I guess that makes spez alt right then <| sep |> Yes it would be overkill in a 9 x 10 room . I have this setup in my room that is 10 x 10 and 4 gavita 1000 ' s . I run a Can Fan 12 for exhaust which I think is about 1700 cfm and 2 hurricane 8 inch fans for intakes . I live in a colder area and this does a good job keeping temps between 7585 for 9 months out of the year when ran at night . However those summer months I have to dial back the lights to 600 . The ceiling is 910 feet and the lights are always hung all the way up to the ceiling , but these lights can put up with drywall ceiling hooks , no stud even needed . Some other drawbacks are the space all that ventilation equipment takes up and still sometimes struggle with the temps . but doable . Air cooled hood would be much more ideal , cost less money , and probably run a cheaper power bill because you could run smaller fans less often . I only bought the gravitas as I thought it would be a better investment for long term growing , hopefully be growing in a new place where they ' d be better suited . Hope this helps .
