Lighting questions for a grow lab 40 tent.

Im starting my first grow. I have to use the grow labs 16"x16"x55" tent due to compromise with my wife.
Im gonna use cfls for veg and really want a 150 watt hps for flowering for worthwhile results.

my only concern is heat. I can either go with the floralux and and using the 4" flange on top. But with the ballast attached would it be worth the trouble. It also has the smallest deminsions I've found. A sun system would fit but no cooling option.

Htg sells a 150 with a remote ballast, would the bulb alone be managable heat wise?

I'd go led but for over 2x the price for probably half the performance. I've ruled it out.
Any thoughts on the situation?

im thinking i could modify the floralux hood with another flange on the end of the unit, hang it diagonaly in the tent to give room for the ducting on the end, also i could go to my 4"x8" can filter. Thoughts on this?

I would go with the 150W w/remote ballast and use intake and exhaust fans to help control heat.

Thanks for the suggestion. Im gonna go with it. Just gotta confirm that reflector will fit again cause I've forgotten. I eyed the 4" inline booster fans, would using 2, 1 for intake and the other for exhaust sound decent?

That sounds like a plan.

like the above guy said use the remote ballast it will keep temps down, you can try to just exaust the top of the tent and intake the bottom to keep coo; air circulating before trying to mod the hood, if that dosent work then go with moding the hood. a 150w dosent put out alot of heat but in a small room it will get warm

Err... I'd drop in a stronger fan exhausting out and the 4in fan blowing in. Its good to have negative cfms and negative pressure in a grow space. It helps keep out mold and pests, regulate humidity, and the transpiration in the tent too.

so the cheapest 4" exhaust fan with a higher cfm then my 4" booster. Sounds good.

Yup that should do it. Be careful with using a booster though, they don't react well to differing pressure gradients. Inline fans can handle heat and cold and presure influxes very well.
