Brassica in polytunnel ??

Hi

A friend of ours has invested in a polytunnel and is planning on growing cauliflower / Cabbage in there this year.

I thought polytunnels were ok to start brassicas but it would be far too hot all season long .

Any thoughts ?

Yep way to hot. I start some cabbages, kale and cauli's in September and then plant them in the polytunnel in October.
