48' x 48' Tent 1000w Hydro Set up Advice??

Hi,
I have a 48' x 48' tetn and a 1000w HPS (dimmable) Not aircooled / Should I upgrade? / Do i need another Fan apart from the one that scrubs?

440CFM with scrubber.

What about this system?

You're gonna need an aircooled hood if you wanna try to keep that tent anywhere under the temp of hell, lol. You can get a cooltube really cheap ($40ish). Then just vent it inline w/ your scrubber. Like carbon filter (mounted next to the ceiling to get warm air) to the cooltube to the fan blowing out of the tent.

that system gonna be a bitch your gonna have to mantain all 4 buckets individually. i would suggest 4 site ebb and grow. and you will definatly need to cool a 1000 watt. keep your ballast dimmed for the summer months. another reason you dont want dwc in that tent is water temp. get a system that you can keep the main res out of the grow area so your res solution will be kept cooler.

48 foot by 48 foot? think you need more lights!
