During this time, the plant will also start developing its root system. While this is happening, it is officially a seedling. Pot plants can stay in the seedling stage for 2-3 weeks, but this stage may last for up to 6 weeks in rarer cases. The length of time can vary depending on the strain you’re growing and a few environmental factors.
A good trick is to look closely at the pistils. When they begin to turn brown, and the leaves start to yellow, now is the time to harvest. Generally, experts say you should harvest the plants when 70-90% of the pistils have browned. If the pistils are entirely brown, the marijuana may be ‘overripe’ – it won’t taste good, and its effects will be less pleasant.
4. Flowering Stage: 6-8 Weeks (Most Important Stage!)
As a result, you should look out for feminized seeds. Seed banks often sell this type, so they shouldn’t be too hard to find. If you use regular seeds, there is a 50/50 chance you will get male or female plants; with feminized seeds, all your plants will be females.
Before you start, though, it’s crucial to find out the laws in your locality. Growing weed in a state where it’s illegal can carry hefty penalties, so it’s just not worth it! Make sure you stick to the laws in your state, and you will find the experience much more pleasant.
At this point, you should keep the temperature somewhere between 68 and 77˚F, with the humidity at around 50%. You can stop giving the plant nitrogen now, but up the intake of potassium and phosphorus.
Now that you’re familiar with the distinctions between photoperiod and autoflowering strains, we can begin to break down each stage involved in cannabis cultivation.
It’s always best to evaluate if a cannabis plant is ready to harvest by taking a closer look at those resin dripping buds. Using an inexpensive scope to zoom in on those resin heads to make sure they are milky and amber rather than clear removes all the guess work.
Ultimately, the most important use for your magnifying glass is to detect the progress of your trichomes, and therefore, the proper time to harvest your buds. Trichomes are small mushroom-shaped glands that produce resin which contains the vast majority of cannabinoids and terpenes.
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.
You can trim your cannabis plants in one of two ways: wet or dry. Both have their own advantages, and each grower will differ in which one they prefer. Wet trimming refers to trimming off the sugar leaves surrounding the buds immediately after harvest while the plant still has a high water content and feels “wet”. This method is the most common, and arguably the easiest, as it doesn’t require a large room to dry out plants beforehand. However, wet trimming is literally sticky business. The resin from the flowers will cover both your hands and your scissors, but there is an upside to this. By scraping the resin from your scissors every now and then, you’ll quickly build up a supply of “scissor hash”, allowing you an early taste of your harvest.
