400w Grow Tent, Please Help

Hi everyone, I recently harvested 2 lowryder #2's and although i was throughly impressed because it was my first grom and i actully got extremely fire bud to smoke. But anyways I am thinking about upgrading systems. I have been looking on the internet and the grow tents are starting to catch my eye more and more since space is somewhat an issue. The thing is i have never used one of these tents and dont really know what all i need to get. Im going to be using a 400w digital ballast MH/HPS and a cooltube hood. Will someone please help me out with what all i need to get for just the tent setup as far as which tent to use for the light i have, ventalation, filtering? Not to sure about hydro or organic but kinda leaning towards soil organics since iv never gone that way. Anyways i have what i think should be plenty enough money to start this thang up, so please yall help a brother out

Also: IM looking at carbon filters right now and didnt know there were so many different sizes and shit. Could someone also help me decide what would be a decent carbon filter for the dark room 100?

Hi.....I have the darkroom 100l (6'tall). Currently running a 4" vortex fan - sitting on the roof of the tent pulling air though a Can33 filter. I use a 600w hps lumatek. I have an air cooled hood, but not using it right now because my grow area is about 60f all the time, so I need the heat from the regular reflector. Temps at 77f day and 60 night (30 % humidity). The fan is on a speedster controller, which I run on low. This still creates enough neg pressure to suck in the walls. I usually leave 1 vent open. I have 4 plants in 3 gal. pots bushy supercropped and fimmed ....vegged under floros for 2 months. 3rd week flowering right now, no smell in the exhaust (which keeps my basement warm)

These secret jardin darkroom tents are great quality...really nice zippers and stuff. also lightproof. Ony comparible to growlab imo.

also I'm doing an organic soil grow....promix/perlite/vermiculite...all botanicare nutes incl. liquid karma and sweet...I get good results with this setup and I like soil cuz its easier for me than hydro

Ya i figured it wouldnt be as much up keep as the hydro and still get excelent product. I was maybe trying a coco grow.
