Greenhouse - Sweet Peppers

Today I popped into the Greenhouse and have found there is a problem with the Sweet Pepper 'Summer Salad Mixed Seedlings' which are in the heated propagator. They appear to have been burnt on top due to the sunny weather we have had recently so I will now move them out of the heated propagator and take the dead pieces off and hope they will grow out from the leaves. I have also noticed that the Cauliflower 'Cheddar F1' Seedlings are also looking slightly burnt so have watered these and hope they will pick up.
