KINGMAKER™ Hormone Reversal Spray
KINGMAKER™ Hormone Reversal Spray
The Gold Standard in Feminized Seed Production
For over a decade, we have quietly refined and perfected a proprietary hormone reversal system that has become the foundation of our breeding program. KINGMAKER™ is not another silver-based spray, STS solution, or off-the-shelf reversal product. It is the exclusive hormone reversal technology trusted by Copycat and used to create the elite feminized seed lines that growers around the world have come to recognize.
Designed for serious breeders and preservationists, KINGMAKER™ promotes healthy male flower development on selected female plants without relying on harsh silver compounds. The result is a cleaner, more natural reversal process that prioritizes plant health, pollen quality, and genetic preservation.
