cannabis seed to harvest time

Seed germination length: 3-10 days

The growth stages of marijuana can be broken down into four primary stages from seed to harvest:

Notes on marijuana growth phases

Outdoors, flowering occurs naturally when the plant receives less light each day as summer turns into fall. Indoor growers can trigger the flowering cycle by reducing the amount of light marijuana plants receive from 16 to 12 hours a day.

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.

Important dates for growing marijuana outdoors

Within the flowering stage, there are three subphases:

Some people put their seedlings or clones right into the flowering stage if they want to harvest quickly though this makes for extremely small plants. For example, super-stealth growers who are growing in small hidden spaces – like out of a computer case – would want to put their seedlings into flowering nearly right away to keep their plants as small as possible. It’s also important to remember that container size and grow lights make a big difference. Small containers constrain the roots and keep plants from getting as big as they could, and small lights prevent buds from fattening up as much as they could.

To give you an idea as to what your FINAL marijuana plant may look like depending on how long it spends in the vegetative stage…

A good rule of thumb…

Time Needed to Grow Weed, From Seedling to Harvest

Total Time to Grow (and Be Ready to Use) Your Own Weed:
8 weeks – 5+ Months

Two weeks is considered the minimum time to cure your buds, but I personally cure all my buds for a month or even a bit longer because the buds continue to improve for several more weeks.

Before You Start Growing Weed

Here’s a list of some of my favorite and best cannabis strains by the length of the flowering period:

These cannabis plants were vegetated for about 8 weeks before being flipped to the flowering stage. Although they were grown in the exact same conditions from seed to harvest, their final heights are remarkably different because their strains had vastly different genetics. The smaller plant produced 6.6 ounces, while the big plant produced 9.3 ounces. Strain can make a big difference! Learn about growing different strains together.

Only now can the sex be determined with any certainty. While male plants produce pollen, the female plants pour their energy into producing flowers or buds. Most growers want to prevent their female plants from getting pollinated, because then they start to produce seeds. That is why male plants should be removed from the growing area.

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:

As it grows, the plant also needs more water. Young plants are best watered close to their stem, but later on water should be distributed more widely so that the tips of the roots can absorb water more efficiently.

The germinated seed can now be placed carefully into the growing medium. The plant will start to grow and force its way upwards.

How to Harvest Cannabis Plants

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.

Now the plant starts its main growing phase. Provided it receives enough light, it can grow up to two inches (5 cm) in a single day. It is obvious that the plant needs to be repotted if it is still growing in a small pot.

Leafy plants like a healthy soil that is rich in nutrients. The production of chlorophyll and proteins depends on a supply of nitrogen. It is worth investing in the right kinds of fertiliser or even producing them yourself.

1 – Germination stage (1 to 2 weeks)

Particular care is necessary at this stage in the lifecycle. Seedlings are susceptible to illnesses and mould. Many novices get carried away with watering and give the seedlings too much fertiliser. Even if you plan to grow outdoors, it may be useful to give the plants a healthy start indoors, assuming that a location is available with adequate light (e.g. a windowsill). The plants need as much light as possible at this stage.

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.
