Hi there,

This year, after many years of threatening, I finally got a
greenhouse.

...The greenhouse is erected on a concrete plinth that
was previously used for an aviary. I felt (rightly or wrongly) that I
needed to do something to insulate the concrete because I though it
would be quite cold.

Psst. Carpet tiles.
harbour mould spores :0)

And bare concrete wouldn't?

A hard (ie, not earth) greenhouse floor should remain dry

Oh yeah, hands up those who floor stays dry? :-)


unless watering
the plants on benches or in the side beds splashes over.

1. never heard of 'damping down' - common practice to increase humidity
in hot weather.

2. the OP is going to have pots, presumably on the floor, where do you
think the water will drain out onto?

As others have said it'.s a waste of time with all that glass around
