You can still be indoors and be in a wet location-- 300.9 does not say outdoors I did.is a greenhouse considered outside
I thought greenhouses were to maintain a constant temp and humidity? Id hazard a guess you could let the pvc sit in the hothouse to expand then install it, bringing it in cold probally wouldnt be ideal.PVC is a recipe for disaster in a greenhouse, fyi. Too much of a temp swing is going to cause the conduit to self destruct within a few years. We had a thread on greenhouses a couple weeks ago. You should do a search for it.
