I took some clones that ended up molding so sadly, they got tossed. The mom has recovered and I'm about to try again except with peat pucks instead of rock wool. I'm about to put my pucks in water for them to swell up. If I add some hydrogen peroxide to the water that the pucks are absorbing, to try and prevent mold(as well as taking other precautions like more air.) will it hurt the plant?
