Flowering stage length: 8-11 weeks
Be sure to keep a grow journal to track the progress of your plants. Looking back on your notes will help you learn from mistakes and maximize the quality and quantity of your buds.
At this stage, the plant is vulnerable to disease and mold. Keep its environment clean and monitor excess moisture. Be sure to give it plenty of light.
Marijuana light cycle: 16 hours a day
Two rounded cotyledon leaves will grow out from the stem as the plant unfolds from the protective casing of the seed. These initial leaves are responsible for taking in sunlight needed for the plant to become healthy and stable.
Be mindful to increase your watering as the plant develops. When it’s young, your plant will need water close to the stalk, but as it grows the roots will also grow outward, so start watering further away from the stalk in the soil so roots can stretch out and absorb water more efficiently.
Take meticulous notes on when and how you perform each step, as well as what the weather is like. Other notes can include how much water you give plants, at what intervals, and how much nutrients you give them. Pictures will also give you a better sense of how your plants look along the way.
Exactly how long this period lasts depends on the type of plant you are growing. Autoflower strains have a short growth phase of about 2 to 4 weeks. Photoperiod cannabis varieties, when grown outdoors, can have a growth phase of up to 2 to 4 months while, when grown indoors, they can go into flowering after just 6 – 10 weeks.
How long the flowering phase lasts depends entirely on the variety you are growing, but it can be said that an average flowering time of both autoflowers and photoperiod varieties lasts 9 weeks.
Phase 2 – Growth phase
During this phase, as a grower, you apply a light cycle of 18 hours of light and 6 hours of complete darkness. A proper balance of light and dark without interruption is the key to a perfect growth phase.
To briefly answer the question. Growing a photoperiod cannabis plant takes an average of 4 to 6 months. If you grow an autoflower, then it is usually ready to be harvested within 3 months. This does not include drying and ripening which takes about 1 to 2 months.
The strictly necessary germination phase is defined as the time it takes for the seed to develop into a seedling. If you are using cuttings, this germination time is referred to as the cloning and rooting time.
One of the fastest grow methods is growing marijuana with bubbleponics, which shaves a few weeks off the total time and will actually increase your yields, but it requires a bit more equipment to get started.
Strains from warm climates like Haze 1 tend to have long flowering periods before their buds are ready to harvest, adding weeks or months to the time needed. Long-flowering strains often produce higher yields than short-flowering strains because buds have more time to grow.
The time from seed to smokable harvest averages 3-3.5 months for me with a strain like Northern Lights, where I grow the plants for 3-4 weeks in the vegetative stage, growing with cheap, regular CFL lights in coco coir, and with that setup I can get a few easy ounces per plant.
Once your plant is harvested, there is a drying and curing process which takes about a minimum of two weeks before your buds are “ready” for use.
