Seeds can also form in plants with genetic disorders or instability, like hermaphrodites—plants that develop both male and female reproductive parts. Generally, stress and genetic disorders are viewed as bad, so temper expectations with any plant you start from a bagseed.
Feminized cannabis seeds will produce only female plants for getting buds, so there is no need to remove males or worry about female plants getting pollinated. Feminized seeds are produced by causing the monoecious condition in a female cannabis plant—the resulting seeds are nearly identical to the self-pollinated female parent, as only one set of genes is present.
If you’re ready for a more serious approach, make sure you have the space for a proper garden and pop the seeds to see what fruit they bear.
Is a bagseed good or bad?
Seeds found in finished cannabis buds can develop for a number of reasons. For example, a male plant may have accidentally pollinated a flowering female during the growing process. But more commonly, they’re a sign of stress and can be attributed to high temperatures during the final stages of flowering or an exaggerated spike in climate or environment.
Even if your seed sprouts fast and grows vigorously, it still has roughly a 50/50 chance of being female and producing buds, instead of turning out to be a male.
Immature seeds tend to be light in color and have a soft outer shell.
You might also find a mature seed that has been physically damaged through poor handling, like rough trimming. In those cases, it probably isn’t worth the effort to try and germinate the seed.
Seedlings intended for outdoors should be acclimatised to direct sunlight by placing them on a windowsill inside the house and increasing their exposure to direct sunlight by an hour or two per day.
Cannabis seedlings usually emerge from the growing medium 24 to 72 hours after the germinated seeds are planted.
Lastly, cover everything with the second plate, upside down, to form a ‘clam-shell’ shape – this will create the dark, moist environment necessary for germination.
Step 3. Potting – How to germinate cannabis seeds
Within a few days some or all of the seeds should open and put out a root. It is common for cannabis seeds to open within 72 hours of being put in the germination medium. Less commonly, some seeds may need up to 10 days or even two weeks to open and put out a root.
Unfortunately, regulation and implementation in respect of cannabis seeds often differ from country to country. For this reason we advise you as a matter of urgency to make inquiries about the regulations to which you are subject. Read the complete disclaimer here.
Place the cannabis seed, root first, into the hole and cover with a small amount of growing medium – just enough to block light, not enough to obstruct the seedling when it emerges.
Line the bottom of the first plate with a few layers of wet tissue and drain any excess water from the plate.
Place the seed inside the hole and cover it up. Then, you can add some water. The packaging should have instructions on how much water to add. The weed seeds can take anywhere from two to five days to finish germinating.
Each cannabis seed is different. Some plants will finish their germination stage quickly, and others will take some time to sprout. On average, you can expect germination to last two to four days. Some growers end up waiting 48 to 72 hours. In some cases, a seed may take seven days to germinate. You usually do not need to wait longer than 10 days.
At first, the seeds will float, but they will sink to the bottom after a few hours. Carefully push them down if they are still floating. You can leave the cup in a kitchen cabinet or dark area. Keep the glass there overnight or for 18 to 36 hours. Try not to leave them soaking for more than 36 hours. If there are any seeds that have not finished germinating, leave them in a moist place until they sprout.
Best way to germinate cannabis seeds
There is more than one way to germinate weed seeds. Each one comes with its benefits and disadvantages for growers. Common methods are:
Now that you know how to germinate cannabis seeds, the next step is to plant the sprouted seedlings. You do not need much in terms of planting. For example, you will want a large enough pot and a plant sprayer. If you used incandescent bulbs to keep the seeds warm, switch them out for actual growing lights.
Next, place the cubes into the bowl and let them soak for one hour. After an hour, take the Rockwool out. They can maintain the correct water-to-air ratio, so it is important not to squeeze the cubes. Like regular starter cubes, Rockwool usually comes with holes already in them. If not, make one that is a quarter-inch deep. Carefully insert a seed and push them to the bottom. Cover the top of the hole and wait. The seedlings finish germination in an average of three days.
The early development stage requires things like warmth and a gentle touch. You can approach germination in multiple ways. A couple of them are better than others. This article will provide you tips and other helpful information on how to germinate weed seeds. Soon, you will have many healthy cannabis plants growing.
