Use of fungicides, bactericides, soaps and compounds.

Agree.
It's best to correct the problem/s with your growing conditions. I know fans are generally recommended but I've never used one and don't have fungal issues.
Also take a look at cinnamon ( in a paste), hydrogen peroxide and rubbing alcohol as more 'friendly' solutions to everyone indoors. I occasionally use Neem oil as a general spray and that has anti-fungal properties.
I remember using physan20 once - that caused an explosion of fungal problems as it upset the fungal ecobalance. I had creepy yellow mushrooms/ toadstools suddenly pop up, amongst others and I had a couple of WTF moments.
