plastic bag. As I do some research, I have read an article about germinating blimburnseeds.com/news/marijuana/legalization/to-regulate-is-to-be-responsible/attachment/jorge-drexler-2/
Introduction: Cannabis Seed Germination
Cannabis germination is the process of getting your seeds to sprout, and you know sprouting has occurred when a little white tendril pops out of the seed.
The little white tendril that emerges from a cannabis seed during germination is your plant's first root, known as a "taproot." All other roots made by your cannabis plant in its lifetime will sprout from the taproot.
The taproot - and maybe a few tiny early offshoots of the taproot - will get longer and longer, pushing the seed up, and after the shell breaks through the surface of your growing medium, the first leaves (these first round leaves are known as "cotyledons") will emerge from inside the cannabis seed. The cotyledons were already created as part of the plant embryo in the seed itself. In fact, the first leaves emerging are what break apart the shell after it's cracked open by the taproot, as pictured here.
The next set of leaves after the cotyledons are your plants first "true" leaves and will have jagged edges (serrations). At least, they are the first leaves that your seedling cannabis plant has grown all on its own, unlike the cotyledons which were already formed in the seed.
Cannabis seeds can be expensive, don't waste your seeds with bad germination methods!
What Do Marijuana Seeds Need to Germinate?
Marijuana seeds need the following to get the best germination rates:
When germinating cannabis seeds, think springtime conditions. In the wild, your cannabis seeds would germinate in the spring so they can be ready to take full advantage of longer summer days!
Never let your young sprouted seeds dry up!
The main signal that tells a marijuana seed to start sprouting is the presence of moisture and heat. The combination of warm and wet (aka spring conditions) "tells" the seed to start burrowing their main root (called a taproot) through their shell.
If a seed's root breaks through the shell and the water around has dried up, your seedling will die. Plain and simple.
Seedlings are fragile at first. Once sprouted, the roots need to stay constantly moist to stay happy and healthy. It's important to make sure the seeds have access to water the entire time during germination, no matter which cannabis germination method you end up using.
Keep things warm!
Seeds germinate best in warmer temperatures and young marijuana seedlings do better with higher relative humidity in the air. When seedlings are young, they grow faster and healthier when they can absorb moisture from the air through their leaves while their roots are still developing. Dry air won't kill your seedlings, but it doesn't make things better. Again, think springtime conditions!
You can use an incandescent bulb (or two) placed over the marijuana seed germination area to help keep things warm. Incandescent bulbs are the opposite of what a grower typically wants: they can't be used as grow lights, but they're great at generating heat. Some people will also place a heating pad (the kind you get from a garden store for seedlings) underneath seeds to help aid germination.
Basically you want to make sure any seeds or sprouts are kept warm and moist at all times, that their roots are unexposed to light, and that they get planted right away.
There are several different methods to germinate your cannabis seeds, and in this article we'll go through some easy techniques that have proven to be effective.
How do I know if my seeds are good?
Assume all dark seeds are viable, even if seeds can be crushed
Generally, pale-green or white seeds will not germinate, but most dark seeds will germinate when given good conditions.
I used to believe that marijuana seeds were only "good" if they were extremely hard and very dark. One of the first tests I heard to check new cannabis seeds for viability was to try to crush them between my fingers. If the seeds could be crushed, they weren't good, or so I was told. This has proven to be absolutely terrible advice!
Some of the best plants I have ever grown have emerged from seeds which were flimsy and could be crushed between my fingers. As long as you provide great marijuana germination conditions (as explained above), I've found that a lot of seemingly "weak" seeds germinate and produce amazingly hardy plants and great buds.
I do not believe the health of the plant is directly tied to the apparent "health" of the seed. If the seed germinates, it's a good seed!
Here's a picture showing several healthy and viable cannabis seeds
Remember! Most of the medical strains of marijuana we grow today. have been bred over many years to produce plants that are easy to grow and which produce potent, medicinal buds. However, these strains have not been selected for the toughness of the seeds they produce since that isn't important to us as growers. Just remember...
As long as a seed germinates, it's a good seed!
Germination Method 1: Starter Cubes & Seedling Plugs (Recommended)
One of the best cannabis germination methods is to use specifically-made starter cubes and seedling plugs. These plugs make cannabis germination easy. You simply place the seed in the cube or plug, add water as directed, and seedlings automatically get the perfect conditions for germination.
Each cube or plug already has a hole specifically for you to place your seed. Just stick your seed into the precut hole and pinch the top closed a bit with your fingers. Don't worry, you can't mess this part up :) As long as the seed makes it in there, you should be good.
This is one of the easiest germination methods, and doesn't leave a lot of room for error. Cannabis seeds and clones can be expensive, and sometimes we have genetics we just can't afford to lose. When that's the case, germinate your cannabis with one of the following recommended options to ensure as close to 100% germination rate as possible.
Which Starter Cubes Work Best for Germinating Cannabis?
Rapid Rooters (Highly Recommended For All Setups)
Rapid Rooters are easy to work with - you just stick your cannabis seed in the Rapid Rooter (pointy side down), keep your seed warm and slightly moist, and let the Rapid Rooter do its magic.
Sprouts emerge and roots appear in just a few days.
Rapid rooter starter cubes are suitable for all growing methods, including hydroponics, coco coir and soil. They work for every setup and come from General Hydroponics, a trusted company (the same one used by NASA) which is known for the quality and consistency of its products.
I highly recommend using Rapid Rooters over any other starter plugs. They are less prone to problems and work great with any growing medium (including hydroponic systems).
Pros of Rapid Rooters
Cons of Rapid Rooters
There are a few different options for Rapid Rooters, which can be confusing if you're not sure what you want. The 3 different options for Rapid Rooters are listed here...
Bag of Rapid Rooters
These are round on bottom instead of being a cube, which means they cannot stand up on their own. These are best suited to a hydroponic setup where the Rapid Rooter will be placed directly in the final destination. In our hydroponic setups, we've had near 100% germination rates with Rapid Rooters, better than any other seedling cube we've tried.
Rapid Rooters Mat
This type of Rapid Rooters comes in a mat of (usually 98) Rapid Rooters. All the individual Rapid Rooters are sectioned off and have a hole for the seed, but they must be cut or pulled away from the complete mat. Unlike the type of Rapid Rooters that comes in a bag, these ones are made into cubes, and are flat on bottom so they can stand alone. This makes them good for germinating in a shallow pool of water where the cubes need to be able to stand up on their own.
Rapid Rooters Tray
The Rapid Rooters tray is perfect for seeds or clones. Allow your young plants to sit in the tray with water until their roots are well formed and ready to be transplanted to your final destination. The standard size tray fits most humidity domes. You can refill the tray with Rapid Rooters from the bag or mat.
As you can see in the pictures below, the Rapid Rooter Tray comes packaged up. Once you open the package, you will see 50 Rapid Rooters already set in the tray. The resing place for each Rapid Rooter has a hole on the bottom so water within the tray is wicked up. The top part comes apart from the bottom.
Just add you seeds and pour some water into the tray - the Rapid Rooters will do everything else for you.
Rockwool Cubes (Not Recommended)
It's often hydroponic growers who use rockwool cubes since these can be safely placed in hydroponic setups, hold a lot of moisture, and are resistant to mold. Rockwool is cheap and easy to find. It comes in convenient cubes. But it does have some major drawbacks...
Pros of Rockwool
Cons of Rockwool
Rockwool cubes are bad for the environment
Rockwool is not a natural material - it's made by heating rock and chalk to 3,000°F and air is blown through the mixture to create thin fibers of rocky material
It does not break down naturally and therefore after rockwool is created, it will remain in that form basically forever, filling up landfills without breaking down for thousands of years.
Rockwool cubes can be bad for your health
Rockwool is dusty and needs to be rinsed thoroughly before use. Little pieces of rockwool and dust can easily get in your eyes, skin and mouth. Small strands or fibers can get lodged in your lungs if you breath in rockwool dust, and it's unknown if these fibers can ever get out again.
Protect yourself! Always use a mask, goggles and gloves when working with rockwool.
Rockwool cubes have a high pH until they're treated
New rockwool cubes have a high pH - too high for healthy cannabis seed germination. Therefore it's important to thoroughly rinse rockwool cubes in pHed water, then let them soak in pHed water overnight before use. Since rockwool holds onto a lot of water, after soaking they should be given a few days to dry out before planting seeds or making clones.
Rockwool cubes do not get great germination rates
Rockwool can be difficult to germinate marijuana seeds in, so I recommend most beginner growers sprout their seeds using another method like Rapid Rooters (mentioned above) which can also be used in hydropnic applications but are less prone to germination problems.
Many growers have placed seeds in rockwool cubes, only to wait for weeks and never see seedlings appear.
Some growers seem to have no problems, yet many other growers suffer through very poor germination rates. Some seed companies will not honor seed germination guarantees if the grower uses rockwool, because it is notoriously bad for germination.
Learn more about the pros and cons of rockwool
If you do use rockwool, it's recommended you germinate your seeds using another method like the paper towel method, then transplant your seeds to the rockwool cubes after roots have already appeared.
Even when following all the best practices, we just have not gotten great germination rates with rockwool cubes, and it's common for new seedlings not to make it. When we were using rockwool (before we switched to Rapid Rooters), we usually lost at least 1 seed out of batch of 6 or 8.
We also had trouble rooting clones in rockwool. Rockwool cubes just don't hold enough air to get plenty of oxygen to the roots, and they tend to hold onto a lot of water and get waterlogged easily. Since rockwool can hold a lot of water, it's prone to "drowning" seeds
I highly recommend using Rapid Rooters instead for your hydroponic application (or any grow setup), as they are much more user-friendly and tend to get far better germination rates.
Jiffy Pellets (Recommended for Soil or Coco Coir)
Jiffy Pellets are used in a similar way to rockwool cubes, though these tend to get much better germination results. Jiffy pellets are not suitable for most hydroponic setups where the roots are grown directly in water, but Jiffy Pellets can be directly transferred into soil or coco coir.
Pros of Jiffy Pellets
Cons of Jiffy Pellets
How to Use: Soak Jiffy pellets in warm water, which makes the pellets expand in size, as pictured below.
Once the compressed Jiffy pellets have expanded in warm water, gently squeeze excess water from each pellet and you're ready to go. Treat them the same as Rapid Rooters.
Germination Method 2: Plant marijuana seeds directly in growing medium
Sometimes nature's way is the easiest way. In nature, marijuana seedlings would sprout in soil, and they would emerge as their taproots start growing down.
As a grower, you can also plant your seeds directly in your final growing medium. This works in all growing mediums, though some can be tougher than others.
One of the biggest benefits of planting your seed directly in the growing medium is you don't have to worry about shocking your young seedling during transplant. Because your seed is already in its final resting place, your new seedling will immediately start adjusting to the environment. Every time you transplant a sprouted seed, it can cause stress as the young plant needs to readjust its new surroundings.
Germination Method 3: Germination Station
One option for growers is to use a tool which has been specifically designed to provide optimal germination conditions like this germination station with heat mat.
You can make a DIY germination station at home by putting a plastic dome over a plate on a heating pad.
There are benefits to the professionally made germination stations as they work very well and are pretty cheap to buy.
One of the advantages of starting seeds in starter cubes is your sprouted seeds can easily be transferred right to their next growing medium or container.
I recommend Rapid Rooters as these starter cubes work great for cannabis seeds and can be used in any growing medium including hydroponics, soil, or coco coir. Other starter cubes include Jiffy Peat Pellets, and Rockwool cubes.
Once your seed has sprouted, just make a little hole in your growing medium, and place the entire pellet inside. Make sure growing medium is also moist yet not soaking, like your pellet or cube. The roots will emerge from the bottom of the cube and burrow directly into your growing medium.
Germination Method 4: Soak Marijuana Seeds in Water Overnight
Another method to germinate marijuana seeds is to soak them overnight in slightly warm water, usually done in a glass drinking cup.
This method is especially effective for seeds which have extra hard shells, or seeds which are older (more than a few years old).
The warm overnight soaking can help "wake up" older seeds.
Most viable seeds will start out floating, and then eventually sink to the bottom of your glass after a few hours of soaking.
If soaked in a clear drinking glass, you will see when the little white tap root first breaks through the shell.
Some seeds take longer than others to sprout. Especially older seeds tend to need longer to pierce through their shell. However, if seeds are left soaking too long, and haven't yet sprouted, they can drown.
Therefore, do not leave seeds soaking in water for more than 24-32 hours.
After 24 hours, I recommend putting any still-ungerminated seeds in a warm, moist place to finish germinating.
Germination Method 5: Paper Plate Method
One way to germinate seeds is to wet a paper towel and then fold your seeds in it, then leave the paper towel in a warm place.
If you germinate your seeds in a paper towel, there is the risk of hurting the tap root (the little white root that grows out of your seeds) when moving the sprouted seeds so make sure you are careful when you're checking to see if the seeds sprouted.
There is also the possibility of having the towel dry out which will kill your new seeds so I recommend putting your paper towel under an upside down bowl or between two paper plates.
Check on germinating seeds once every 12 hours or so (make sure not to disturb them or their roots) and plant any seeds which have sprouted right away.
How to Plant Your Germinated Cannabis Seeds
After you see that your cannabis seeds have sprouted, you should plant them right away.
You don't want to touch the little white taproot with your fingers, so either carefully move the seeds, or use twissors. If you do touch or break the root, the seedling may still survive, but any damage to the root will definitely stunt and slow down growth right in the beginning.
Root down! Plant seeds so that the white root faces downward, about a knuckle deep.
The top of the seed should be just below the surface of your growing medium.
It can take anywhere from a couple of hours to a couple of days before you see the young seedling emerge from the soil or growing medium. If your marijuana seedling hasn't sprouted from the soil within 10 days after being placed root-down, it probably died. I'm sorry. Even with the best practices and the best seeds, you will occasionally lose a seed.
Within that 10-day period, you will notice that some seeds germinate right away and others take a little bit longer. The amount of time does not really have anything to do with how healthy your plant will be in the long run. It usually has more to do with the placement of the seed and where its root sprouted.
Avoid letting light touch the roots! Light can be dangerous to young marijuana roots. In fact your seedlings can't even use light until they develop their first set of leaves, called the cotyledons. Until then they are powering themselves based just on the energy and nutrients that were contained in the seed.
Before seedlings get their first leaves, you only want to use your lights as a heating source to maintain a warm environment. The actual light will not help young seedlings grow faster until they've developed their first set of leaves.
If you will be transplanting your seedlings again, avoid transplanting until they are well established and have a couple of sets of leaves (nodes). Some growers will plant seedlings in a growing medium in a solo cup or peat pot, so they can just cut away the cup for easy transplanting.
When you move seedlings around a lot, it stresses them out and potentially stunts their growth. Too much stress can even kill them. So try to plan from the beginning so that you move your seedlings around as little as possible. once they get bigger, they are a lot more hardy and can stand a lot more stress and movement.
Here's some pictures to give you and idea of the timeline to expect
Sprouted seeds planted in Hydrofarm pellets and placed on soil
If you want, you can put bottles on top to help retain extra humidity (like a cheap humidity dome).
It's a steady 85 degrees F in there, no idea about the humidity in the bottles.

Your Cannabis Seedling's First Few Weeks
During the first few weeks of a young marijuana plant's life, you have to be careful.
Marijuana seedlings, especially seeds from some of the most potent strains, tend to be a bit delicate.
Seedlings definitely won't be able to withstand full-strength grow lights or nutrients. They need to have a moist environment, but also can easily be drowned or overwatered.
If you're planting in soil, start with a balanced potting soil that doesn't contain extra nutrients. I recommend Happy Frog potting soil mix for young cannabis seedlings, but any plain potting mix from your local garden store will do. Never use Miracle-Gro soil or any soil that has "time-released" nutrients already mixed in. After your plants have grown a few sets of leaves, you can transfer them to a stronger potting mix that contains higher levels of nutrients like Fox Farms Ocean Forest soil, or you can start supplementing with cannabis soil nutrients. Don't want to use nutrients? Learn how to mix up your own super soil so it has all the nutrients your cannabis plants will need!
If you're planting in coco coir, a soilless medium, or hydroponics, only add cannabis nutrients at seedling strength, or 1/4 the regular strength, until your plants have grown a few sets of leaves. Then you can slowly start working your way up to full strength nutrient levels.
With young marijuana seedlings, less is more.
You're trying to give young plants a very small dose of nutrients at first. However, even with young marijuana seedlings, the pH of your water and growing medium is important. Some growers get lucky and happen to have water with the right pH, but if you're noticing deficiencies and problems with your seedlings, definitely take the time to understand about marijuana root pH and how it affects the plant's overall health.
If you plan on eventually putting your marijuana seedlings under high intensity grow lights (such as HPS or MH grow lights), you may want to start them out with less intense flourescent grow lights or compact florescent bulbs (CFLs). Or just keep your high intensity grow lights several feet away at first, and slowly move lights closer as your seedlings gets older
CFL bulbs (twisty/spiral bulbs as pictured to the right) are a great source of light for young marijuana seedlings
Keep CFLs or flourescent lights about 6 inches away from your seedlings. Place your hand where the leaves are to make sure it doesn't feel too hot. If it's hot for your after 10 seconds, it's too hot for your plants.
Once your seedlings have developed their first two sets of leaves, then you can move these lights as close as 2 inches away as long as the lights aren't too hot.
Remember: If grow lights feels too hot to your hand after 10 seconds, they're too hot for your marijuana seedlings
Make sure to keep a close eye on your seedlings to ensure they don't grow too close to the grow lights and burn themselves. Seedlings can grow fast, and many growers have been surprised to find plants have actually grown into the light overnight.
If new seedlings are showing signs of stress, try moving the lights further away and see if that helps.
Once marijuana seedlings are about fourteen days old, they're ready to be start being treated as if they're in the vegetative stage.
This Timeline Will Help Show You What to Expect
Next, the single-finger leaves expand, and the next set is usually 3-finger leaves
Next, the cannabis plant will start making 5-finger leaves
Finally, most cannabis plants stop at 7-finger leaves
If you look closely at the above plant, you can see that some of the newer leaves on this plant actually have 9 fingers. It is normal for there to be some variation between leaves - some plants will grow leaves with 11 or even 13 fingers. But the above guide will give you a general idea of what to expect.
Once your cannabis seedling is about fourteen days old, it's ready to be start being treated as if in the vegetative stage.
Make sure you learn about plant training techniques to make the most of your time in the vegetative stage!
Wait! My seed is growing upside down with the roots up; what do I do?
As long as the roots of a cannabis seedling are able to grow down, they will. Roots never grow upward on their own. Seedlings can sense the difference between up and down. Roots always try to grow down. Roots never grow upwards.
So how come sometimes it looks like a cannabis plant is growing with its roots pointing up?
When the seed end is still bent down, all you see is a U-shaped stem/root
Cannabis seeds can look a bit different when germinating. When in doubt, always wait a few days to see if leaves appear before you try to interfere.
Sometimes the stem of a brand new cannabis seedling can look like the roots growing out the top. But if you wait and watch, you'll see that it's all part of the plan. Hope these pics help someone!
Sometimes you'll see what appears to be roots emerging from your cannabis seed, but this is actually the stem. The stem pushes the seed and leaves up, and the main taproot is currently burrowing down to support the seedling
As the seedling emerges you'll be able to see the leaves (sometimes it will still have the seed stuck on the first leaves, like in the picture above).
The cotyledons (first, round leaves) unfurl, and then the regular cannabis leaves between to grow. Here's another view of that same seedling from above. Even though it may have looked a bit weird at first, this seedling is completely normal and will grow just fine from now on.
What Size Pot Should I Use?
When growing cannabis plants in a container, you have to choose the size of your pot.
A general guide is to have about 2 gallons per 12" of height. This isn't perfect, since plants often grow differently, but this is a good rule of thumb.
When in doubt, get a bigger final container size as opposed to a smaller one. Plants that get rootbound from being in a too-small container will grow more slowly and be prone to problems. It's not good to transfer plants during the flowering/budding stage, so you want to have your cannabis plants in their final container at least 2 weeks before the beginning of flowering/budding. How do I get my cannabis plants to start flowering?
Final Container for Desired Plant Size - General guide
12" ~ 1-2 gallon container
24" ~ 2-4 gallon container
36" ~ 3-6 gallon container
48" ~ 4-8 gallon container
60" ~ 5-10 gallon container
But what size pot should you use for your seedlings?
For fastest growth rates, it's better to plant young seedlings or clones in a very small container, like a disposable plastic solo cup.
For new seedlings and clones, use a small container if possible
The reason you want to start with a small container is that your plant's young roots thrive on oxygen. Cannabis plant roots "breathe" oxygen, just like we breathe air, and it's important that young cannabis roots get plenty of oxygen so the plant can grow as fast as possible.
However, young plant roots do not drink much water yet. When you water seedlings or clones in a very big container, they will use up all the oxygen quickly, and the large size of the container will prevent the growing medium from drying out.
A big plant will drink up all the water quickly, but with seedlings, you're basically waiting for the growing medium to dry out by itself. While you're waiting for the container to dry out, your cannabis roots are sitting in a wet environment and not getting much oxygen, slowing down their growth rates.
Poke holes in the bottom of your cup so water can drain out easily!
By planting young seeds in a small container with holes in the bottom, the growing medium will dry out much more quickly, allowing you to water more often. The young cannabis will get plenty of oxygen and water.
Alternative to Solo Cup: Start plants in seedling cube
If you don't want to have to transplant your young plants, you can start them in a seedling plug or cube and wait until you start seeing roots come out the bottom. At that point, they will be ready to be transferred to a larger container.
What happens if I plant seeds or clones in a big container?
Your cannabis seedlings and clones will definitely survive in a bigger container; they just won't grow as fast for the first few days or weeks because they aren't getting as much oxygen.
With a bigger container, you will need to wait longer between waterings, and during that time your plant roots will be getting reduced oxygen.
If you've planted your young plant in a large container, try to give only a little bit of water at a time (enough to wet the area around the seedling roots) until the plant is growing vigorously. Once the plant has grown a few sets of leaves, you should start watering cannabis normally so that water drains out the bottom.
One of the advantages of starting young plants in a big container is you won't have to transfer them to bigger containers as they get older.
If you start your cannabis plants in a small container, you will need to transfer them to bigger containers so that the roots have plenty of room to expand.
The process of transplanting can shock your cannabis plants, especially if you wait too long to transplant. The way to avoid causing your plants stress during transplant is to transplant after roots have begun to fill container (to help hold all the growing medium together) but before the roots have started wrapping around the edges (plants have become rootbound).
Remember, it is okay to plant your young cannabis in a large container right from the beginning, just know that they'll grow a bit slower for the first week or two.
If you do want to achieve faster growth rates with transplanting, here's a good general guide to make sure you transplant at just the right time, so your plants never get stressed out, and grow as fast as possible.
This grower may have waited just a bit too long before transplanting to bigger container
2.) Place young plants in a solo cup with holes in the bottom to allow water to drain freely.
Allow them to grow a few sets of leaves, like this...
Instead of pulling the whole plant out of the container, it's often easier to just cut away the solo cup when you plan on transplanting. This is one of the advantages of starting in disposable cups - it makes transplanting easy and stress-free.
3.) Transfer plants to a 1, 2 or 3 gallon pot, like this
Plants are ready to transfer again when they have about doubled in height.
They should look something like this...
4.) Transfer cannabis plants into their final container! That's it. You're done with transplanting!
Now you just need to worry about taking care of your plants until you're ready to start flowering/budding. Remember plants will usually double (or even triple) in size from when you first initiate the flowering stage.
