Note that one is allowed to grow within a locked, secured greenhouse. However, there are no specifications as to the construction behind such a greenhouse- just that you must be able to lock it.

CU05: Can cultivation be done in a greenhouse?
Cultivation must be done in "an enclosed, locked facility." A greenhouse is included in the definition of "enclosed, locked facility
". However, to meet the definition of "enclosed, locked facility," the greenhouse must be equipped with "locks or other security devices that permit access only by a cardholder" or surrounded by "solid 10-foot walls constructed of metal, concrete, or stone that prevent any viewing of the marijuana
plants, with a one-inch thick metal gate."
From this, a PVC frame with polyethylene plastic sheet would do, provided you had a chain with a padlock that secured any sort of door: enclosed, locked. Consult a lawyer; see what they think.
Any greenhouse will be impossible to secure in a fashion that assures the same security as 10' stone walls with inch-thick metal gates; it's ridiculous. Glass will break, polycarbonate can be cut or burned, and fiberglass isn't much more of a challenge either.
