DR60 and 400w HID

Hey guys I joined a while back and haven't really been active, due to some drawbacks. I haven't grown any dope before and I am fairly uneducated about marijuana growing.

Anyway my question is, will I have heat problems with a 400w dual spectrum in a dr60 grow tent, with a cooltube and a strong extractor fan?

Tent: dr60 (60x60x140 or 2''x2''4.5'')

is the extractor fan strong enough to keep my temps cool or shall i just stick with a 250w HID? I am planning to put 8 plants in the room @ 6 liter pots.

I think it should cool it fine.

I use a small 4 inch fan on my htg cool tube 400w, it keeps it just right.

Thanks for the quick reply. Also the cooltube being 6'' and ducting being 5'', would that be a problem?

No I just used gorilla tape when I had that problem and sealed it up.
Easy to tear down if need be, and cheap.

Alright , thanks for clearing that up champ.

Hopefully, in a couple weeks I will have everything set up. I am a bit anxious as it is my first grow, hopefully I won't mess things up.

Ya with a 400 everything should go fine

Hey man how are you finding that 400 in the DR60?

I'm getting a DR60 as well and can't decide between a T5(2ft 8 light) or a 400MH/HPS with dimmable digital ballast.
