For the first time ever, on advice from chums here, we're growing some in long, deep trays of compost outside in a sheltered, sunny area, with a brick wall close by which never cools down, like a night-storage heater...
So it's 'Minibel', and 'Apache', out there, with a few toms for company!
I'll keep a couple in the GH just to be on the safe side though...
