Silver thiosulfate feminizing is a method used to increase the probability of breeding female seeds. By spraying STS (Silver Thiosulfate Solution), a 50/50 mixture of sodium thiosulfate and silver nitrate, on a female plant, it will transform into a male plant. Have this plant pollinate other females and you’re almost sure to create female seeds.
