Inflation blower problems?
We just put together an 18x20 gothic shaped greenhouse with polycarbonate end walls and two layers of plastic over the top and sides (attached with wiggle wire/wire lock). The air between the two layers is supposed to be inflated with an inflation blower, however it doesn't seem to be inflating properly. Especially the peak of the greenhouse and closer to the hip-boards seem barely inflated at all. Is it possible the plastic is stretched too tight? Does anyone have any experience with this?
