So i have a vertical system, with 3 600's in cool tubes stacked on top of each other. Air cooling wise, its awesome. I have a fan above them sucking outside air from an intake in the attic. It is then pushing this air though them, and then finally another fan pulls it back into the attic.
This room is completely sealed, with just the lights being air cooled. Co2 is added to this room via a bottle. There is an a/c box with a 5k btu to provide cooling, but so far it barely every comes on. RH in the room runs about 60-70% during lights on. There is insulated ducting on everything in the room (that was my first thought, and although it helped, its still not nearly enough).
My problem is the high humidity outside. I run my lights at night when temps are lowest outside. Unfortunately the RH outside (where i pull air from) is also the highest around that time. Usually 60-90%. The temp is super cold usually, like about 50F.
All of this come together to form a high humidity micro environment right on the cool tubes themselves. When the air is on, there is a shitload of condensation on the oustide of the glass for all 3 cool tubes, although the closest to the fan is worst.
When i say a lot, I mean the entire cool tube is covered in water droplets, to where i can't see the bulb inside. Now luckily its all on the outside, so I am not too worried about this starting a fire. My main problem is that its covering my nice 600's, and therefore blocking their light output.
So far, the only solution I have come up with, is to plug my intake and exhaust fans into the same thermostat as my a/c. This basically runs everything only when the room heats up. This is working for now, but I'm sure that in the summer with higher temps, it won't hold up. Cool tubes are supposed to be constantly exhausted, in order to keep temps low. I've even tried slowing down my intake fan, by way of a dimmer switch. This also helped, but also at the cost of heat.
