GROW BOXES
A grow box (or earth box planter) is a self-watering plastic box with a built in reservoir. The outcome is that your cannabis plants are irrigated for a few days at a time with minimal effort, while maintaining the ideal moisture content in your soil at all times. The risk of weeds is reduced, and pest management is significantly easier (always use a mulch cover).
