It is nice to have a flood table to drain your plants after watering,I use one large screen made from string and cut the string out after the first plant is finished.the rest of the plants seem to keep their shape and i can now move them to the center of the light. I used this method for a few years and now i put 16 plants in two gallon pots in my 4 by 4 closet and end up with a few more ounces each grow
