I think that would depend on where you are in the world =D and what kind of winters you have.

For me, here in NY, all I really need is a place that gets as much winter sun as possible & to keep the temp inside coldframe (or unheated greenhouse) above freezing.

I've done this with a temporary plastic greenhouse and a small space heater from about February onwards till temps stayed above 45*F regularly.

hookilau - can you show some pictures of your set up? I usually bring all mine in. They are shelved and I have 3 grow lights for them. This year I will have to buy another shelf and at least one more light. I would love to explore alternatives.

Josh, from your other identical post I can see you are also from the UK, please add this after your name via your homepage, as mentioned we need locations to advise on lots of ?'s. It will also depend on what the succulents are, so pics wil be needed too.

deva, I usually bring mine in as well, but get itchy once the holidays pass =D

I don't have any pics available, sorry.

The temporary greenhouse was very very temporary, it was similar to this portable one on amazon.

I ran a space heater with a thermostat set at 50*F and I did NOT water, at all

=D

I also had an outdoor thermometer that I bought at Walmart for under 7$, that had a sensor and separate unit that told me the actual temp.

So I put the sensor on the top shelf of the greenhouse and kept the part that displayed the temp inside. It was just for insurance so that, when I wasn't running the heater during the day, I would have some idea of what the temp was.

The only drawback was wind or snow storms and that's only because it was a portable greenhouse and very light. I waited till the end of Feb to put it up, luckily, most bad weather had passed.

That was the extent of my setup. Rather low tech, inside, I have regular shelves with shop lights affixed to the shelf above in a spare room.

This year, I am probably going to do the same thing except I will be using LED shop lights I saw at Costco.

I'm debating whether or not I should get a polycarbonate greenhouse from harbor freight.

Still weighing my options =D
