Hi Being very new to gardening ( 2nd year ) and just bought my 1st greenhouse I am hoping to try and grow some flowers and easy veg from seeds. Living in the south of scotland I know I will need some kind heat to protect from frost , from feb to may . Can anyone advise a paraffin heater that they use for frost protection , and any other tips for using a paraffin heater or not in a greenhouse. My greenhouse is 8ft 6" x6ft 6" . Looking for a make , model that would suit ,and where to buy. Thanks Mike.
