I have a lumatek 600 watt switchable ballast. I used pvc to build the frame of my hut and black and white plastic from the hydro store. Right now I have 2 45 watt cfl's on my plant till they get a little bigger unless you guys think I can just switch on the hps. I didnt know I bought a switchable ballast at first. So I do not have a mh light. I have a hps bulb that I will leave on for 18 hours on 6 hours off. My hut is about 4x2.5x6.5. Total cost to build the 50 bucks. I accidently bought the ff grow big for soil does it matter if I use it in hydro. I also didnt get enough material to make a door so this is what it will look like till tommorow . Here are some pics
