cannabis from seed to harvest

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.

PHOTOPERIOD PLANTS

This is the stage to pot up photoperiod plants into final containers, at least a couple weeks before switching to bloom or prior to Summer outdoors.

Now that harvesting and trimming are complete, it’s time to cure your flowers. Curing is an essential process that removes the last of the residual water from the buds, minimising the chance of mould and greatly prolonging shelf life. Curing also enhances the taste and quality of the smoke, making for a smooth and potent experience.

Two tiny leaves will open up from the top of the sprout as it emerges from the growing medium. These are called cotyledons and they provide the necessary energy for first stages of growth as photosynthesis begins.

Sprouts need very stable conditions if they are going to thrive. The average temperature levels they do best in are between 20-25°C, with a humidity level of around 60-80%. They will require watering but only small amounts to keep the growing medium moist enough to encourage root growth. Because there are basically no roots yet, the absorption of water is minimal meaning watering too much can drown them easily.

A few days after this, the first ‘real‘ leaves start to grow from the centre. The cotyledons will turn yellow and fall off eventually when the plant has matured into its vegetative state.

Germination (1 week)

After 2 weeks cannabis plants will be in their vegetation phase. During this part of the cycle there is a lot of development happening in both the root zone and the main structure of the plant. There will be a surge in the branching activity and small shoots can be noticed emerging from the leaf nodes.

As soon as a seed recognizes it has moisture surrounding it, the cells in the seed germinate and begin forming a tap root. Once this white root shows, a seed has germinated and is now considered a sprout.

Tip: Seedlings enjoy high humidity and warm temperatures. Keeping a consistent environment for them helps them to progress much faster, so a propagator is recommended. The vent holes can be opened slowly each day so they steadily become accustomed to the change of environment.

Note: The signs of a hermaphrodite can be determined by ‘bananas’ growing from bud sites. As the name suggests, they look like tiny yellow bananas and are quite obvious when they do appear. Hermaphrodites should be removed from a garden immediately if you are not looking to breed your plants.
