Hello everyone. I am getting everything set up for my first grow. My thought was to elevate my grow bags by setting them on a stainless steel grate like the ones found in a grill. The grate would be propped up off the floor by maybe 2 or 3 inches to allow for air flow and tray to catch spillage. My question is... Is it better to leave bags on floor in a spill tray? Would my bags dry out too fast on a grate?
