hows it goin guys quick question i have just built a grow room in my attic it is 8x8x7 it will be a perpetual grow modeled after AL.Bs op. so the question is if i have 4 flood tables each with a 30 gallon nutrient resevour will i have any problem with the fact that a gallon weights about 8 pounds meaning ill have almost 800 pounds of water weight in my grow room does this present a problem as far as the floor in the attic holding that weight?
