Greenhouse cooling

[Liz M]

I took the glass out of the greenhouse-door, before I went on holiday, and replaced it with netting. It was during that hot spell and I was concerned with overheating and wildlife getting in the greenhouse. I left everything fully open that I could open and everything was fine when I got back. I have a single door, three louvres and four skylights in a 14 x 8 foot greenhouse.

Sod's law Gary..........!

you're not wrong there Chris

That'll recover.

Wow! Do you think so Phil? Good job I didn't chuck it!

My latest fan is a Honeywell very similar to yours Dave. Hopefully that and the glass removal will stop any overheating, now I just need to buy a few hundred tea-cosies to keep my plants snug on any chilly nights

purzo,

just get the fan close to the louvre vent as possible, it should help suck the air in from outside.

When I mentioned the 42°C, it was near to 35°C outside so still managing to keep to less than 10°C over the incoming temp.

If your greenhouse has the groove in the glazing bars where a capping bar would normally screw in, it is easy to screw in a small stainless screw and washer, the shade netting can then be hooked on.

A row of tomatoes can also provide some shade!

Thanks for the pictures Dave I see what you mean about placing the fan near the vent, that makes sense, I'll look into that but I've got plenty of clutter to shift first.

My greenhouse is made of wood so I don't have bar capping but I do already have external roller blinds shading the sunny side and have recently bought some extra green shading like yours to hang under the roof.
