My final tent setup. check it out

Ok well i put tons of reading and what not, but its all here now:

HTG S GROW TENT 20 x 36 x 64 (in closet)
WATERFARM (6) WITH resivor and controller
400watt digital ballast w/ hps bulb and MH conversion bulb
cooltube reflector
ELF cartoon filter w/ 4 inch inline fan (170 cfm)

Have the cartoon filter then fan then ducting to cool tube then ducting to attic for venting. let me know what you think. ventilation not ordered yet

Sounds good man just not 100% sure that 170 cfm fan through, say 5 feet of duct and a carbon filter will have encough cfm left over to cool you cool tube suffeciently.. I am interested though, hopefully one of the resident experts can answer this..

im thinking i might just go carbon filter inline fan ducting and out the attic. then just have ducting from outside the tent to fan cool tube and out the attic

I think that would be best too thats what i did as well as you can see in my thread. Basicall the same size as yours.. Plus in the future it opens up options for C02, raising temps (better control in case you ever move tent to cool area) etc. But before you throw down the loot I would wait and see a few more opinions.. Board is usually pretty busy on the weekends from what I have seen.

well i have everything but ventilation. got a killer deal from a fellow grower. now that im looking at it the tent has 2 5 inch holes and the cooltube is 6 inchs. how the hell did he pull this off

You can get a 6" to 5" reducer anywhere for a few bucks. With the CFM you will be pulling..that 5" inch is fine...

Sounds like your on your way.Use a reducer to make the hose 5 "..I just grabbed 2 new 4x8 tents greta deal $150 each new shipped and slapping 2 tables in them 1 4x8 table in each,2 600 watt lights in each,co2 tanks,grabbed 4 new 250cfm fans for $15 each,4 carbon filters $10 each new and then 1 550 cfm hydrofarm fan with a larger 6x24 inch carbon filter for $55 new to add even better odor control.Tossed in 2 clip on fans to move the air inside each tent and gonna use 6 inch square pots to grow in thinking 40 per table.Ill keep and eye on yours and see how she goes and Ill be posting these setups shortly for a journel.Good luck and try the reducers to fit out the vent holes

sweet man cant wait should have journal soon
