aright so i did a side by side with two different recipes...
Recipe #1:
First, a stock solution of 1.0L is made. It consists of two parts (A and B) that are initially mixed separately, each into 500ml of water, then blended together. Part A is ALWAYS mixed into part B while stirring rapidly. Use distilled water; tap water may cause precipitates to form.
Wear gloves while mixing and using these chemicals, and mix and use in a properly ventilated area. A mask will prevent the breathing of any dust, which is caustic. STS is colorless and odorless, and poses minimal health risks if used as described here. Note that silver nitrate and STS can cause brown stains upon drying, so spray over newspaper and avoid spilling.
Part A: 0.5 grams silver nitrate stirred into 500ml distilled water
Part B: 2.5 grams sodium thiosulfate (anhydrous) stirred into 500ml distilled water
The silver nitrate dissolves within 15 seconds. The sodium thiosulfate takes 30-45 seconds to dissolve.
The silver nitrate solution (part A, 500ml) is then mixed into the sodium thiosulfate solution (part B, 500ml) while stirring rapidly. The resulting blend is silver thiosulfate solution (STS, 1000ml).
This stock(STS, 1000ml) solution is then diluted at a ratio of 1:9 to make a working solution. For example, 100ml of stock STS is added to 900ml of distilled water. This is then sprayed on select female plants.
Results
I sprayed 4 weeks ago then again 3 weeks ago. Both times I sprayed for complete plant coverage like i was trying to kill mites, waited about an hour, then sprayed completely again. The second spraying was diluted 1:7 instead of 1:9
This plant never got the damaged look that the other recipe generated, it created less balls but bigger ones, and today I saw one fully opened, so I took it and moved it around on my hand, and sure enough, pollen! And a nice amount coming out too. I put some on the barely flowering blackberry kush and a few others, I put this plant up on a table with a fan behind it blowing toward the rest of the crop, so hopefully everything will get a nice amount of pollination going.
Recipe #2
Dissolve the 1.58g Sodium Thiosulfate in 100 mL water to create a 0.1M stock solution
Dissolve the 1.7g Silver Nitrate in 100 mL water to create a 0.1M stock solution. Store in the dark.
Prepare 0.02M (20mM) Silver Thiosulfate by adding 20 mL 0.1 M silver nitrate into 80 mL 0.1M sodium thiosulfate (or amounts in ration of 4 parts thiosulfate solution to 1 part silver nitrate solution). Store up to 30 days refrigerated (best to use fresh each time).
Results
I doubled this recipe so i would have enough to spray the whole plant, and sprayed 4 weeks ago then again three weeks ago. Both times I sprayed for complete plant coverage like i was trying to kill mites, waited about an hour, then sprayed completely again.This recipe seemed to make the plant look pretty upset, yellowing and mangled looking leaves. The clusters have more balls but are smaller so far, and grow in the buds more then the other plant which grew them more so under the bud sights ... No pollen yet, but I don't think they have ripened yet either. Will keep y'all updated.
Notes: This experiment is taking place in a greenhouse during the winter with less than optimal lighting. My guess is that results may happen a little faster if given full 12/12 of direct light. For all applications I would completely spray the plant, wait for 1-2 hours, then completely spray it again, covering them as if to kill mites.
EDIT: Incase anyone is wondering, here is the mix that PF had success with after our numerous failures....
1g Silver mixed into 60ml RO
6G Sodium mixed into 240ml RO
Mix the 300ml into 600ml RO for a total of 900ml..
Spray at night in cool place 2x. The 2nd application is done 2 weeks after the 1st..
I have ditched all plants that where messed up from other try's.. I got 2 fresh plants 1 Glue and 1 sdubb. I just put the 1st application on using his recipe. I did not have any plants larger than 12" so that's what I used. I'm told this will not matter both plants will get 1-3x larger anyway while flowering...
