I have a 6 x 8 HFGH with a Buddy propane heater in it. People on different forums I have read have said that they had one of these in their greenhouse without plant damage. But my plants are having a problem, most especially my tomatoes.
The heater is functioning well, hooked ups to the tank are tight and my greenhouse can't be airtight. I'm not sure how to fix this. Can anyone help?
