If you have a room to put a tent in, then save your money and just use the room. If you plan to do the number of plants that syst holds then it might be a good buy but if only doing a few then save your money there as well and dump it in digital ballasts/lights, fans..etc. Best thing you can do is read, then when your done, do some reading. lol Look through the hydro section and research, research on systems others are using, their benefits and how that applies to your situation. Many, including myself do ALOT of DIY so reading there will end up the best friend you ever had.
