Apologies .... my calculation refers to a dessicant dehumidifier

How long is your piece of string?

Re: Using a dessicant dehumidifier in the greenhouse
I find many of the larger, soft leaved Echeveria are particularly prone to it. By that I also mean many of the hybrids with gigantea/gibbiflora in them and plants such as Compton's Carousel. Agavoides and colorata types seem much less prone.
I would say both my dehumidifiers are set to switch off when the desired humidity is reached so they are not on 24/7.

A brusque comment.

Re: Using a dessicant dehumidifier in the greenhouse
After a fortnight of damp November weather, foggy and glum nearly every day and heavy rain at times, I noticed signs of botritus or similar on a few dead flower heads. Damp was visible on the greenhouse floors where rain water was filtering through the mortar of the base blocks or under the aluminium frames. The plants haven't been watered for best part of two months and the compost is bone dry in most cases but there is condensation on the inside of the insulation. I've had the doors open when practical, but to no visible benefit.
These are exactly the conditions which I fear increase the risk of plant loss.
So, the dehumidifiers have been turned on for the first time this year. They are set at the minimum rating (i.e. lowest energy consumption) and I expect they will only be on for a few days and only when the doors are shut. After just a few hours I can already see the floors are drier and the condensation is less.
Yes, this is going to cost me a few pounds, but I think there is a real benefit from using dehumidifiers at times like these.
