Sounds like we're on the same page, which is why I put it out there. Been wondering the same for years. Personally, I think it's of the "well, that's the way we've always done it" school of thought. Quite a few folks still insist on peroxide for wound care. Have a friend who's a wound care specialist whose lecture on NOT using H202 has been heard by me too many times to remember.

My grandma insisted on putting butter on a burn. Never argue with your grandma.

I think the origin was hydroponic growing. I saw higher concentrations of H2O2 at the hydroponic store, to be used diluted in the reservoir.

I use 3% first aid strength to clean off mold on the exterior of terra cotta pots.

I am not being argumentative. I am correcting you!

LoL Since when is science an opinion?

I don't see it having much use for orchids. I did find 3% to have some utility in preventing the fungal disease known as "damping off", which causes plants to rot right at the soil line when growing Mesembs, a family of succulents very prone to the disease. I simply watered normally with the peroxide. However I found that germinating them outdoors in full sun was even more effective, probably due to a combination of air movement and UV exposure.
