Peppers and tomatoes can both use hanging basket setups w/rubber seals.. you put the plants in, put soil in the middle.. and it's a gravity setup - last time I was in the dollar store, saw the setup for 5 bucks and it held 12 plants.To be 100% honest with you I am not sure. I havent met anybody who has done or tried this method. Now I can say this tho, for 5yrs now I grew tomatos and peppers this way and when harvest time comes the crop is bigger/denser juicier, high quantities, and its looks great. Makes u proud
Tomatos and peppers make sense because they produce fruit. The cannabis plant doesn't produce pluckable fruit so how would that benefit us, or them, from growing upside down?
