marijuana seed growth time

The long answer is: from Day 1 of your weed plant’s life to actually smoking your harvest, it can take… 8 weeks – 7+ Months! That’s a huge range, right?

This includes the time needed to grow your cannabis plant from seedling to harvest plus an additional 2 weeks (or more) which is used to cure your cannabis buds after harvest (making them more potent and better smelling).

Before You Start Growing Weed

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.

That’s why most cannabis growers won’t give you a straight answer. The truth is, there are many factors will affect the total time until you have ‘ready’ buds, by days, weeks or even months. This includes your strain, your setup, and how big you plan to grow your plants (bigger plants need more time!). So instead of giving you a huge range, an easier-to-swallow answer might be to say that the average grow takes 3-5 months for indoor growers.

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…

• Flowering stage
Time: 5–16+ weeks

• Germinating your seeds
Time: 1–7 days

How long it takes for cannabis to mature its buds can vary greatly depending on genetics. Some indicas bred for speed can be ready after 5–7 weeks of bloom. However, the average flowering time for most indicas and hybrids is usually 7–10 weeks depending on the strain.

PREPARATION TIME BEFORE YOU GROW

3. Vegetative stage (2–8+ weeks) – The vegetative stage could last indefinitely if we’re talking photoperiod (non-autoflowering) strains. Most growers let their plants vegetate for a month or two, or until their plant has a reached a certain size. Bigger plants can mean bigger yields, but how long you veg depends on available growing space.

1. Germination (1–7 days) – When your seeds “come to life” and begin sprouting.

4. Flowering stage (5–16+ weeks) – This is the reproductive stage of cannabis when it begins producing buds. How long your cannabis needs to ripen its flowers greatly depends on the strain you are growing. Fast-flowering indicas can be ready after about 55–60 days of flowering, whereas some sativas could take a few months for their buds to ripen.

2. Seedling stage (10–15 days) – The “baby-phase” of your freshly sprouted cannabis plant.
