marijuana seed germination timeline

Cannabis is an annual plant, so its entire lifecycle takes place within a single year, with most varieties reaching the end of their life after between four and ten months. In general terms, the following four stages of life can be distinguished:

Plants are living beings. They are at the base of the evolutionary tree, they heal our bodies and souls, they delight our senses. I think all our readers know by now which is our favourite plant: Cannabis sativa L. – a fantastic crop and medicinal plant, and one of the oldest plant genera in the world.

1 – Germination stage (1 to 2 weeks)

No matter why cannabis is being cultivated, to see with your own eyes how a small seed grows into a bulky plant, which then starts flowering, is a moving experience every time.

How long the seedling stage lasts depends on the variety and on the environmental conditions. The main focus of the plant is on developing a root system. This forms the foundation for its later growth.

While the first two cotyledons (seed leaves) are being formed, the plant shrugs off the protective seed husk. That signifies the end of the germination stage.

At this stage, the focus of the grower and plants switches to the production of buds and the grower is already dreaming of a frosty marijuana harvest in the near future. RH needs to be reduced to 40-50% and temps kept between 20-28°C.

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.

STAGE 1: GERMINATION — 1–7 DAYS

Earlier on in the flowering phase, trichomes will appear translucent, meaning they are still developing and should be left to mature. When approximately 60% of the trichomes develop a milky look, they are ready to harvest. It’s at this stage where they will produce the most significant high . However, some growers wait until up to 90% of trichomes move past this milky look and become amber, as this will cause the buds to develop a more stoning and sedating effect.

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.

Cannabis plants will first give you an indication of their sex in the early phase of bloom. Typically within the first two weeks of flowering females will develop pistils or “hairs” to confirm their femininity.
