I was teasing on the wife thing she is the salt of the earth and can usually talk me out of stupid ideas like this but i just read where in europe they have galvanized metal roofs,catch the rain off of them store it in galinized metal barrels and then drink it,also they still use even in my area galvinzed metal animal waterers.Also I understand Im not going to have 1 big tray. For instance in the 3x11 room the door is about in the middle of the 11 ft side well you walk in barely enough room to turn around so I thought 1 3 foot by 4 foot tray to my right for veg growth and 1 4 by 3 to my left for clones and mamas leaving a 3x3 to stand in the middle.Also Godess I appreciate your feedback.Truly
