We will be building a greenhouse and are trying to decide on the type of plastic to use should we use clear or 55% which is less clear. Will peppers grow beneath 55% or should they get clear anyone with any experience in this? Next question if you put peppers in a greenhouse to harden off do you have to bring them back inside and do it gradually like when you take them outside or does a greenhouse afford you the ability to just leave them in it to harden? And which plastic is better to harden? Getting ready to build a greenhouse and gotta buy some plastic.
