Hydrogen peroxide (H₂O₂) is a chemical compound consisting of water with an additional oxygen molecule, and it has powerful antiseptic and oxidizing properties. It is widely used in commercial, residential, and industrial settings, and the cannabis sector is no exception. In fact, the answer to controlling pests, fungi, and root rot might just be this handy liquid chemical. Read on to explore the most common and practical ways cannabis growers can use hydrogen peroxide.
As a Fungicide
Fungal infections can devastate a cannabis crop, but hydrogen peroxide can come to the rescue. The chemical is a powerful fungicide because it breaks down the cell walls of fungal organisms, killing them on contact. Moreover, you can apply H₂O₂ as a preventative measure to reduce the risk of fungi developing in the first place.
As a Pesticide
Pests are a recurring problem for cannabis growers, and many pest control methods affect the quality and safety of cultivation. Hydrogen peroxide, on the other hand, is an effective alternative to chemical pesticides. It eliminates soft-bodied pests by oxidizing their outer shells and destroying their eggs on contact.
As a Tool Disinfectant
Using dirty tools to tend to and test your cannabis could corrupt the plants with harmful bacteria, spores, or pests. Avoid contamination by disinfecting your tools in hydrogen peroxide, especially the tools you use for testing. After all, the testing stage is where you guarantee your plants are pure and safe for consumption, so any contamination exposes you to legal ramifications. Hydrogen peroxide supports lab disinfection and sterilization in the medical and scientific communities as well, so you know it’s a safe, proven method.
As a Treatment for Root Rot
Root rot suffocates cannabis plants and hinders nutrient uptake. It can occur due to overly saturated, compacted soil conditions and usually an accompanying fungal or bacterial infection. Once again, hydrogen peroxide saves the day with its antifungal, antimicrobial, and oxygenating properties. It kills whatever harmful growth is attacking roots, and it loosens up the soil for your plants to breathe better.
Tips for Using Hydrogen Peroxide
Now that you know the ways cannabis growers can use hydrogen peroxide, how do you get started? You must always mix hydrogen peroxide with water before treating your cannabis plants (or buy premixed solutions), and the level of concentration varies. For instance, a ratio of 3 ml H₂O₂ and 100 ml of water works for spraying on leaves to kill pests, while reducing the H₂O₂ to just 1.5 ml works for preventing pest infestations. However, this is a guideline formula that may not work for your plants. Therefore, before commencing any treatment, make sure to research the proper concentration for your application and whether you should deliver the chemical via spray or irrigation. Best of luck!
