A 1000 watter in your small dimensions of your grow area is overboard. You would run into uneccesary higher electricity bills not to mention dificulty keeping that small space cool not unless you run a air conditioning unit. For that space a 250 watt or 400 watt would be ideal.Hi I got a Buddha tent 1x2 1x2 by 2m tall . I got 1000w in there is that to much light stress ?
