So in a nutshell i will start to up the store of tinned food and everything else including the MREs and im gonna see what i can do about the heat for the greenhouses, night have to get a bit inventive on this one

I was looking into your greenhouse heating predicament and came across this:

Compost keeps at a constant state of 40C if properly done. That in combination with a few of these:

A 200W solar panel could easily run two of those heaters with energy left over for night time.

It depends on how insulated the greenhouse is too. Maybe replace the panes with these:

Using water bottles to heat a greenhouse:

Not sure how good that'd be, but I reckon it'll be a multi-method solution. It might help if you painted the bottles black too, as that absorbs heat.

I suppose it depends on how much ££ you have to burn on this project.
