If you want to water a plant that has been whatered already you can. But it need to have atleast 100ml of hydrogen peroxyde to 1liter of the solution.. its a botanical garden trick.. im a diplomed botanist. Iy works 100%.. will prevent overwatering damage... I did rhis manytime to save plants that were been drown to save em. So if you want to change anything in a soil that is aleeady demp peroxyde is a big game changer. Most people don't know abouy it. I did 6h of reading for over 10 years. Many trick are still unknow. . They only timw i'l recomande notbusing it. Is in living soil without havingbtea brew and a boos of beneficial bacteria to replenished the soil afterward. Otherwuse fire at will
