I was doing some other research and came across this from ChatGPT:
Another study has introduced a novel method for stimulating male flower production on female hemp plants using a commercially available floriculture product known as Chrysal ALESCO®, which contains silver nitrate, similar to the active ingredient in STS but with improved shelf stability. This study compared the traditional STS method to Chrysal ALESCO® in terms of male flower induction and pollen quality. Both treatments were applied to female hemp plants, and no significant difference was found in the number of male flowers produced. Interestingly, pollen from Chrysal ALESCO®-treated plants showed a significantly higher viability rate compared to pollen from traditional STS-treated plants when assessed with fluorescein diacetate staining. This suggests that Chrysal ALESCO® not only matches the efficacy of STS in male flower production but may also enhance pollen quality, offering a viable alternative with the advantages of better shelf stability and ease of application.
Looks like that… 
maybe 7 oz bottle is ~$136 
Unsure on dosage rate too
ah, here we go:
Each ethylene inhibitor treatment was prepared for a final 1.48 μM silver concentration using a modified protocol from [20]. The total solution volume was 4 L of STS prepared by mixing 0.5 g of silver nitrate and 2.5 g of silver thiosulfate into 1 L of water and thoroughly mixing by adding 3 L of water to make the final 4 L solution. Mixing is required, and the solution must be made freshly for each application to prevent precipitates from forming before treatment.
A total of 4 L of ALESCO® solution was prepared by mixing 17.65 mL of the product with water to a final volume of 4 L.
Treatments were applied using a 1.5-L backpack sprayer (Uline H-7986 Backpack Pressure Sprayer; Pleasant Prairie, WI, USA), and individual plants were sprayed until runoff, or approximately 400 mL per plant [20].
Spraying was conducted by utilizing a modified protocol of three 1.48 μM silver concentration spray applications with a 5-day interval between each application once flowers were initiated [20].
The first treatment of STS and ALESCO® was conducted on 3 December 2021, when flower initials had formed.
The remaining two applications occurred on 7 and 12 December 2021 [20].
Male flowers were counted after plants had reached floral maturity but before the dehiscing stage of flower development on 7 January 2022 (Figure 4). The effects of the two ethylene inhibitor treatments were compared by a 2-way ANOVA.
