Hii,
I live in the south of Iraq , I have about 300 tilapia (small ones ) , The winter is relatively cold over here ( may be the temp will as low as 5 degree centigrade , may be lower ) , I am thinking of building a home made greenhouse , I am asking about the temp this greenhouse will provide , and how efficient it will be , I mean if the temp is example 5 degree Centigrade , what will be the average temp inside the green house .
Best
