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).
If growing male and female cannabis seeds, they’ll start to show their sex organs, or “pre-flowers,” after 8-10 weeks from germination.
Go easy on nutrients
In some cases, even if a seed isn’t completely mature, there’s still a chance it could be viable. But often these are extremely weak, take long to develop, and express other unfavorable characteristics. Growers usually discard weak plants to free up space.
Autoflowers don’t need lots of nutrients because they’re small and don’t spend much time in the vegetative cycle. They won’t need as much veg nutrients—such as nitrogen—but will need more bloom nutrients.
If buying from a reputable breeder or seed bank, growing from seed is the best way to ensure your plants will have solid genetics and start clean, meaning they won’t come with diseases or pests.
STRAIGHT INTO THE MEDIUM: Place seeds directly into your medium, this way you can avoid any transplant shock. More often it is easier to germinate in a small pot of your chosen medium then pot on to the garden or bigger pots.
INDOORS: Lights are set to an eighteen hour day, six hour night light regimen. This doesn’t have to coordinate with the actual daylight hours, you can set it to times of day that suit you. Running electrical equipment during off-peak periods can save you a lot of money.
LIGHTS FOR EVERY BUDGET: At the other end of the scale, you can have a rudimentary yet very efficient CFL (Compact Fluorescent Light) or small LED panel (Light Emitting Diode) setup for less than three hundred dollars. Growing great buds in a spare cupboard. Other compact fluorescent lights like T5 battens come in a range of spectrums for vegging and flowering and can fit in a small space well.
Step 4: Germination And Cannabis Seedlings
Growing your own cannabis is a fun and inexpensive way to put high-quality buds in your jar. Marijuana is a hardy plant that can grow in a wide range of climates, in greenhouses or indoors all year round.
With your personal taste in mind now consider your growing circumstances. Are you growing in a small cupboard where small fast-maturing plants like autoflowering strains or indicas will be the most effective use of your space? Or do you have a nice big backyard where you can grow one or more monsters directly in the soil or in large pots?
HUMIDITY: Outdoors you don’t really have any control over this factor and you are at the mercy of your climate. The upside is that the variations in humidity and the robust biological functions needed to adapt to a changing grow environment makes your plants exceptionally strong!
When your plants have broken the surface and the cotyledons have shed the seed husk and opened to reveal the first set of true leaves photosynthesis has begun. Now you have a true marijuana seedling on its way to becoming a heavy resinous indoor miniature or booming outdoor tree.
