how long does it take weed to grow indoors

Cannabis plants go through a series of stages as they grow and mature, and those different growth stages call for different amounts of light, nutrients, and water.

How long does it take to grow a marijuana plant?

Once your seed has germinated, or sprouted, it’s ready to be placed in a growing medium, like soil. The tap root will drive down while the stem of the seedling will grow upward.

What are a weed plant’s growth stages?

The Spring Equinox is a good reminder that it’s time to kick off the outdoor growing process and start germinating your seeds.

And there is. Luckily, the flowering time is the easiest to shorten. We’ll follow up our breakdown of each stage with some specific tips for speeding up your marijuana grow. You can also shorten veg quite a bit, by growing smaller plants instead of larger ones.

Germination

If you let the plants veg for longer, they grow larger and are able to grow a lot more buds. Of course, the size your plants can achieve is also constrained by the size of the pots they are in and the amount and strength of the grow lights.

Time Required: 5 to 16 weeks (or more for select strains)

If speed is the only thing that matters, you could switch to a 12/12 light cycle and begin flowering as soon as possible. Of course, this will result in much smaller plants and correspondingly smaller yields. We definitely do not recommend this, unless it is your goal to have small plants.

The size your plant achieves in the vegetative stage has a very large effect on your final yields since bigger plants produce more bud sites than smaller plants. However, you need enough light to cover all the bud sites or they will never develop properly. Light is like food for bud growth!

Flowering Stage
Flowering Stage: (average 8-10 weeks, length depends on the strain/genetics)

Before You Start Growing Weed

These cannabis plants were vegetated for about 9 weeks before being flipped, in the exact same setup as above, and produced over 10 ounces each. Besides an extra week of veg, the biggest difference between this grow and the one above was simply the strains.
