Re: Fw: Anthurium seedlings & fungicides

From: Denis denis at skg.com> on 2000.05.01 at 23:43:56(4495) I've never stopped to consider what percent of Hydrogen peroxide I actually end up with when I mix the zerotol material in water. I am using the medium rate as recommended by the Manufacturer, Biosafe Systems,[to be found at on the net], which is approximately 1.25 ounces of a 27% solution of Hydrogen dioxide (Zerotol) to 132 ounces(one gallon) of water. By my calculations it is approximately a 0.26 % solution, less than one tenth of a 3% solution. Maybe my calculations are not correct. I would think that it is possible that 3% might be to strong and could posssibly kill the plants as well as disinfecting the rooting media.
