Feminized Breeding

Our Scalable System
Riot Reversal Spray provides a simple, powerful, scalable, and affordable all in one solution for every environment.
At Home
The main method of action behind female plant reversal is ethylene blocking while allowing the gibberellin hormone to thrive. It's just a simple hormonal switch, and Riot Reversal Spray flips that switch like magic regardless of your experience or space restrictions.
For Professionals
Calling all licensed farms, indoor operations, and fellow breeders alike! Our system system is tested, verified, and--as a result--fully scalable to fit your needs. For example, this last season, we reversed 13,000+ plants in a client project without issue. Yep. You read that right!

A Word From Our Founder
Matthew Riot
"Today several companies offer sprays that allow you to do this yourself, however most are based on old and ancient methods that have long been surpassed - like Colloidal Silver and Gibberellic Acid.
However, that's not where the story ends. As science has progressed we've learned of additiona, better solutions for Female Reversal--we are constantly testing and refining Riot Reversal Spray to ensure we continue to provide the best possible formulation to get the job done.
In short, it's taken me over a decade to figure out what I have about reversals! Riot Reversal Spray is the final culmination of everything we've learned. That's why I am so excited to finally share my personal formula with the public--the results are nothing short of epic!"

Frequently Asked Questions
What is the Riot Reversal Spray?
Our spray is an STS Base plus additional, critical elements I add to help improve the uptake and reliability of the process. STS stands for Silver Nitrate / Sodium Thiosulfate mixture – we feel this is the most stable and easy way for anyone to start reversing any dioecious plant species that relies on ethylene blocking to reverse sex.
Why an STS Base?
STS has properties known to increase the production of a hormone called “gibberellin” while also blocking the release of ethylene in the plants system. Doing this ensures stoppage of all female reproductive organ-related production and fully activates the plant on staminate male production for focused pollen dispersal.
How does this system make seeds?
Our feminized seedmaking system is a 4-step process. Step 1 consists of applying Riot Reversal Spray to trigger sex reversal of your favorite female plant. Step 2 consists of collecting feminized pollen upon successful reversal. Step 3 consists of pollinating your favorite females with your feminized pollen. Step 4 consists of collecting your very own feminized seeds.
