Yes, plastic will cause condensation = bud rot and mould. I guess you could try a blanket of horticultural fleece at night. If they are in pots you could also insulate those with bubble wrap. I had to put some of mine in the open, after my PT got too crowded. I'm leaving them to thier own devices and see what happens.
thanks for ur reply took plastic off no bud as at yet doin prity much the same as u and leavin them to there own devices
