A simple, easy to use pre-measured dry kit. Supply your own containers, spray bottle and distilled water, follow the easy directions, have a little patience and you can reverse your favorite female for a steady supply of seeds. I had tried buying the chemicals from fleabay and had no results ( my fault, chemical fault, plant fault ?...don't know) but using this kit on one female Golden Ticket with another next to it gave me over 100 S1's, and 100 F1's to play with. Certainly a lot cheaper than ordering seed packs........ Website has a few ways to order it, dry kit, ready to use spray bottle and a wet kit........ silverthiosulfate.ca
EDIT: Still had some Part A and B left so mixed up another batch in sprayer and applied to a Double Grape mini DWC plant. Got male parts showing a lot sooner than the first try. So it seems the separate parts are viable in the fridge for a couple runs. Got enough for about a 1/4 sprayer left so will try again in the next run or two.
