Keeping the air below 75 degrees will also discourage them. Avoid letting pets into the grow room and never enter the grow room wearing clothes that may have come in contact with other plants, especially house plants. Simple homemade or store bought soap and water concoctions can be sprayed on leaves to suppress mite or bug infestations.
Spray the underside of leaves where mites live. More serious cases may necessitate insecticides. Different products are available for different pests. Predator insects, such as lady bugs, are sometimes used to consume mites. Most growers avoid using insecticides that are not designed for plants bound for human consumption.
For simple, homemade, light-duty mite insecticide, mix a teaspoon of dish soap into a jug of water and spray on the undersides of leaves. A higher concentration of soap can be used, but may require a follow-up rinse of pure water the next day to remove soap residue. Soap spray should not be used on buds.
