When to open greenhouse door?

[ELsmandino]

Hi all.

I am using a plastic greenhouse to grow tomatoes and chillis.

Similar to this but a bit taller:

I am based in the south of the UK, so weather is not always brilliant but starting to warm up at the moment.

Until now, I always have the door of the greenhouse shut - I only open the door to water my plants at night. Is this a good idea?

I leave a tray of water at the bottom to make sure that there is some humidity.

The reason I ask is that I have just been reading about the importance of air-flow and greenhouses becoming too hot on sunny days.

Any advice on when to leave the door open (if at all) would be much appreciated.

Use Fans. I always scared to leave anything open because of Bugs.

You definitely need a Shade Cloth.

Dang it I was just thinking you really have no choice.

Here you would have a Shade Cloth, open the Door, if you can bring the plastic up about 3 foot on each side and maybe get some Fans.
