Problem comes after first rain in the fall, night humidity levels hit 80-90% at night. Propane isn’t enough for me to lower my humidity at that point so I either continually run vents or dehumidify.
I am learning so much from this thread. Thanks Redlaser for the info.
What is the size of your greenhouse ?
What heater are you using ?
Do you have an idea of monthly fuel cost?
I am only planing on a summer grow looking for small plant count larger weight/plant.
