Edinburgh temperatures are due to abate for a day or two (with even the promise of double figures tomorrow!!!) before another spell of nigh time frost threatening again. I took the opportunity to clean the greenhouse glass this morning, because a paraffin heater keeps off the frost but the payoff is a coating of soot on every surface. After three or four nights the greenhouse looks more like a blackhouse and light levels are markedly lower. So I have emptied it out and given the windows a good clean. Not having any covering lid these cauliflowers are decidedly mottled with a film of smuts! They are out in the fresh air and sunshine today.
Fleece is wonderful at trapping smuts! I won't be reusing this bit.
Never thought of the heater being smutty.
