So here’s how to germinate cannabis seeds with the best-known methods and a couple of tips that will get you harvesting in no time.
So when germinating autoflowers you should keep the temperature between 21-26°C and the humidity as close as 90% as you can.
1. First Things First: Know the anatomy of your cannabis seed
Peat pellets are similar to the Rockwool cubes but are made of compressed peat moss and come in a small disc shape.
With a softened shell, it will be easier for the radicle to come out and this is when you’ll see the white taproot slowly appearing, and once it reaches 2-3cm, it’s time to plant it.
If you are storing seeds for your next grow cycle, you need to keep them in ideal conditions.
Planting autoflowering cannabis seeds is a relatively easy process, but to get the most out of your plants you need to follow a series of steps that are completely different from those that seasonal seeds have. An autoflowering cannabis seed needs a bit more care than normal seeds. You need to speed up the growth as much as possible so you don’t get teeny plants with no more than 5 blunts on them. We’re going to give you a series of things you’ll need to do in order to get the most out of your plants.
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.
Germinating Autoflowering Cannabis Seeds:
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.
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.
Now is when you’ll need to transplant your autoflowering plants to their permanent home. Autoflowering strains that take two months prefer pots that are about 7L, whereas those that take three months much prefer pots that are 11L, no bigger.
Start by filling pots with a premium-quality soil that has been soaked in water. Many growers also choose to lace the water with a root stimulator. Make a hole roughly 10–15mm deep. This will be your seed’s new home. Remove the seeds from their packet and place them into the pre-dug holes. Loosely cover the seeds, but be careful not to compress the soil above the seed too much. The root will struggle to penetrate solid soil, slowing plant growth. Lightly spray the top of where you placed the seed so that your growing medium stays moist.
Probably one of the most common methods of germination. The kitchen towel method comes in several iterations. Some growers use cotton wool pads or absorbent pieces of paper. For this guide, we will be using kitchen towel as it is readily available and holds moisture relatively well.
Your growing pots will need to be placed in a damp climate that is within the temperature range listed under our golden rules. After 4–10 days, you should see a young seedling sprout, while the roots will have begun to develop underneath the soil. The entire plant and its soil can now be transferred to a larger pot, where normal growing routines should start.
GLASS OF WATER APPROACH
If you don’t like the idea of pre-soaking your soil, you can use a spray to moisten the holes before you plant each seed. With enough moisture surrounding your seeds, you can still encourage a root to develop.
• The ideal temperature is between 22° and 25°C (71–77°F)
• Your growing environment should be damp/moist, but never wet
• Relative humidity range should be between 70% and 90%
• Seeds favour fluorescent lighting (Cool White code 33)
• Minimise the amount of seed handling you do
• In hydroponic/rockwool plugs, the ideal PH value is 5.8–6.2
The dome of the plastic container will create your seeds’ own mini tropical climate. If you then place all the components in a temperature-controlled cupboard, you will have created a self-perpetuating supply of moisture—no need to touch the seeds again until they are ready to be transferred to your final growing medium as a young seedling. Using the stone wool block method, your seeds should germinate in one to two days.
