heating small greenhouse
Just wanted to know what you think.
I have a 8' by 12' greenhouse with 4 tier metal racks. They all have 40 watt florecent lights on them. I have 32 lights with 2 40 watt bulbs each, so 64 bulbs. Anyway they are keeping my greenhouse arount 60 to almost 80 degrees warm. It's preety cold outside, 35- 45 degrees. I had a electrican do the wiring,it's grounded. I use extention cords though.I still wonder how safe it is with the moisture in the greenhouse. I try to be careful when I water. The electrican seems to think I'm ok. Any thoughts?
