If you know of any supplement manufacturers who have tested their products on real cannabis plants and can demonstrate that their supplements actually increase THC, we’d love to hear from you!

Letting plants get older before the switch to the flowering stage definitely results in bigger plants and higher yields, but we don’t know if it increases cannabis potency!

There are certain techniques that will definitely maximize the THC produced by your cannabis, and there are other methods which may increase potency but their effects are less certain.

Though not well understood, this is likely due to chemical changes that happen during the curing phase that “intensify” the effects of THC and other cannabinoids.

Supplements to Increase THC and Overall Potency

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.

The sinsemilla bud that started flooding the market was much higher potency than the seedy, low-quality bud that had been available before. This led to the term sinsemilla being used to describe very high quality and potent cannabis. There’s no doubt that most growers prefer buds without seeds, but the term sinsemilla has led to the idea that cannabis buds without seeds were inherently more potent than seedy bud.

This means that the plant puts all its energy into producing resin and improving the cannabinoid content of its buds. More resin production translates to a bigger harvest and higher quality buds with potent THC levels.

Topping involves cutting the top of the cannabis plant, so it grows bushier rather than taller. This results in the plant developing two apical buds, also known as colas. They are the largest blooms on the plant, so having two will increase the yield.

Some growers have a technique for keeping a growing plant in its vegetative stage for 8 weeks at least. This means that the cannabis plant is induced into growing more vegetative parts before it is switched to the flowering stage. The increased length in the vegetative stage means a larger yield and can lead to very potent buds when combined with powerful grow lights.

Being able to produce higher THC levels and cannabinoid levels in the plant has several benefits, from achieving more significant psychoactive effects to inducing stronger relief from pain, nausea, and multiple sclerosis, or for merely maximizing yields.


Curing your buds also has the added advantage of reducing the speedy effects of under-developed buds.

If you have a Grobo , no need to worry about nutrients! Our 850+ strain recipes will automatically dose the perfect amount of nutrients to your plant throughout each growth stage, including the flowering stage and vegetative stage.

The factors we’ve looked at so far are strictly designed to increase THC levels of cannabis only. However, they aren’t the only known growing techniques that affect THC levels.

Providing the Right Amount of Nutrients

The following growing methods should help with increasing yield in addition to influencing the production of highly potent buds:

Dropping the temperature of your grow space to about 10-15 °F simulates fall and the beginning of winter. This helps to trick the plants into “panic mode” where it rushes to finish its flowering stage before the extreme cold kicks in.
