i don't remember the exact concentration, but i remember that i mixed 1 ml of 3% h2o2 solution with 19 ml of spring water in 20 ml syringe and let old seeds soak in that solution until they drown when i submerged them with a finger, normally after 12 hours. next step is i cracked them with my nails to make a breach in shell. this requires precision, so do it carefully. then proceed with paper towel.
pre-soaked in h2o2 kills bacteria, but soaking in diluted h2o2 makes oxygen transport inside to help a seed begin its life. i took it from some scientist article where they tested different concentrations on seed sprouting, so it's not my homebrew making)
love each other, don't compete with each other. separation is the illusion. the reality is that we are parts of the unity. stay open, spread love
