Lets see here. 325000 gallons divided by 365 days is 890 gallons per day. Mature plants need 12 gallons per week minimum. So if we divide 325000 by 52 weeks we get 6,250 gallons per week. Divide that by 12 gallons per plant per week and you can water 520 plants. I really need to know how you figure this will work for Phase 1 and 2. It might work for one small greenhouse. Im really curious how you think such a small amount of water will support your 16 plus greenhouses. I had no idea you had such a small amount of water. Thanks for telling me. I must admit I am falling on the floor laughing my but off. I am definitely the one laughing now. WHAT A SCAM!!
