Breaking through the germination stage, plants enter the seedling stage next. At this point, they’ll need about 18 or more hours of daily light. After two or so weeks of proper care, though, they’ll be well on their way to robust growth.
Aside from the buds themselves, another way you can tell your plant is approaching harvest is by examining the colour of the leaves. Provided you haven’t overfed your plants during the final stage of flowering, a yellowing of the leaves will signal that your plant is reaching peak maturity, and that its nutrients are being fully utilised by the buds. By flushing out nutrient salt buildup with pH-balanced water for a couple weeks before harvest, a smoother, more pleasant smoke is guaranteed from each plant.

Even when your plant is a mere seed, the work you put in will dictate its success or failure. Germination is the stage when the first root cracks out of the seed’s shell, which takes between 1–7 days. The wet paper towel method is a classic approach here, but you start out with the major setback of tiny fibres all over your new root. You can plant directly in the soil, of course, but you need to ensure temperature and moisture are dialled in.
Looking for shifts in trichome appearance is the most accurate way to determine the stage of maturity of your crop. Trichomes are hard to miss and appear as a white frosty substance that covers the buds and sugar leaves. Zooming in on these structures will allow you to know how far along your plants are, and whether they are ready for the chop.
Autos really only flower for 30-45 days with a much more sudden transition into flowering, choosing feminised autos is a wise choice for novices that don’t want a seeded stash.
More and more research suggests the great benefits of cannabinoids for human and animal health. Consequently, more areas are legalizing cannabis in some form, and making it possible for individuals and companies to safely cultivate their own cannabis.
Conversely, feminized seeds that yield only female plants. When growing exclusively female plants, there is no risk of pollination which means the female plants can produce more cannabinoids and no seeds. A common term for premium, seedless cannabis is sensimilla.

To perform a float test, simply drop your seed into a glass cup or jar of distilled or spring water and leave it for a few hours. Viable seeds will absorb water and sink while an unhealthy one will remain floating.

There are five fundamental qualities to consider when selecting mature seeds.
Cannabis plant sex organs appear on nodes, the points where branches grow off from the main stalk.
Some seeds germinate very rapidly while others can take a while, but generally, seeds should germinate in 3-10 days. If it’s been two weeks and a seed hasn’t sprouted, it’s probably a dud and won’t sprout.
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.

Pre-flowers can initially be extremely small and hard to identify with the naked eye, but you can use a magnifying glass to get a better look.
Seeds found in finished cannabis buds can develop for a number of reasons. For example, a male plant may have accidentally pollinated a flowering female during the growing process. But more commonly, they’re a sign of stress and can be attributed to high temperatures during the final stages of flowering or an exaggerated spike in climate or environment.
Even if your seed sprouts fast and grows vigorously, it still has roughly a 50/50 chance of being female and producing buds, instead of turning out to be a male.
So don’t discount bud because it has a seed or two in it. While not ideal, it could be the origins of the next great weed strain.
