well to be truthfully honest...yest the frost WILL ruin her...basically all you need is some panes of glass wich are big enough to surround her completely and rig it up so that no frost can get to her...kinda like a glass box! it should..in theory at like a greenhouse and hopefully keep temp up...but with saying that you must keep humidity down..i repeat MUST otherwise you will have mould growing on your buds!!! hope this helps you out!
