Varieties that tolerate heat
I'm looking for some suggestions. Where I live my growing season is not long enough or reliably warm enough to grow tomatoes outside, so I grow in a greenhouse. The problem is as a result I have to watch the temperature and make sure it does not get too hot inside the greenhouse. I keep the windows open and have a fan set up to circulate and cool the air, but sometimes the temps do get too hot. I am looking for suggestions for indeterminate varieties that do well and set fruit reliably in hot temperatures. I had several plants this year that did not set fruit (Aunt Gerties Gold, NAR, Pineapple) and I think it was because it was too hot when they were in bloom. I have some vents where insects can get in through and I give the plants a gently shake almost daily to encourage pollination, however some plants just did not set fruit.
