Greenhouse Temperature

My greenhouse is showing a high of 38 degrees, all automatic windows & door is open.

Anything I should be concerned with or need to do?

If you use thermostatic electric fan heater turn it to fan only

Damp the floor down at least twice per day.
Use roof shading, either net type or coolglass paint on.

The danger when people start to believe their own publicity is that they often fall off their own ego.

At least travelling under the guise of the Pa Snip Enterprise gives me an excuse for appearing to be on another planet

Thanks for the advice Pa Snip.

Went to local “gardeners question time” in village hall last night & asked same question it was suggested old net curtains will do the job.

Going to check out the charity shops for some.

This high temp could be short lived as forecast is for dropping down to 6 degrees next week.

Hardly believable that Colin's above query arrived a week ago - today our greenhouse heater never switched off because the temperature never reached 13C ....... What a difference a week makes.

As an aside on old net curtains I use a large one folded over to spread over the sloping roof of my transparent minI plastic greenhouse cover on hot days. I tuck the ends hanging sown the sides Into a strong strap which anchors it to the wall to keep it steady.

I find that when it gets really hot the plastic cover will otherwise stick to the metal rods of the frame and melt, leaving splits in the cover at the top.
