“This stuff works really well on cannabis plants. I have pollen flowers all over my bud. It worked perfectly, read the label and follow instructions and it's flawless.”

“I like the STS because it actually works, I recently found my old empty bottles of colloidal silver, I counted at least 10 bottles, never, never even once found any sign of male flowers not a one, this STS really works. It's really potentt stuff!!! For the money it's really worth it if you want true results you won't be let down!!!!”

“I ordered this awhile back to work on a breeding project unfortunately that plan fell through so this item sat under my kitchen sink for over a year forgotten.
Recently I came across it and decided to see how well it would perform after over a year of storage.
Using RO water and following the instructions I mixed it up, following the spray times also included in the instructions I began my experiment.
I'm happy to say that not only do I have a bunch of reversed pollen the plant has self seeded.
Definitely a product to use if you are interested in creating your own female plants.”

-Bill H.

“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.”

-Leo S.

“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!”

“First time using got lots of pollen. Follow the instructions and it will be worth it.”

“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.”
