Hi there, can you explain what you mean by an energy curtain? I want to heat my greenhouse this year, and wondering what im in for cost wise.. want to do what i can to minimize heating costs.
Also, if im going to heat the greenhouse.. seems like there are small openings at bottom of windows for condensation to drain out.. however i assume i would lose heat here, is this true? Should i put some foam there or something to prevent heat loss?
Im also going to be working with an inexpensive heating controller from Inkbird. Google it, kinda neat.
