from seed to weed

Starting from seed is a remarkable journey. Understanding the biology is one thing, but comprehending how a little miracle bean can turn into a gigantic tree that can affect your body and mind is nothing short of an evolutionary miracle. Or rather a co-evolutionary story of plant and human.

When is the ideal time for transplanting seedlings?

“Don’t judge each day by the harvest you reap but by the seeds that you plant.”

What are some of the best practices for planting marijuana seeds?

Seedlings require a medium amount of light in which it has enough to grow but not too much light that it gets burned. Leaving your seedling in direct sunlight will cause the leaves to curl, while too little light will cause the seedling to stretch. If growing outside, seedlings want to see a direct light source to stop them stretching. If inside, a sunny windowsill with more than half a day of sunlight works wonders. Otherwise, 18 in away from a growing light works excellently. Your seedling should not stretch more than 6 in at most. We’ll cover lighting in more depth in a later blog.

The first set of leaves to come above ground are called the cotyledons. These little leaves are packed with energy and will grow to about 1/4 in in size before eventually falling off. Your second leaves to emerge will be single blades and look like regular pot leaves.

Harvesting and drying your buds can be done in various ways as well. You can let the buds dry first and trim them later, but some prefer to do it the other way around. In that case, branches loaded with buds are hung upside-down in the tent to dry before trimming. The downside is that your precious trichomes dry out, making them brittle and easy to lose while trimming.

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.

Germinated and planted: your grow is good to go!

Can I Trim Yet?

When growers receive their Cannabis seeds, it is time to germinate. Germination is the first step of the real growing adventure: so far, everything was just preparation. Once a cannabis seed germinates, its protective shell cracks open, and the first tiny root peeps out. For the sentimental grower, this is an emotional moment – a bit like childbirth, actually. It’s also a moment, however, to be very delicate in handling cannabis seeds.

After drying, I carefully remove all the buds from the nets and place them in glass mason jars to cure. The buds cure gradually, improving their taste and ‘maturing’ them until they are perfect for smoking. Curing buds is a straightforward affair: simply stick them in a jar and wait. Give them time to ‘burp’, though: open them for a few minutes to refresh the air inside and return them to their dark storage location. How long you cure is matter of personal taste. I personally cure my weed for one month before that sweet day arrives: time to smoke those fabulous Amsterdam Genetics! Let’s not kid ourselves here: this is what we’ve been working so hard for, isn’t it?

A small, cheap USB pocket microscope or a jeweler’s lens are great for determining trichome maturity. Clear transparent trichomes are a sign to wait some more. Once they turn milky white, with a few amber-coloured trichomes among them, you’re ready to cut the flowers. Harvest time is finally here!

My biggest mistake ever was leaving the lights on after flowering in the room where I set up my tent. Sadly, the tent wasn’t light-proof, so my plants got stressed out and turned into hermaphrodites. The result: a whole harvest full of seeds that was no use at all… Fourteen weeks of work down the drain! I also made the mistake of pumping out my entire 60L nutrient mix tank in one go once. Pretty bad for plants capable of handling 10 litres at once max…
