@bono420, specialised mylar canvass should be fine, some materials are "too reflective" for plants if that makes sense, but yeah a closed space without enough exhaust will raise the humidity, what you're going for is actually VPD that's optimal for veg so something like 0.8 and over if I remember correctly. Look up VPD, see for yourself. ๐
