Warming up an unheated greenhouse

[greasyfire]

I have baught a small plastic unheated greenhouse, does one for 12.99 and i am wondering how to keep it warm. Coming up to winter it is no hotter than outside unlike in the summer when it was an regurlar 20 degrees. I am wondering what methods are used to keep it warm or hot and what are ideal plants( fruit and veg) that can go inside there. The current method i am using which only laqst for 5 minutes is a bucket of boiling hot water.

A cheap way is to light a candle under a metal bucket!

Hello Greasyfire, you can't really heat your placcy greenhouse the way you can with a more conventional type.
What it will do for you is shelter your plants from wind and rain and provide a bit of protection against frost - especially if you put a bit of fleece over them inside the greenhouse.
I'm growing winter lettuce, Pak Choi and Pea Shoots in the cold frame and they're doing fine but you might be a bit late to start them off now, but you will be able to get things started a little bit earlier in spring.
See what other suggestions you get.

What do you have in there?
Mine are unheated plastic blowaways too: I have ... not much in them over winter, but they are fine for bringing on hardy crops (leeks, onions) a bit earlier in the new year.

Work with what you've got.

I bring tender things (chillies, fuchsias, pelargoniums) indoors for the winter.

I had bamboo, chayote and other tropical things but i took the out, now i have a aloe vera, potatoes, onions and cactuses. My house and shed are jam packed with plantsuntil i find a new way of heating me greenhouse. But i want to start some crops early in there but i still need heating.
