Has anyone here ever bought fem seeds from a respected seed bank and had a herm show up? I sure haven't.
Why WOULDN'T you use fems to breed with fems?
"Prepare a 0.1 M Sodium Thiosulfate (STS) stock solution by dissolving 1.58 g of
Sodium Thiosulfate (Product No.
S7026) into 100 ml of water. Prepare a 0.1 M Silver Nitrate stock solution by dissolving 1.7 g of
Silver Nitrate (Product No.
S7276) into 100 ml of water. Store the stock solutions in the dark until needed to prepare the STS.
In general, the STS is prepared with a molar ratio between silver and thiosulfate of 1:4, respectively. Nearly all of the silver present in the solution is in the form of
[Ag(S2O3)2]3-, the active complex for ethylene effect inhibition.
Prepare a 0.02 M STS by slowly pouring 20 ml of 0.1 M silver nitrate stock solution into 80 ml of 0.1 M sodium thiosulfate stock solution. The STS can be stored in the refrigerator for up to a month. However, preparation of the STS just prior to use is recommended."
