What I'm planning on using (suggestions needed) Tent: DR80 Grow Tent 2.7ftx2.7ftx5.3ft Lighting options (Is 400w too much for that size of tent?): 250w/400w Lumatek Digital Ballast 400w MH (vegetative) 400w HPS (flowering) or T5 CFLS 8x24w = 8000 lumans at 96w Ventilation and Odor Control (Will this be enough to keep the temperature optimal while running the 400w bulbs?) Active Air 4" Inline fan Can-Filter 2600 4" 94CFM Passive Intake Small oscillating fan pointed at plants
that setup will produce some delicious tree man. just gonna need to get some more fans in there for circulation. i think if you stay under a 400w it should be fine to keep cool. but buying another vortex will never hurt! Edit: get the 6" fan with a fan controller youll like it much better its much quieter when turned down and its the same power.
Thanks man, so you don't think that fan and filter will be strong enough to keep the box cool enough?
The combo you have will work well with the T5lights and may work fine with a 250W, but if you do step up to the 400W it would require a cooltube to remain cool enuff. The fan combo you have will prob work but a larger 6" set up will work better and not have to be runnin full out all the time. Running the larger one with a controller would be the best route and quieter than the 4" and maybe cheaper on the elec bill too.
come flower time i think so, as lights are only on half the day, but it will be more then enough i think. if math is correct like it usually is. you should need 2.7ftx2.7ftx5.3ft=38 sq ft. 38*5=193. (want to clear air 5 times every few minutes) add carbon filter multiply that by two. 193*2=386. which a 6" should do fine.
Thanks everyone for the help Do you think the 400w would be worth it? Or would a 250w produce just as good? The entire 400w setup will cost roughly $1000, I haven't calculated the 250w setup but it would probably be a few hundred dollars cheaper. New setup Tent: DR80 Grow Tent 2.7ftx2.7ftx5.3ft Lighting options 250w/400w Lumatek Digital Ballast White Horizontal Reflector 18" 400w MH (vegetative) 400w HPS (flowering) Ventilation and Odor Control Inline Fan (Active Air) 6" 400CFM Carbon Filter 50 400CFM w/ 6" Flange Fan Speed Controller (15amp) Small oscillating fan pointed at plants Does this setup now seem balanced?
I run a tent that's 2x4x7ft w/ a 400w mh/hps, cooltube cooled by a 6inch inline duct fan from HTG supply. At the top I use their 4inch fan and filter combo that's 170cfm w/ a growbright filter. I also use a 16inch oscillating fan to keep wind on the trees and cool the bubble buckets. Works pretty well. Check out my grow in my sig for more specifics!!! Best of luck sir!
Would this fan/filter combo work (Bustan - Toronto Hydroponics Grow Lights Nutrients Hydroponic Supplies Canada) or do I need to spend the extra $100 and get the 6" 400 CFM combo?
When a filter says it has a 6" flange, does that mean it wont work with a 4" fan? Would this filter(Bustan - Toronto Hydroponics Grow Lights Nutrients Hydroponic Supplies Canada) work with this fan?(Bustan - Toronto Hydroponics Grow Lights Nutrients Hydroponic Supplies Canada)
im trying to figure out how/what to equip a dr80 too. they have 5.1in-130mm intake & exhaust holes. thats a prob w/6in ducts. gotta get a reducer or something. I figure 400w mh or hps is ok. i was lookin at this fan/filter combo. cheaper and more flow than what yer lookin at. wonder how much less flow w/reducer? 6" INLINE FAN CARBON FILTER COMBO ODOR CONTROL (UL)CERT on eBid United States this reducer might work.

I'm currently in the process of http://forum.grasscity.com/grow-room-design-setup/674008-600-watts-too-hot-my-4x4x7-tent.html dropping 1 of my tents. In hindsight I'd rather have just grown in the closet, the tent is restrictive it makes it hot traps heat. I'm running a 600 watt and a 400 watt in that closet now and my temps are currently the same or lower than just the 600 in the tent (still have optimization to do).
