anyone have a good spray for a Grey powder mould I am getting on a few plant that are over wintering inside (they are damp and air is still), it seems to appear a lot - powdery, grey, fluffy mould that when touched flies off as dust.
what is the best spray? ideally ok on veg too

I use 5-10 grams of bicarbonate of soda to 1litre of water (and you can add a little soft soap if you like). Spray every few days until no sign of recurrance.

Remove affected leaves too, improve air circulation.
thanks!
