My D.W.C Set up almost done!!!. I was going to flower with two 600 bulbs But.... I was talked into Growing with two 1K bulbs. I got one 1k ballast and two hoods yesterday. All I have to buy is One more ballast,inline fan and two bulbs. My D.W.C flows 480 gallons a hour threw my rez. I plan on setting up another 40 gallon water rez for ph water. Right now I only have a 37 gallon R.O rez hooked up with a float valve to auto fill. My veg side I got the water pump. 300 gph to flow from 5 gallon rez. If I have time I will have water pump inline this weekend. I will post more pic a I get things done.
