Polytunnel too humid for tomatoes?

[Whatalottie]

We got a polytunnel at the end of the year and the condensation made it very damp indeed. The vents were all open.

Do you think it'll be OK for tomatoes? I just have this niggle...

Thanks, Lottie

Condensation isn't good, it will encourage moulds and fungus gnats

Absolutely ideal for tomatoes. That's what I grow mine in. If needs be. open doors but use environmesh or similar to keep bugs out

By the time you need to use it for your plants the condensation, will not be a problem. I only find it a problem near the end of the season.

I had a great crop in mine, cucs too, but the chillies didn't like it. They were better in the greenhouse.

All my crops did really well in my polytunnel, had the front double doors open all summer and vent always open at the back (you know the mesh at the top of the door even though you can't actually open that door as there is a bed in the way). Didn't get any condensation problems at all though.

I tend to keep doors/ventilation permanently open during main growing season, in fact they are open most of the year and I've found no real problems with condensation.
