What ratio of h202 to water?
    #1025271 - 11/05/02 06:04 PM (21 years, 6 months ago)

Can someone give me some exact numbers for mixing h202 with water for perlite humidification? All the FAQ's seem to just say "a small amount" and some talk about 3% peroxide and others say 0.5% peroxide.. a small amount, that's very vague. To me a small amount might mean a few drops, to someone else it might mean half a cup.. Can someone give exact numbers? ie. 1L of water + this much h202 of strength x (0.5%, 2%, 3%, etc.) Thanks.

give it 1 part peroxide to every 10 parts water....it depends on what measuring system your using...ie... 1 cup proxide to 10 cups of water will be fine!

I would estimate a ratio of between 15:1 - 20:1 of 3% solution...this should be dilute enough not to damage cakes, but still help combat bacteria (and to a lesser degree competitor molds). Healthy mycelium, a HEPA filter, properly pasteurized moisturized and pH-balanced casings, and proper air exchange are probably more useful/important overall at combatting contams.

Yeah, thanks for the info. I'm probably going with 1:20 ratio of 3% h202 to water. Have you actually tried this? Since your post just says "estimate". :smile:
