Heart Breaking

I think this is the problem; very sad. I really feel for you. In many years growing toms in a greenhouse I never got blight inside; outside yes in bad years but never in the gh.

I wonder if you could get a late crop by buying some new plants now, if you can find any. I know it's late but garden centres will be wanting to rid themselves of all veggie plants now.

 

@HsuH I am sorry to see this happened to you. I keep fans running all day long in my little greenhouses because they are small areas. I use solar panels and overhead dc fans on timers along with little "personal" fans which are meant to run from your laptop usb dc output. I also have one dc turbine fan in each greenhouse which is pointed at the vent to help expel the hot air a little faster.

 

Oh yes, see it now, it looks bad.
A real pity, not sure I'd be putting more toms in the greenhouse this year, bearing that in mind.
As they say, there is always next year.
