Thanks very much! I will get the cool tube

I have tried without one and it's too high but will having a cooltube duct to my exhaust cool things more? (no fan blowing onto the bulb)

Air cooled hood would be too expensive for me so I need an alternative such as a cooltube perhaps but I can't find anywhere an answer to my idea which is why would I need one if my exhaust should pull the heat out of tent anyway? Will it actually reduce my temperatures even more if I duct the...

A filter? Like for smell? I don't really mind about that, not yet anyway. Yeah.. but I still don't understand the need for the cooltube then because doesn't my exhaust just pull the heat out of the room anyway?

How does the cooltube even work? Isint that the same as having no cooltube? just the extractor pulling hot air from the grow room out? Or do i actually have to put a fan pushing air onto the bulb with the cooltube? So confused.. Do I actually need a fan blowing through the cooltube to cool it...

So a cooltube needs an exhaust.. I really am confused how it works.. I have an exhaust fan at the top of my tent, can I just attach it to the cooltube with duct and then will that cool both my tent and the bulb?

I was just thinking.. If my ambient temperature in the grow room with all fans on (So 2 fans and an exhaust fan and no light on) is 35 degrees celsius then even a cooled hood would not help lower the temperature (because my temperature is already way above the optimal temperature (28 degrees...

Thanks for all your help bro! Same to you!

I can't vent the air outside my room but I heard insulated ducting can quieten the sound.. Do you think I should get some insulated ducting just to help quieten the sound? Will that work? (I really can't vent anything out of my room) and so an air cooled hood should be all I need to get good...

I am so sorry buddy! I only just saw it now, for some reason I couldn't see it before! That really is extremely helpful my friend, thanks so much

How much will that lower my temp by? Would I finally be good to go after that? Also is there a way I can lower the sound of the exhaust fan? xD

But yeah it's like 47 degrees celsius with the fan off and 42 degrees celsius with the fan on.. hardly much difference.. So what do you think I'll need now? It really is rediculously hot where I am at the moment, it's never usually like this at all

My exhaust fan is making the rest of my room (outside the tent) cooler, I have it at the top of my tent (in a hole) and pushing air outwards.. I was wondering if maybe using it as a fan pushing air inside (instead of pushing air outwards) will just cool everything down inside the tent.. Would'nt...

Thank you so much for all the information! That's really helped so much! How much would a cool tube lower my light temperature by? Also how many lumens would I lose if I used a cool tube?

It's only recently become really hot because of it being summer

It'll be in my bedroom which has a temperature of 31 degrees Celsius

I'm getting like 40 degrees celsius without the exhaust fan.. How much will the exhaust fan reduce to temperatures by?

And what should I use to attach the fan to the hole in my tent ceiling? Also do I need to vent it out of my room?

So I can't use an ordinary desk fan? How much CFM should it be for my conditions?

Yeah that does make sense actually.. Do you know if I can use a regular fan as an intake fan and/or a regular fan pointing out my room as an exhaust fan?
