H202 and Organics

Hi,

I want to start using Rain water in my DWC grow as my tap water has an EC of 0.4

I cleaned the barrow and the gutters, But it is far from stirle. So i was thinking of using some H202 in the water. before I use it.

I am wonder how long do I have to leave it stand before I can add my organic products. Namly Cann Zym and Liquid Karma?

Thanks.

20 minutes, according to the directions on the bottle (35%). Says to add, let water sit 20 minutes, then add nutrients. Hygrozyme says on the bottle it's compatible with h2o2, I'd guess Cannazym is similar. My friend is doing the same thing, to help his plants recover from a pump failure, and the plants really picked up.

Wow, 20 minutes. I was gonna answer 2 days. I was just going by the time that H2O2 is supposedly effective, and you should add more to your res every 2 days.

Maybe the active enzymes are not bothered by H2O2, but other organisms are either killed or severely hindered in their activity, just like using some chemicals with organic nutes.

HTH

It says on the Canna Zym bottle not to use with H2o2.

So I need to wate untill the H2o2 is no longer effective. By the sound of it thats around 48 hours, but maybe I should leave it 50 hours to be safe.

I was also wondering if I should let my plants have the water before then, so that everything is killed off then 50 hours later I add Canna Zym and Liquid Karama?

My Base nutes are Canna Aquare and will work fine with the H2o2
