weed cycle from seed

Buds typically grow the most toward the end of the flowering life cycle. You probably won’t notice much budding out at the beginning of the flowering stage, and it will slow down toward the end of the cycle, when buds become fully formed.

If you buy a clone from a grower or breeder it will be a seedling, so you can skip the seed germination phase.

Seed germination length: 3-10 days

Flowering stage

Cannabis plants are considered seedlings until they begin to develop leaves with the full number of blades on new fan leaves. A healthy seedling should be a vibrant green color.

As roots develop, the stalk will rise and you’ll begin to see the first iconic fan leaves grow, at which point your cannabis plant can be considered a seedling.

We can’t stress enough that the timeframes in the above graphic are ranges of time for the Northern Hemisphere. You’ll need to adjust them based on your specific region and local weather and climate.

If you want to keep all your seeds safe and clean, we recommend the Royal Queen Seeds Starter Kit. With that, they can enjoy clean, undisturbed germination. Once they get to 2–3cm high, you can remove them from the starter and place them in a suitable growing container.

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.

The main marker of a photoperiod plant is the potential for indefinite vegetation—as long as you keep the plants on an 18/6–24/0 light/dark cycle. We’ll talk more about that later, but it means these plants can withstand more mistakes in the growing process. It also means you can ensure your plant produces the best crop possible once you initiate flowering. All you need to do to make the switch is adjust the light cycle to 12/12. This becomes even more useful when you’re able to make unlimited clones of your optimised plant. The main drawback is that it’ll take around four months to get a substantial yield. However, you’ll have a larger and usually more potent plant once you’re there.

Autoflower cultivators have even less time to play with than photoperiod growers as most autos will race into flowering after just 2-3 weeks of vegetative growth. It’s for this reason that many auto growers plant their autoflowering seeds directly into the final container. The clock is ticking with autos from the moment of germination.

Flowering generally lasts 7-10 weeks for indica and hybrid photoperiod cannabis strains, while the more Sativa dominant strains can take 10-14 weeks to fully ripen into primo head stash.
