Spuds in Greenhouse for christmas??

[Pieman]

I got the charlotte seed spuds out the fridge last weekend left in them in the garage by the window for a week and planted up into a 40litre bag on Saturday - will keep them outside as long as poss with out the temperature dropping too low then into the greenhouse.....

Must have a look for a paraffin heater now - (will start a new thread if needed).
