Works well

It’s great to add with every other feed.

Great stuff

Great stuff, works the same as super si from what I've seen, And its half the price. It has helped thicken the stems and provides environmental stress protection, especially from heat. Make sure to use it in a foliar feed along with canna boost and rhizotonic.
