So it seems that folks are worried about citrus trees in greenhouses? This is my concern because I am hoping for a lemon tree in a big pot in the
greenhouse I am building. Is supplemental heat the concern? or, is it cold ground that that is the issue?
I have an aquaponics setup that I am installing; I decided that I am going to enclose it with a
greenhouse so I do not have to harvest all of the fish (Tilapia) before freezing temps each year. I have considered heating the
water with a
solar flat plate or an evacuated tube
solar collector and hoping that the ambient heat from the 300 gallons of water in the tank along with the water running through the grow beds and sediment collectors will be enough passively warm the
greenhouse enough at night without any additional heat inputs.
Is there a minimum winter temp for citrus trees? Is there a minimum number of winter daylight hours needed for citrus (Lemon)?
This was an interesting
thread to peruse. Thanks
