Already having heat problem with cheap COB

[No1up]

I have a cheap COB light I'm using until I get my 315 CMH but the COB brought my temps up in the 3x3 tent by 10F. I'm now wondering if the cmh will be worse. Did I make a mistake? Should I just get a timber grow COB system of better quality or a QB? I really don' want to run a ducting system.

Save your money and by a inline fan with ducting and carbon filter. You can spend all the money you want on a light but it ain't gonna do shit if you don't have proper airflow.

 

[No1up]

I have a 4" fan/filter I haven' installed yet. Do you think this would make a diffrence? My cmh good is not ducted.

 

[Chef420]

What dubekoms said. You’ll have to vent and scrub your air. It will stink. You’ll also have too much humidity building up without ventilation.

 

[No1up]

Will the venting help even though it's not an air cooled hood?

 

[Chef420]

Definitely. That will be your only way to cool the tent. I ran a 600w hps in a cooltube in my 3x3. Temps were still above ambient. (My garden is in my bedroom)
I just recently switched to 6 vero cob kit (300w) and it produces almost no heat. But I still need ventilation.

 

[Chef420]

What are the temps like in the room? Is it your bedroom?

 

[No1up]

70F light one om 84f, light 2 on 95. No vent installed (yet). Small fan running.

 

[Chef420]

84 is about as high as you want to go. Higher temps bring all sorts of issues.

How are you liking the cobs?

Bro, youbgotta exhaust the tent no matter WHAT light you use. Also, bring in new fresh air. And to answer your question, the CMH will be triple the heat problems you're having with a cob light. You can guarantee that.

I was afraid of that

LOVE the cobs. So far the biggest difference is temperature. I’m almost starting to flush my first run and they look great. I have better coverage/penetration with 6 cobs rather than one bulb as well.

LEDs in general are just so PogChamp. I fuckin love the tech. Fuck HID.

The name of this thread should be changed to:

"Already having heat problems without exhaust"

Once you get some air flowing properly, temps will become manageable.

Lighting system does not matter for heat, only thing that matters is the amount of watts you use, 1 watt = 3.41 btu.

Where the hell are you getting your info from bro, watts are the only factor for determining heat, if that cmh produces 3x more heat it uses 3x more watts.

Yodaweed, would you not he able to use less power with the QB to achive same results there by lowering heat?

PogChamp? What does that mean?

Correct. All lights make the same heat per watt, but a QB will produce the same amount of light with fewer watts.
