PGR Problem Weed & How to Spot Them

Cannabis growers' most recent attempt to increase the quantity of cannabis they can produce by utilizing a variety of chemicals to alter the plant's growth cycles is known as PGR marijuana, or plant growth regulators.

Of course, one need not conduct much research to comprehend the concerns of chemicals found in consumer goods. There have been numerous occasions where a substance deemed "safe" resulted in an ailment or disease.

Such worries are heightened for individuals who use medical cannabis. The idea that PGR cannabis could be causing additional issues that you are unaware of when dealing with an existing significant medical condition is more than a little unsettling.

Many medicinal marijuana users look to cannabis as a natural substitute for medications, which makes them wonder if they aren't just switching one science experiment for another. In this blog post, we will look at PGR problem cannabis and how to spot them, including the risks they pose to people's health.

What Is PGR Marijuana?

Cannabis grown with plant growth regulators is known as PGR marijuana. PGR (plant growth regulator) crops are grown by some cannabis growers to improve development patterns and swell up valuable marijuana blooms. Buds grown with plant growth regulators (PGRs) are denser and thicker than those grown without.

However, using these plant hormones is not the most effective technique to get a good crop of cannabis. Cannabis cultivated under PGR has a pleasing appearance but lacks trichomes, cannabinoids, and terpenes. In addition to synthetic PGRs, natural PGRs can be employed successfully. For instance, cannabis growers can get the same spectacular outcomes as synthetic plant growth regulators by using kelp or chitosan. Plant growth regulators that are natural or organic have the added benefit of being safe for human food and the environment.

PGRs are frequently used on the unregulated black market. Cancer may even be brought on by synthetic PGRs, which can be hazardous to human health.

What exactly Are Plant Growth Regulators?

Dormancy, fruit development, shoot length, and size, among other things, may be governed by plant growth regulators. These PGRs result in lovely plants. PGRs are used by growers to improve marijuana health and mold resistance. With synthetic cultivars, gardeners sacrifice quality and safety for quantity while sacrificing taste and beauty. Growth inhibitors are alright. Because of the PGRs used, cannabis on the market has a poor PGR.

How to Spot PGR Cannabis

Outside of chemical testing, there is no 100% accurate way to determine if cannabis is PGR bud, but there are a few obvious symptoms to watch out for.

  1. The buds will be very compact. You won't get buds with a healthy, leafy appearance; instead, you'll get incredibly dense nugs where the plant is still tightly curled. It will feel thick and spongy, and you may sense the weight difference.

  2. The plant will have fewer trichomes that appear sickly. The white-to-clear, crystal-like structures covering the bud's outside are called trichomes. In the bud, they create both terpenes and cannabinoids. PGR cannabis will have much fewer trichomes or trichomes that are a sickly yellow-brown tint.

  3. Buds have a greater density of red or brown hairs. While some red or brown hairs are typical for cannabis buds, PGR buds contain many more.

  4. PGR marijuana won't smell strong. Fewer trichomes are present in PGR cannabis. Fewer trichomes mean fewer terpenes, which means less of the distinctive cannabis aroma. It's probably PGR cannabis if the bud doesn't smell particularly distinctive, even when it's been ground.

Synthetic PGRs Used in Cannabis Growing

Cannabis can be grown using a variety of PGRs. PGRs most frequently come in paclobutrazol, daminozide, and chlormequat chloride.


Of these three widely used chemicals, paclobutrazol may be the most dangerous, especially when smoked. Paclobutrazol undergoes a chemical shift when smoked, turning the substance into nitrosamines, which have been linked to serious diseases in studies. Notably, tobacco (cigarette) smoke contains nitrosamines, a carcinogenic substance.

The chemical chlormequat

This substance promotes flowering and makes plants grow more consistently and uniformly sized. Although chlormequat chloride may not be as cancer-causing as other synthetic plant growth regulators, it can harm the skin and eyes if it comes into contact with them.


The Environmental Protection Agency (EPA) designated daminozide, often known as Alar, as a potential carcinogen. Daminozide is no longer permitted as a spray for fruits, vegetables, and other food crops.

Is it Safe to Consume PGR Cannabis?

Synthetic plant growth hormones used to make PGR cannabis have been linked to negative health effects, including higher cancer risk. Cannabis created naturally or with natural PGRs does not pose the same health hazards as cannabis made with synthetic PGRs, which may be carcinogenic and are not suitable for ingestion by humans.

Synthetic PGRs may also be cancer-causing and pose the following health risks:

  • Inflammation of the skin and eyes

  • Organ injury (if large amounts are ingested)

  • adverse fertility consequences

The potential health consequences of synthetic PGRs require further study. To be safe, find out where the cannabis you consume comes from and only buy goods from reliable producers who follow ethical standards.
