They are nice and work but... They are expensive and floros are not the best spectrum to grow under. They are just not intense enough to get big bud growth if you are growing for personal stash you could get by with one but dont expect the results you see other people on the net get for alot less money. a small box (for one plant) is not enough for me to justify the price of the units. Build something or modify some piece of furniture and you got a stealth box that will work better and i bet you could do it for under 500 dollars. I would grow under a 250-400 watt HPS light but thats my preference. Good luck with your decision
