Well, I don't know what to say.
Here I am germinating hardy perennials one after another. Never washed a pot, not fussy about where the water comes from, no hygeine at all.
Never had a problem
But there's no heat, perhaps that makes a difference. and plenty of air circulation
I don't think you're growing tender exotics in a stuffy kitchen though are you nut? I don't bother washing pots most of the time either and I don't have a problem with botrytis either on the whole. I do see it on basil I buy from the supermarket during the winter but if you clean it up ASAP and open up the plant it's us usually the last you see of it. But the OP obviously has a problem with it, but if what you're grown needs heat and protection, all the conditions for botrytis then what are you going to do?
