I heard the cool tubes weaken the light ray..

So do you think I'll need an air cooled hood or just a cool tube?

Niceee okay I guess I gotta buy one of those then.. I really hope this all works lol. But when I did the calculations of room size and the watts of my bulb It works out for me to only need to use like 120cfm.. Isint over exhaustion bad? and would I need to vent it out the room or something? I...

How much will the cooltube lower my temperature by?

My bulb smashed so I'm waiting for my new one, should get here tomorrow. Should I still buy the exhaust fan with 120cfm?

They're pretty expensive.. Do I really need them? I already bought a reflector.. Would'nt the exhaust lower the temp? Is a 120 cfm exhaust fan okay?

Do you think 210 m3/h would be enough for the exhaust fan?

Also how do I attach the exhaust fan to my grow tent hole in the ceiling? Duct tape or something? Not sure if that's going to work..

Not too sure what you mean by open fixture or air cooled my friend.. I have 2 holes at the bottom for passive air intake and I do have a fan attached to a hole (so I guess that's an active intake). How should I cool the room down more? Does it really matter? I havn't installed the exhaust fan...

Although thats just with the 2 fans turned on and no exhaust

The temperature in my grow tent is 82.4 Fahrenheit without the bulb being on.. Is that okay?

Ah that's awesome.. I'll have to think about that.. If I was to calculate the CFM tho, would that be 1.6 x 1.6 x 3.2 for my room? think thats in feet.. which then divide by 3 is about 25.. so 25 cfm?

That's what I thought haha xD What CFM would you suggest?

Are there any cheaper methods then buying an exhaust fan? Could I just buy a regular fan?

Thanks so much! Where should I duct it too? outside my room?

Yeah that's what I was thinking my friend. I checked how it would look with the lights off and everything and it was really dark in there (hardly any light). Ah that's a good idea.. Could I just use any fan to pull the air through? Like a regular table fan? Hmm.. How much will that cost? I'd...

Nah i havn't yet.. I'm sure it will.. What do you think I could do to help?

Thanks for the reply bud! I have these rectangle holes (2 of them) with a netting, is that okay to allow air through?

Hi I have a grow tent which is Width 50cm x Length 50cm x Height 100cm and will use a 250watt HPS light I will have 2 fans below and above my plant and I'm pretty sure i'll need an exhaust fan at the top of my grow tent. My room outside the tent is pretty warm but hopefully that's not a...
