Well I had a go & this is the result,There appears to be 2 broad STS approaches used by rec. growers. Option 1. Full strength STS applied just once on night of flip to 12/12. Approx 2-5ml per plant, spray aimed only at nodes. Option 2. Diluted strength STS applied 2-3+ times "around" time of flip to 12/12. Approx 20-30 per plant sprayed all over, at each individual application. I've tried both approaches and found better results with Option 1. Plants displayed much faster onset of balls and pollen, and higher amount of visible pollen. There may be environmental factors at play, that I have no idea about. But I've experimented with 9 different strains using both approaches, and on every ocassion Option 1 worked best for me. I use the Sigma-Aldricht STS formula online. I believe it's different to both formulas posted above. Not saying the other formulas are wrong, just that the S-A formula worked best for me, combined with option 1. Happy to chat privately with anyone that wants to try STS reversals in Aus, as we need more of this shit. Have a go ya mugs.
Use sts instead of colloidal silver. Google sts, should be available on ebay
Yeah all the reading I’ve done suggests this is the easier method.
Thank dude $69 on ebay but they said to go through there website but it was still the same price lol ill wait till pay day
Depends how many seeds you want!

I saw some like that at the chemist today while picking up a scriptI personally prefer CS as I use it for other things and it is edible/safe, and can be made at home very easily. The only negative is it takes about 10-14 days - one spray per day directly on the buds. I stop spraying once a few male flowers appear. Once they start to open and drop pollen I then use my finger to collect and pollinate a couple of surrounding buds. They continue dropping pollen for a week or more.
I've only ever sprayed a couple of buds, and smoke the rest
You need minimum 40ppm - I recently had great success with this one on a Bruce Banner auto:
Medicines from Nature Ultimate Colloidal Silver 50ppm
The Ultimate Colloidal Silver by Medicines From Nature is a high strength – ultra-fine particle size bacteriostatic water treatment with a particle count of 50 parts per million and particle size ranging from 0.0001 microns to guarantee effective action. Made From 99.999%+ Pure Silver Silver...
It is a good brand, some others make false ppm claims or dilute and use additives.
Why do something simple and effective like spray STS just once. Instead of spray CS every single day for 14 consecutive days
I like wasting 14 days of my life, instead of the same outcome only taking about ten seconds 
. I'll just go hop on my horse and cart to drive down the street. 
For comparison, a similar size small plant with 1 single spray of STS can produce 3000+ seeds. A low fertile reversal with STS will still produce about 500 -1000seeds. About $50 -$70 of dry ingredients is enough for hundreds of thousands seeds.
Hmmmm.. ok
