hi there
i found hydrogen peroxide in a few stuff ive read and decided to try it out. yes the regular stuff for cuts but make sure its 3%. i used a very small ratio - a few drops /litre.
my clones grew roots within days. seedlings also. as far as im concered hydrogen peroxide has an unstable oxygen molecule, and i found it beneficial for developing healthy root systems.
make sure not to use too much, i dont know what could happen... but a few drops diluted in water wont cause any harm, try it out.
