hello,
i have been using h2o2 (1% of 10 vol [3%] -- for ex: 10 ccs of 3% h2o2
in 1 liter of water) for *terrestrials* (nonOrchids) which *seems* to
control certain problems related to roots etc) and i wonder whether
anyOne has used it successfully for orchids (for example to increase o2;
either cure or control rot etc)?
i have found this link
Hydrogen Peroxide and Horticulture

i'd be very interested and grateful for opinions...
thanks in advance!

hi,
i have now heard that 10 ccs is *apparently* too much?????
apparently it should be 3 ccs of 3% (or 10 ccs of 1%) -- total 1%) FWIW
thanks for all the replies!
sincerely
Tanya
