i was just wondering for my new project about hydroponic i wanna know do i have to use gro rocks or just any rocks as long as they are clean. Do i have to fill the bucket up with water until it reaches the bottom of the pot? Will any kind of food coloring change the leaves the same color as the food coloring?
