Here’s a quick video to help you with germination:
There are various products that can be used on seedlings, but they are not necessary because they will be fine even if they are left alone. At this point, you can use CFLs or fluorescent lights to ensure that the seedlings don’t burn under powerful lights.
We recommend a mix of soil, perlite, and coco fiber to provide enough water drainage and oxygenation, resulting in the best soil for autoflowers.
It’s pretty easy to germinate cannabis seeds. You can sow the seeds directly in the pot, but if you don’t have a lot of experience or are impatient like the rest of us, soak the seeds in plain water for 24 hours. It’s common to see a tiny taproot after a day of soaking but it’s alright if you don’t see them.
Obviously, there are several brands and qualities but most LEDs consume up to 60% of energy and growers say that their plants produce more trichomes, so depending on why you’re growing and if you can afford it, it’s definitely a good choice.
A few years ago LEDs weren’t too good so growers didn’t even think about using them due to the high cost and because they weren’t as good as they’re nowadays.
Light bulbs are essentially found in two types, Metal Halide (MH) and High-Pressure Sodium (HPS), each one of them is used in different stages of plant growth due to the spectrum emitted and the results are quite good.
The next step is watering with growth fertilizers once it’s dry after that first watering. You should be at around day 13 or 14 and you’ll have noticed a bit of growth in the last couple of days. For watering, you should make your mix in a bottle with just one glass of water per pot at this stage. The next day check and see if the pots are heavy; if they’re dry then give them another glass of water but if they’re not don’t water them again until the next day. If the soil is extremely dry the next day then you’ll need to give it two glasses of water. Up the dosage as time goes by little by little and this process of dryness and water will make the plant grow a nice root system, as well as an amazing production.
Before you realize it, it will be day 25 and your plant should be beginning to flower. It no longer looks like the plants you had before, does it? You haven’t changed the seeds, just the method. Now all you have to do is follow the typical flowering steps that every seed needs; a flowering stimulant to begin with, a flowering base, a fattening products once the buds have formed, and end it all by washing out the roots. Flowers take about 20 days to properly form and the fattening period lasts about 2 weeks rather than four weeks for a seasonal seed; once you see the flowers forming properly then you need to use the fattening product.
Up until this point the process has been exactly the same for seasonal seeds, but that’s about to change. You’ll need to wait for the plant to break the surface and have that little growth spurt that cannabis plants tend to get when they’re looking for light. This can take 4 or 5 days, and you’ll need to keep a close eye on them so you don’t leave them for too long. Make sure that the plant doesn’t begin to develop in that flowerpot, the maximum time you should leave the plant in it is 6 days.
Germinating Autoflowering Cannabis Seeds:
I use a liter of water with Canna Terra Professional, and no excess water comes out of the holes in the flowerpot which means it’s adequately watered. You can read all about substrates here.
Bury the seed about half a cm to 1cm down into the soil, making a hole with a pen or a toothpick and putting the seed inside with the little root facing downwards. Cover it with a bit of soil without compacting it too much and leave it there until the plant begins to grow above the soil. What we usually do is leave it for 24h with light during this process until you transplant the seed to its main flowerpot. If you don’t have grow lights then use the most powerful one you can so that it doesn’t get too cold in the pot.
Once your seeds have germinated or opened, however you prefer to call it, you’ll need to prepare some small Teku 7×7 pots with soil, don’t use jiffy pellets or anything like that as the roots need plenty of space to grow.
Fill the pots with soil first and then water them; once the plant breaches the top of the soil you mustn’t wet it again. If you water it before the seed has come out then it will probably move up towards the surface which can cause a whole list of other issues. The best thing to do is to water first and then wait to water it again until the sapling grows a bit.
Have in mind that it’s possible to drown the seed, so we need to keep an eye on moisture levels, also making sure it doesn’t dry out.
As you may have seen, the seed is made out of two halves and has a ridge around it, if your seeds are old, that ridge may end up hardening too much and the seed won’t sprout.
2. The Best Conditions For Germinating Seeds
The cannabis seed has a dark brown, hard, and often striped, shell, this shell is what protects the insides which are extremely fragile.
Just grab a pencil, or even with your fingers, make a little hole (1-2cm deep), and place the seed in it, the medium must be moist but not soaking, then cover with soil without applying pressure.
To germinate in either one of them, we will use the same technique explained before, moisten the Rockwool or peat pellet, make a little hole (1-2cm) and place the seed inside, cover it gently without applying pressure and you’re all done.
