Unfortunately, at this time there aren’t any supplement companies that have conducted systematic tests showing that their supplements will actually increase THC. Because of this, although it seems possible that some of these do work as stated, I can’t recommend any ones in particular.
Air Temperature, Humidity and Overwatering
However, there are several additional types of flushes that many growers believe will increase THC levels. Most of these are done in addition to regular flushing, just before harvest. Unfortunately, there aren’t many (if any) tests determining which one of these work, but there are many experienced growers who swear by these methods!
Lack of Pollination (Producing “Sinsemilla”)
In order to get your cannabis to produce the most potent buds possible, you need a robust, healthy cannabis plant with lots of bud sites getting direct light during the flowering stage. This means it’s important to avoid common plant health mistakes like overwatering, underwatering, heat stress, root problems, irregular light cycles, and nutrient problems. Check out our 7-step remedy to fix most cannabis plant growing problems. Try to maintain balance and avoid environmental extremes. Basically, treat your cannabis plant like it’s a celebrity – it gets everything it wants!
I’ve heard this one from different growers over the years, but for now, the jury is still out. The idea is that a cannabis plant needs to remain in the vegetative stage for at least 8 weeks before being switched to the flowering stage in order to reach its maximum THC levels when it starts budding.
Although there is no evidence that the curing process (jarring up buds after they’ve dried) increases THC levels directly, there is a lot of evidence that it increases the perceived potency of buds.
A: You shouldn’t have any issue with handling the plant, but the scent is very pronounced, so you may smell like marijuana.
A: Place the clone in a pot filled with a planting medium. Although potting soil would technically work, we use a soilless growing media made from coco fiber, worm casings, perlite and vermiculite because it’s developed specially for marijuana, even though (manufacturers) don’t admit that. You can get premixed versions at grow stores — Royal Gold Tupur is a good brand.
Dan Ericson trims the "sugar leaves" — the single leaves close to the bud — off a pot plant, readying it for the drying process. Then he'll hang the plant upside down for a week to dry.
If you’re 21 or older, Amendment 64 allows you to cultivate up to six marijuana plants in an “enclosed, locked space” in Colorado. (This is still illegal under federal law.)
Care, air and food
Q:What type of container is used?
A: Many people use 5-gallon plastic buckets, but those create problems because the roots just wrap around themselves and form a large root ball. If you use a 3- to 5-gallon fiber pot, the root sticks through the pot and (the plant) air-prunes itself, while feeder roots grow in the pot. That gives the plant a larger nutrient intake.
Q: Can THC be topically absorbed? Could people who grow fail a drug test if they touch their plants?
Then you want to throw the plants into the flower cycle (12 hours of light followed by 12 hours of dark). During the second to third week of flowering, prune the bottom third of the plant so it puts its growth energy into the top once buds form.
