Just look for yourself
This stuff does exactly what it says it will. It really was a game changer for me. Never seen my plants so healthy and thriving through out the whole grow. Made stocks and stems super hard and strong and even made the leaves strong no BS and cheaper than most others I have bought.

Recommended to everyone I know growing
Make sure you shake this before using as it separates a lot, it really helps stiffen plants up so they can support your buds. I’ve never had problems with this burning plants so I use it very early on and it helps get that trunk thick early on. In the late stages you’ll get lots of knuckles too from using this. Don’t need much either
