Hello! I want to create a greenhouse for flower seedlings. I live in Orenburg. Greenhouse 6.5x10 polycarbonate. Will only subsoil heating be enough and what should it be?
My underground heating is done with the help of pipes through which hot water flows. The laying depth is about 5 centimeters deeper than the insert. And most importantly, in order not to heat the whole earth around the pipes, make a screen. I have it with halves of PVC pipes of large diameter cut lengthwise, with foil laying along the contour. This will save you a lot.
