Hi C-H's, If I may make a clarification to Dave Anderson's post: >First soak the seeds for one-half hour in a >10-percent (weight to volume) trisodium phosphate (TSP) solution. That is 10g dissolved in 100ml of water, or 1oz. dissolved in 10fl. oz. water. >.......Then soak >the seeds in a ten-percent bleach solution for five minutes, The bleach commonly sold in the US (and elsewhere as far as I can remember) is a 5% solution of sodium hypochlorite. It is possible to buy stronger solutions, for example 10% strength is used as a pool chemical. Do NOT put your seeds in such a solution. What is meant here is to dilute one part of the 5% store bought bleach with nine parts of water. [Quite the "Cardinal Chemist" huh? (But maybe I saved somebody's seeds.)] Regards, Cameron.
