The reviewer finds it best for controlled breeding work where repeatability matters, because the proprietary aqueous STS solution is designed to block ethylene and reliably induce male flowers on female plants. It is not a consumption product and requires careful handling, but for saving phenotypes or creating specific crosses it delivers a clear, technical advantage.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProprietary STS formula:\u003c\/strong\u003e The kit provides a concentrated Silver Thiosulfate solution that blocks ethylene and forces female plants to produce pollen-bearing male flowers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete spray kit:\u003c\/strong\u003e Comes as an 8 oz \/ 240 ml STS base with a spray bottle so breeders can mix, apply, and repeat treatments without sourcing separate reagents.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEasy to use:\u003c\/strong\u003e Instructions recommend starting on day 1 of flower and repeating every five days to day 20-30, which simplifies scheduling during a breeding cycle.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEffective for feminized seeds:\u003c\/strong\u003e Pollen produced by treated females can pollinate untreated females to create seeds that are expected to be 100% female.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafe when handled properly:\u003c\/strong\u003e The formula is described as non-toxic and non-allergenic, but treated plants should not be consumed and handlers are advised to wear gloves and protective clothing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eValue for breeders:\u003c\/strong\u003e Contains enough STS to make roughly 8 oz of spray, suitable for many small or medium plants or one large plant for seed production.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis product is aimed at hobbyist and commercial breeders who want a replicable reversal method to save favorite phenotypes and produce feminized crosses.
