Heated propagator

When looking at propagators, I decided on heat mats instead, as I wanted something more flexible.

I bought mine three years ago, and they're as good as new.

I just use a heat mat now, too. The thermostat in the Stewart propagator conked out and fixing or replacing it would be too much of a faff. I have that BioGreen propagator too but never use it because it's too big and power hungry for my needs, and I don't have power in the greenhouse. 

This is the one I have - https://www.amazon.co.uk/Komodo-Advanced...B00B99OU9S - it's just about big enough to fit two 4/6 cell module trays or half-seed trays on, which is fine for me because I germinate everything except sweet peppers and chillies on a sunny windowsill. I plop it in the bottom of the Stewart propagator and plug it into a thermostat like this one - https://www.amazon.co.uk/RIOGOO-Thermost...B07Y52KPKN.
