Responsible home growers know how vital it is to understand the risks associated with PGR weed. PGR, or plant growth regulator weed, refers to cannabis plants that have been treated with synthetic chemicals to enhance their growth.
In recent years, the use of PGRs in cannabis cultivation has sparked controversy because of the potential health risks that they pose. That’s why it’s necessary for growers to be aware of the top causes of PGR weed so they can grow safe and healthy cannabis plants.
Kind Seed Co. is a forward-thinking cannabis authority that’s here to help you grow healthy and thriving cannabis plants. Today, we’ve brought you a list of the top seven causes of PGR weed and some tips on how to prevent it.


What is PGR Weed?
Plant Growth Regulator (PGR) weed is cannabis that has been treated with certain chemicals to influence growth. These substances can manipulate certain plant processes, like aging, rooting, blooming, and fruiting. The use of PGRs in cannabis cultivation is a contentious issue, with some arguing that it can lead to a more robust yield, while others caution against the possible health risks.
The controversy lies primarily in the use of synthetic PGRs, which are chemically created to mimic natural plant hormones. These synthetic versions have been linked to a range of health problems, including hormone disruption and even cancer. Therefore, understanding the causes of PGR weed is crucial for responsible cannabis growers.
Top 7 Causes of PGR Weed
At Kind Seed Co., we’re committed to sharing information to help home growers be responsible and successful. These top seven causes of PGR weed need to be understood.
- Use of Synthetic PGRs: Synthetic PGRs are tempting because they promise accelerated growth and greater yield. However, these chemicals can leave residues in the plant that can cause health problems when consumed.
- Over-fertilization: While fertilizers are crucial for cannabis growth, over-fertilizing can lead to an imbalance in the plant’s natural growth hormones, which can result in PGR weed.
- Poor Light Quality: Proper lighting is required for optimum growth. Poor-quality light can slow photosynthesis, leading plants to rely more heavily on PGRs.
- Inadequate Air Circulation: Poor air circulation can increase humidity levels, leading to mold growth. This can stress the plant and stimulate the use of PGRs.
- Incorrect Watering Methods: Over or underwatering can stress the plant and make it more reliant on PGRs to maintain growth.
- Poor Soil Quality: Healthy soil is crucial for cannabis growth. Poor soil quality can lead to a need for additional PGRs.
- Incorrect Temperature and Humidity: Temperatures and humidity levels that are too high or too low can lead to stress in the plants and trigger an increased use of PGRs.
How to Prevent PGR Weed in Home-Grown Cannabis
Here are several ways that you can prevent PGR weed in your home grow setup:
- Use natural PGRs that are safer alternatives to synthetic PGRS and don’t pose the same health risks.
- Be aware of the amount of fertilizer you use to prevent over-fertilization.
- Use high-quality lights and adjust them accordingly to the growth stage of your plants.
- Maintain adequate air circulation to help control humidity levels and discourage mold growth.
- Stick to a consistent watering schedule to avoid over or underwatering.
- Regularly test and amend your soil for optimal growth.
- Monitor your growing environment diligently to ensure it’s suitable for cannabis cultivation.
