Would like to have some feedback on anti condensate poly plastic for greenhouses in humid areas. Would like to know what has, and hasn't worked for you for keeping humidity down and keeping condensation down. I will be installing vents on the west side of the GH, and big vent fans on the East side pulling fresh air from the west vents through the GH and out. Im trying to avoid condensation build up where it may drip off plastic onto vegetation.

1. What has worked/hasn't worked for you?
2. Specific name of company/6mil/3mil poly/website?
3. Have you ever sprayed a wetting agent to reduce condensation build-up? Did it work?
4. Also suggestions for black-out tarps that have worked well for you, trying to avoid spending big $$$ on breathable tarps. (I know i'll acquire some condensation when doing the light dep without a breathable blackout tarp, but the month i'm doing light dep isn't usually a rainy month (july).

i am at 7200ft outside telluride i am using thermal inrared anticondensate 6 mil from greenhouse megastore. i also have used farmtecs plastic and it is close to as good . the anti condensate just keeps the drips rolling on the plastic it helps a little . but the real story is good greenhouse management pratices and a good weed blocker to keep unneeded humidity out of your zone.
i use cheap "panda" film for blackout but have been eyeing the 14 mil b/w breathable trilayer. from farmtech.....
having a dedicated inlet for air(i dig mine underground) is the best IMO for humidity at night ...

what do you do specifically underground? Bury ducting in ground, have it come up and into the GH connected to an inline fan so the air is cooled a little before it comes into the GH? or do you just shut your normal shutters that are pulling air in at night, and just have air being pulled in from a tunnel underground? how deep did you go?

yes dig a U shove in 6" ducting and shoot air thru it .... will put up pics of mine tomarrow.
yes look around some might find it for cheaper eleswares not sure. i like that company...
