marijuana 2 weeks from seed

Once your seed has germinated, or sprouted, it’s ready to be placed in a growing medium, like soil. The tap root will drive down while the stem of the seedling will grow upward.

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.

What are a weed plant’s growth stages?

It’s important to know these stages and how long each lasts to know what the plant needs and when. Knowing where your cannabis plants are in their life cycle will dictate when to prune, train, and trellis your plants, and when to harvest.

Cannabis plants go through a series of stages as they grow and mature, and those different growth stages call for different amounts of light, nutrients, and water.

The weather will start to turn and the sun will begin descending in the sky as your plants fatten up with sweet, sticky buds. It might be tempting, but wait until around the Fall Equinox to start harvesting.

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.

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.

This is the point where it starts to look more like a cannabis plant. There will be one ridged blade per leaf at first, but the blades will get closer to their typical 5–7-finger stage by the end of this period. Until they get the full 5–7 blades, though, the plants are considered seedlings. Along with the increasing blade count, a vibrant green colour is another mark of a healthy plant. To keep them healthy, the two main things to keep an eye on are water and cleanliness. Seedlings are still fragile, so only light watering is necessary. Cleanliness is equally vital due to their disease and mould vulnerability. The perfect home for cannabis seedlings is a propagator, ideally with 70% RH and temps 20-25°C, under either white CFL lights or LED’s.

HARVESTING

If you see “nanners” or anything resembling a cluster of grapes protruding from flowers or anywhere on the stem then you have a male cannabis plant. Should you see both hairs and nanners then you have a hermie to remove right away.

Photoperiod strains are induced to bloom by the hours of light they receive; indoors the grower changes to a 12-12 light-dark cycle to artificially promote flower growth.

While the photoperiod strains can be kept in veg weeks or even months to allow for all kinds of pruning and training to boost yield like topping, FIM, LST or even a ScrOG the Auto grower is somewhat limited by time.

The way these differ from photoperiod plants is written in the name. Regardless of whether you feel the plant is ready, it’ll start flowering at a certain time depending on the strain’s genetic programming. In one sense, these plants are easier for novice growers because there’s less to think about in regards to light coverage and cycle adjustment. On the other hand, due to the limited vegetation time, you have fewer opportunities for mistakes. This isn’t ideal for first-timers, but the fact that it only takes two months from germination to harvest is definitely appealing. Autos tend to produce lower, milder yields than their photoperiod counterparts, but modern advances are bridging the gap.
