Two weeks ago the local allotment had their annual plant sale. They said
the beans and tomatoes were not good and they had none for sale and to
come back in two weeks. Yesterday on visiting again they had hardly any
on display.

They said the problem was the weather being so hot, that the poly tunnels
got too hot, and opening up the tunnels at each end was not enough to
solve the problem.

What struck me was, that if you covered the tunnels with old blankets or
rugs or something similar, would that not cool the tunnel down? Since
it's the effect of the transparent plastic that is responsible for a lot
of the heating effect, i would have thought?
We had ours out on the patio for weeks, hardening off and growing well,
planted them out yesterday (with flowers). Why didn't they simply move
them outdoors? Unless you are in frosty part of the UK.

This was on an allotment. Would excessive sun and heat have 'done for them'
in the poly tunnel, if they had been properly watered i wonder?
