I built my own utilizing a metal storage cabinet so it is totally stealth. Total cost including materials, 600w light, fan can fan and filter, drip system and all chemicals needed to grow from veg to finishing flower .... $1500 and worth it. I am able to lock it and no light escapes at all. The internal temp has been running around 75 degrees and to drop the water temp I am using frozen 1 gallon water jugs, I also just added an aquarium air pump that I found sitting around which will help oxinate the water.
