Propagator condensation

[Yorky]

I made a semi-circular cover, similar in shape/structure to a polytunnel, for a heating mat.

In order to prevent fungal disease, the condensation generated should flow down the sides of the cover rather than on to the seed trays which seems to be the case.

The problem is that when the front cover is removed for watering / inspection, the condensation drips all over the seed trays. This appears to be unavoidable. Has anyone any suggestions on how to prevent this?

Got a picture? I usually find that gently tapping the propagator cover causes the condensation to run down the sides.

There are no vents as such in the plastic as it is not airtight. Does it need additional vents ? If so how could these be created?

Yorky once the seeds have hatched take the cover off the seedling will grow quite well with just bottom heat.

It doesn't look as if the condensation is actually dripping onto the seedlings, so you should be OK. However, as Paul says you can remove the cover once the seeds have germinated. Just cover them up again for the night.

You can't avoid condensation - there's water and heat there!
I don't see a problem.
