Which? This Attic or a Bud Tent ?

Heres the problem:-

Summers comming, my RVK and filter are working there arse off, this years going to be hot and I have included a picture of my attic to show you my situation.

Lights:- 1x600w HPS on a rail/light mover
1x600w HPS at the right hand side
1x400w HPS at the front of the rail, (u can't see that 1)

Area:- 6ft 6'' x 4ft 6''
plants:- C-Mass+Powerplant+OrangeBud+Skywalker+DurbanSkunk+Jo rgesDiamonds+Jack Herer+Shiva Shanti

Ok if I brought a BudTent measuring 2m (H) X 2m (L) X 1.2m (W)
would that be a better grow location than using the attic?
Considering what u can see in the picture surely the Fan and filetr would be better accomodated in the Tent?

If i grew in a bud tent would I get away with just the 2x600w lamps on the rail and thus cheapening up things by getting rid of the 400w lowbay? or would this be reflected in the yield due?

Im pretty sure I'd have a better reflective enviroment in a tent, certinaly easier access..

I usually clone and they hit no more than 18", these are seed grown and i didnt wanna top em too early, (I always believed Feminised seeds are more prone screwing up if stressed). Its the first time ive grown feminised seeds (Dutch Passion ones), so I left alone and they shot away, Been topped now tho, lol.

your advice is much needed folks, even if u tell me what your yield in that sized tent is, or any sized tent...Please give all specs u can or can remember, thankyou

have you grown in an attic before? temperatures fluctuate wildly. on a hot day attics can get to be like 140 degrees without proper ventilation. if you can control temp in your attic youll be fine, but im going to guess that you wont be able to since you said it gets really hot and summer is forthcoming.

the two 600's sound like they will work very well in that tent. youll definitely be able to grow some happy monsters in there. it looks like you dont have anything to reflect light in your attic so im thinking the grow tent is the way to go.

I think your bang-on the money dude, Grow tent just seems to be the way,the attic is double lined with mylar, I opened it up so i could stand bk and take a pic. Cheers...
