There are multiple things to avoid when you plant weed seeds. Common tips include not fertilizing or adding extra nutrients to the seedling. As mentioned before, the plants can be vulnerable to too high amounts of minerals.
Growers usually germinate cannabis seeds before they plant them. The germination stage is relatively short, and it takes an average of two to three days. Some weed seeds take longer than others due to multiple factors. The technique you used to germinate can influence how long it takes to germinate. For example, the recommended water method lasts roughly 18 to 36 hours for most seeds.
You have finished germinating your weed seeds, and it is now time to begin planting them. Planting weed seeds involves moving a seedling from a paper towel or small container to a larger pot. There are a few items you will need and tips to keep in mind.
How Long to Germinate Weed Seeds Before Planting?
The final step of the planting stage is one of the quickest ones to do. All you need to do is cover the cannabis seed with a thin layer of soil. About a couple of millimeters should do the trick. The thin layer is enough to block out the grow lights or sun while giving the seedling room to grow.
You can lightly pat the soil to ensure that the plant can absorb the moisture correctly. However, try not to press down on it firmly once it is covering the young seedling. If the soil becomes compact, the weed seed might have a hard time getting enough oxygen. Not to mention, there might be a higher chance of disease from poor drainage.
The seed has enough energy to push through a thin layer. The farther down it is, the more likely the soil could hinder the plant’s ability to grow. It might not be able to get the light it needs, and the stem could become weak. If you believe you planted the germinated seed too deep, try brushing away some soil instead of repositioning the plant.
Not to mention, hard seeds may need up to a week to begin sprouting due to a thicker coating. If they have not germinated after two weeks, then they are likely a dud.
As interest in CBD as a medicine has grown, many breeders have crossed high-CBD hemp with cannabis. These strains have little or no THC, 1:1 ratios of THC and CBD, or some have a high-THC content along with significant amounts of CBD (3% or more).
Keep a close eye on the temperature and moisture level of the soil to keep the seed happy. It’s very delicate at this stage. Use a spray bottle to water it—over-watering can suffocate and kill the delicate sprout.
Go easy on nutrients
Most cannabis plants begin flowering when the amount of light they receive on a daily basis reduces. Outdoors, this happens when the sun starts setting earlier in the day as the season turns from summer to autumn. Indoor growers can control when a plant flowers by reducing the daily amount of light plants receive from 18 hours to 12 hours.
There are a few indicators that will give you a sense of whether the seed is worth germinating.
Make sure the area the seeds are in is warm, somewhere between 70-85°F.
You don’t want to touch the little white taproot with your fingers, so either carefully move the seeds, or use tweezers. 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.
Remember! Most of the medical strains of marijuana we grow today (learn how to get seeds) 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…
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
Germination Method 4: Soak Marijuana Seeds in Water Overnight
When growers start their cannabis seedlings in a germination station, the seeds are usually germinated in a starter seedling cube.
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!
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.
After closing a Rapid Rooter, it’s hard to tell it’s been opened. The texture of Rapid Rooters causes the seeds to stay in place and not “fall down” further into the hole once you’ve got it closed.
