im using a DR60, which is only 0.6mx0.6mx1.4m.
100mm RVK fan outtake at top via filter
passive intake
250w cfl
i have no heat issues at all, if anything its a bit too cold, about 70f. about the same as the room ambient temp. ok im not using hps but i think 250w hps would be no problem at all, only issue is limited height to grow the plants under hps (given room for fan and filter, light, and pot).
making sure there is plenty of passive intake (but less power than outtake) is very important, this makes a big difference for me.
these tents have a 3 large grilles at the bottom that can be uncovered by lifting a velcro cover, i use 1 open as passive and works fine. using this makes the tent non-lightproof though. also some light shows through the zip for the door, so i am extra careful about using room lights.
for me the problems are the restricted height (probably applies to DR80 also), and lightproofing issues.
personally if i knew as much when i bought it as i have now learned, i would just convert my closet into a growroom instead of using a tent, and make sure it is properly ventialted. thats what i intend to do for my next grow.
i guess though if you dont have the option of doing a diy job with panda sheeting or mylar then tents are a great way to get started.
oh i forgot to say, someone was asking if you can vent into the room you also vent from. Yes, this works OK, but is just not ideal. I have had no problems doing this, although i do keep the room door open mostly (i dont mean the tent door), to ensure that air circulates outside of the room as much as possible.
