Hoffmans No-Damp If you have never used this stuff before, don't go overboard buying some for the first time. It takes an overnight soaking to get it wet, It takes about 1/2 hour per plant to rewater, not the easiest to tell when plants need more water AND I still had damp-off with this product. I'll repeat myself, the cheapest, easiest method of controlling Damp-off. Use 25% less water Let surface of pot remain dry for about 12 hours.between waterings 0$, 0 chemical storage space. For you chemical users, There is a liquid NO-DAMP by Plant Products Co.Ltd. Brampton Ont. Canada L6T 1G1 I got some from Vesey's Seeds 4 or 5 years ago, Vesey's no longer lists it in their catalog.
