cannabis seeds to harvest how long

Even when your plant is a mere seed, the work you put in will dictate its success or failure. Germination is the stage when the first root cracks out of the seed’s shell, which takes between 1–7 days. The wet paper towel method is a classic approach here, but you start out with the major setback of tiny fibres all over your new root. You can plant directly in the soil, of course, but you need to ensure temperature and moisture are dialled in.

Harvesting is the most rewarding part of the cultivation process for many growers. Watching your plants grow over several months is mesmerising, but finally harvesting the fruits of your labour truly is the peak of the experience. The flowering phase of the grow cycle typically lasts between 7–11 weeks, after which it’s time to strip your plants down of their buds. However, you don’t want to do this too early and prevent your flowers from fully maturing. Likewise, you don’t want to wait too long. Timing harvest is a crucial step, and there are multiple signs you should look out for to know when the time is right.

PHOTOPERIOD PLANTS

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.

If you see “nanners” or anything resembling a cluster of grapes protruding from flowers or anywhere on the stem then you have a male cannabis plant. Should you see both hairs and nanners then you have a hermie to remove right away.

Once you confirm you’ve got a ripe marijuana crop on your hands it’s time to break out the trimming scissors and get harvesting. After two weeks slow drying in paper bags or hung up, at room temp and approximately 50% RH, you’ve got a stash.

What if time is not an issue?

In order to achieve the shorter 8.5 weeks, you need to choose a fast-finishing strain like Northern Lights and even still, at the low range, you’ll be growing tiny plants that produce just a few grams of smokable harvest.

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.

Long Anwer:

Depending on how you set up your grow, it can take anywhere from 2 months to 6 months or more to grow a marijuana plant from a seedling to the point where the plant is ready to harvest. Some methods, such as growing hydroponically indoors, give your flexibility to get a harvested plant in as little as 2-3 months. Growing outdoors generally takes longer than growing indoors and is more dependent on when you plant your seeds and how long your growing season is.

Important Milestones in the Marijuana Plant’s Life

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.

These factors have the greatest impact on total time:
