Janet, Thanks for your advice. I have sprayed the GH inside & out with
Biocide to kill off the fungus etc. I will rinse off after it has had time
to work then clean the glass. I've also decided to sterilise the soil with a
solution of Jeyes Fluid. The GH is 12' 4'' x 20' 4'' so that will keep me
busy for a few hours! Sandy
