Just an up-date on my heater decision...the last few nights have been 28-30 degrees outdoors. Putting my little Mr. Buddy propane heater on around 9pm when it is about 38 outdoors, on low...4000BTU's, the GH temp is staying around 47 degrees. Actually this is just about what I had planned for it to do. Around 7-8 am I shut the heater off and the sun quickly warms the GH to the 50's, 60's, 70's, 80's !
Only the heater is inside, connected to a 20lb tank with a 12'hose. It shuts off at the tank, so I don't even have to open the GH up and let the war air escape. I do leave the lower back vent open for air.
Right now, the brugs are budding and blooming...but I don't know how long they will do this.
