How often should I flood my small, Baby Bloomer ebb & flow tray that contains small pots filled with Hydroton? The drainage is good. There is not allot of heat in the closet because I am using LED lights. The plants are Stevia plants and are like a foot tall or something. They are in small like 4 or 5 inch pots that sit in the flood tray. I don't flood the tray too much because I don't want to over-water. But I do flood it like one or two times a day. Would more floods make my plants grow faster? Thanks.
