Thinking of making small plant house/greenhouse to use for seedlings and growing on so as to free up the main Greenhouse.Intend to use clear polycarbonate for the sides, is it ok to directly affix to the timber rather than use the plastic fitments that are too expensive?

Thanks for your reply.I have read conflicting reports about the polycarbonate expanding,I maybe I am a bit overcautious .
