Lights getting hot

[Jacare]

Hi guys,

As some of you have probably seen I just got a HLG quantum board 135w.
I after been in over night I checked it this morning to find the temp had risen to 36 degree Celsius!
Obviously I was amazed and tried to strategically place my fans point at the driver. The fans have been put on full power.
What else can I do to avoid overheating?

Just checked, it's at 34 degrees again!

Hi jacare, do you have an extraction fan running taking warm air from near the light and refilling it with cooler air from lower into the tent?

What temp is it outside the tent?

 

[Jacare]

I have a 4 inch extractor fan and carbon filter setup. I've been advised that due to the small size of the grow that I don't need an intake

Hmmm There's got to be a simple way to get the warm out and cooler in. Are you on a tent?

 

[Jacare]

In a tent which is in a cupboard

Ya, I'd try to move some air and see if temp comes down a little. A few degrees might help.

It's so frustrating! New light and I got issues! Good job it's just an experiment plant in there right now

Keeps us on our toes. What you experimenting with?

Just a freebie I got before. A regular grandaddy purple. It was doing really well but now it's been exposed to some unusual heat so we'll see. Just glad it wasn't something else

Ok so I've got it at a consistent 34 degrees. Also I made a mistake, it was 39 degrees earlier not 36 degrees.
What do we think? Do you guys think a plant can be maintained healthily at 34 degrees Celsius short term until I can get a bigger exhaust?

Also would it be possible to fit some kind of reducer so I can use a 6inch fan with a carbon filter made for a 4inch fan so I don't have to get a new filter?

I had a similar problem before i upgraded my fan I switched to a 12-1 cycle in my veg room and it helped to manage my temp. The draw back is it might slow down your growth rate but I think its better than the heat stress.

Don't know how electrically minded you are, and not sure of your set up, but is there any way to mount the driver outside the tent?

Even better outside the cupboard as well.

As long as you make a good seal u can use your 4" carbon filter but it will reduce the amount of air your fan is capable of pulling.

Thanks for the reply.
Thing is I'm thinking of flipping it to flower this week, so do you think that it will be ok until harvest?
ATM it's running 24/7.

These plants are tough, that's for sure. You can adapt the size for you needs.

Yeah that was kind of part of my reasoning. Sure it's above the ideal temp but in countries where it naturally occurs it reaches mid 30's.

I had thought about it but there's not enough slack between the driver and the panel and I really don't want to start messing around with it.
