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.
Take four sheets of paper towels and soak them with distilled water. The towels should be soaked but shouldn’t have excess water running off.
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).
Is the seed viable?
Cannabis used for hemp production has been selected for other traits, including a low THC content, so as to comply with the 2018 Farm Bill. Consequently, many varieties of hemp produce significant quantities of CBD.
Within a week or so you should see a seedling begin to grow from the soil.
Growing marijuana takes a certain level of commitment: time, energy, and financial resources, so be sure you can commit to the whole process.
For a seed to be viable, it must be mature enough to have a completely formed genetic blueprint, and it must be strong enough to germinate and pop through its hard casing and sprout its crucial taproot.
Finish things off by spraying the surface with a plant sprayer to make the soil moist. Seeds need to remain moist, so you should frequently check the dirt to make sure it has enough water for healthy plant growth.
The best choice of soil for marijuana seeds is a light mix. The light mix does not have a high concentration of nutrients, which can be detrimental to a seedling’s health. Young plants do not need as many nutrients as mature ones.
The dimple should be about a couple of centimeters deep. If you are using a pencil, an easy way to measure is by making the tiny hole erasure-deep. Like any plant, you do not want to plant the weed seed too far in the growing medium.
FAQ About Planting Weed Seeds
Some seeds may be tricky to plant and grow, but you do not need much regarding cannabis seeds. You will notice that many of the tools are already in your home. If you need to get any additional items, you can find them in a regular store or garden center. The list of equipment includes:
Some growers use the damp paper towel method for the germination process. Sometimes, the newly-formed root of the seed can get stuck to the paper towel. The first instinct is to pull it loose carefully, but the action could potentially damage the plant. Instead, spray it with some water to encourage the root to let go of the paper towel.
Burying a weed seed too far into the soil can negatively impact its growth. The recommended depth of the hole is 2 to 2.5 centimeters. It is the best length because seedlings have roots that are 1.5 to 2.5 centimeters long. A couple of centimeters ensures they have enough space.
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.
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.
Arguably one of the least effective methods, but it is still viable. Incredibly simple to facilitate, beginner growers may opt to germinate their seeds in a glass of water. Half-fill a glass or bowl with water that is approximately 22°C (71°F).
You will need to invest in a few pieces of unique equipment, but by using stone wool blocks, you can create a perfect utopia for germinating cannabis seeds. Soak the stone wool blocks in the same way you would a soil medium. The wool will retain the moisture and prevent the need to water during the early stages of germination. After the wool blocks are soaked, stick them in a plastic tray that also has a lid. Large cake tubs are ideal.
WET KITCHEN TOWEL METHOD
Two or three weeks after germination, your young seedlings should be ready for their new home. At this point you have two options; transplanting them into soil pots, or taking on the challenge of hydroponics. You’ll know when the seedlings are ready to be moved because the root system should start to poke out of the bottom of the wool blocks. As long as the roots haven’t begun to engulf the bottom half of the wool block, they will seek out water and nutrients in their new surroundings and continue to grow downwards.
Place one sheet of damp kitchen towel on a flat surface. Space your seeds a few centimetres apart before placing the second piece of kitchen towel over the top. You need to ensure both pieces are damp, not wet. Once again, when the white root tips reach 2–3mm, move the seeds (carefully) to soil pots. Use the same guidance found above for planting techniques.
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.
Before you can be met with bountiful hauls of dank buds, there are several stages of cannabis growing that take precedence. Unless you can successfully germinate cannabis seeds, you won’t have a plant to harvest. Give your seeds the best possible start in life by reading our definitive guide to germination.
