“This stuff definitely works well. As I was about to spray for the second time I dropped and broke the bottle, but was able to save some of the spray. I say that to say, I was only able the spray the plant three times but still ended up with a lot of pollen.”

“Very happy with the results! Easy to use, works as described. just mix in 20ml of distilled water and a drop of soap, then spray on your plants every 4th day until the solution is gone (takes about 30 days). 10-14 days after that, pollen released, females seeded, and i’ve chopped/harvested the reversal to store pollen for a future project. Very happy with the results!”

“The STS Spray by Cannabinology did not disappoint. I followed the easy instructions and waited 10 days before putting the other plants into flower. Looks like perfect timing!! Thanks.”

“We have purchased this product several times and it is fantastic. This STS solution works exactly as advertised (even better imho). By day 20 we get full reversal on nearly every cultivar. Their customer service is amazing as well. I highly recommend CBGYCA STS spray.”
