This is the beauty of seeds—often, you can tell which plants or genetics will thrive right from the get-go. This will help you determine which plants you want to take cuttings from for clones or for breeding if you want to create a seed bank of your own.
Cannabis can be either male or female—also called “dioecious”—but only females produce the buds we all know and love. For reproduction, males have pollen sacs and pollinate females, causing female flowers to produce seeds.
As mentioned above, you can skip the processing of sexing weed plants by growing with feminized seeds or clones.
The main drawback to growing from seed is there is no guarantee as to what you’ll end up with—if you buy a regular pack of cannabis seeds, it will be a mix of males and females. You’ll need to sex them out (more below) to identify the males and get rid of them, because you don’t want your females producing seeds.
Take two of the paper towels and place them on a plate. Then, place the marijuana seeds at least an inch apart from each other and cover them with the remaining two water-soaked paper towels.
Cannabis is grown from one of two sources: a seed or a clone. Seeds carry genetic information from two parent plants and can express many different combinations of traits: some from the mother, some from the father, and some traits from both.
Additionally, every long-time grower will tell you that clones degrade over time.
Sea Of Green (SOG) allows you to grow more plants per square metre. You switch to 12/12 lighting early, creating a ‘sea’ of flowering buds.
LST, or low-stress training, simply amounts to bending and fixating your plants. This ensures maximum grow surface spread and enough light for optimal flowering across all branches.
Germinated and planted: your grow is good to go!
Don’t Wake The Neighbours
The flowering phase is where the actual magic happens. At this point, your home grow will start developing the (flower) buds containing the THC, CBD and other useful compounds. You can initiate the flowering stage by making your plants believe the calendar has moved past its midsummer peak. How, you wonder? Easy: just make the days shorter! Grab your timer and change the lighting settings from 18 hours of light and 6 hours of darkness to 12 hours of light/ 12 hours of dark. There you go; you’ve just started late summer in your tent! After about 8 to 12 days, you’ll see the first flowering hairs or pistils emerge. That’s a good sign: your plants have started flowering.
The next step is transferring them to the full-sized grow tent. Time to repot ad\gain: choose a flower pot that matches your approach and available space. In my case, that’s 18 litres.
Personally, I prefer the following high success rate germination procedure. I take a glass of lukewarm water and gently chuck in the seeds. Then, I leave them alone someplace dark for 12 to 24 hours. I check them regularly: as soon as I see white tips (taproots) emerge, I carefully pick up the seed with a pincer. I place them root-down into a pre-watered grow plug. I use a water and root stimulator mix following user instructions. Then I put the plug and seed in my propagator and patiently wait for them to surface.
