Re: What bananas are most heat tolerant?
I can't find anything on the web - but what they did was shade the polytunnel with shade netting and have one end open. Across the open end they hung thick hessian or sacking with water dripping down it, and a fan outside blowing onto and through the sacking. Inside was really cool and humid. For the life of me I can't remember whether they had any ventilation at the opposite end.
