Offshoots of surrounding plants can also knock your cannabis over, which is why harvesting early is sometimes a good idea. Stealth growing is another reason some opt to harvest before the plant is truly ready. While technically you can start harvesting as soon as your plant produces flowers, the cannabinoid levels remain very low until the buds are mature.
If you want to harvest the maximum amount of buds your cannabis can produce, then harvesting early isn’t a good idea. However, there are numerous reasons why you may opt to harvest a bit earlier than usual. Some of the most common reasons are bug and mould prevention. In less-than-ideal climates, poor weather can catalyse the onset of bud rot and other nasty ailments as the harvest season comes to a close. If you can’t move your plants inside to avoid harsh conditions, it may be worth doing a premature chop.
Although not set in stone, it’s important to at least consider the harvest schedule provided by your seed source. This is usually found on the seed packaging. This schedule is the approximate number of days/weeks it will take for your cannabis seed to grow into a mature plant. This schedule, however, fluctuates based on growing conditions such as environment, water, and heat. Always take this valuable breeder information with a grain of salt.
Yellow leaves are also a good sign that your cannabis plant is ready to harvest. You can flush your plant when its large fan leaves start to yellow or when they fall off by themselves. But bear in mind that the falling of leaves is unlikely to happen when you use fertilisers. So you might want to check for other clues to determine harvest time.
On the other hand, a late harvest means that you allow your cannabis plant to mature past the point of peak potency. Many consider this a bad method due to the degradation of THC—the cannabinoid most users want to take advantage of. And while the terpenes on buds are indeed more pungent when allowed to mature, the flavour and aroma will go south if kept alive too long.
Harvesting your cannabis plant is all about proper timing. Harvest too early and you won’t get any psychedelic effects; harvest too late and you run the risk of self-pollinating and rotting. Hence, balancing things out is the key to achieving the best harvest.
If you find yourself slightly perplexed by the notion of determining when to harvest, then read on—we’ll cover everything you need to know.
Trichomes go through three consecutive colour states. These are clear, cloudy, and amber. The best time to harvest is when half of the trichomes are amber, and half are clear or cloudy. This colour disparity is due to the uppermost buds ripening earlier than the ones at the bottom. In any case, you don’t want to wait for all trichomes to turn amber, as this generally leads to a decrease in THC and an increase in the sleep-inducing cannabinoid CBN.
Avoid premature harvesting as much as possible, but if you really need to, it isn’t the end of the world. If you only harvest a few days early, the “damage” to potency will be minimal. Some bud is better than no bud at all!
