vent duct condensation?

[WHODAT]

I'm cooling my lights from air in my attic. The ducting that runs from a flashing in my ceiling to my lights has water constantly water onto my plants. How can I correct this problem ? My humidity is 66%.

A drain line long enough to reach outside.

I thought flashing was the metal band that runs the outter limits of the roof ,,,were the gutter goes. I am confused. Sorry.

insulation - it will stop the hot air/cool air contact and prevent condensation. We had the same problems w/ intakes.

A simple drain as the chef mentioned will help tremendously also.......

Thanx Jmansweed. Is there a specific type of insulation for 6" ducting?

you cant use cool air from the attic and bring it to the grow. Anything that is kept cool by that cool attic breeze is going to form condensate. Good luck and find a way to cool that light, try pulling from the grow and venting the heat to the attic yeah?

they make insulated ducting, check homedepot.
