Hello,
I recently modified my ventilation system to pull air in from outside using an attic duct, loop into my grow room to cool my lights, and out again through a different duct in the attic. The tubing is 6" and the fan on each attic vent is an 8" suncourt that is reduced.
The length of ducting that pulls in cool air is running into major condensation issues. I live in Seattle where it is often cool and moist outside. The entire length of ducting coming to the 1000w lights is acquiring condensation, which is dripping all over the place. There is no problem after the lights (Naturally since the lights super heat the air).
This is of particular concern in the attic where it is cool and condensation is forming over the ducting and ventilation fan (The one pulling in outside air). I went in the attic to take a look at the ventilation fan and it was very wet on the outside. I was touching the power cord slightly and it seemingly shorted out the surge protector that both fans were connected to. I was unable to power them back up again using the same power cord, or the surge protector. However, they do still start up when a new power cord is introduced
What's the best way to resolve this?
Should I get some insulated 6" flexible ducting instead?
How can I safely run a fan that is subject to condensation without any power or fire risks? Can I just wrap it? Is there a special fan recommended that would be safer to use?
The water just appears to be on the OUTSIDE of the ducting, and I can't feel any inside. Do any other growers just let this occur?
Thanks!
