Dyna-Gro DYZYM032 Zyme, 1 Qt, 1 Quart, White

Used a lot of enzymes over the years this is right up with most expensive brands. I let my plants sit in water the entire time of their life span with no green algae. And for that worth it.

I have used Dyno-gro , three growing cycles, A great Product

Disintegrates brown root scum, leaving roots white and healthy looking again.

I honestly wasn't completely convinced that this was making a difference - that is until I ran out. The plants definitely showed a difference, not immediately but gradually over the next few weeks.After researching how the enzyme works and what it does I recently purchased more and the plants are gradually coming back. But not running enzymes of one sort or another isn't a mistake I intend to make again any time soon.That being said, the cost from all the enzyme companies for plant use is quite high and I've read posts from a number of folks that have tried pool and pond enzymes with some success. It's unclear if they are getting lucky or they are seeing placebo benefits; it would be tough to prove one way or the other without putting a lot of time into investigating it; but I suspect the time is coming when these plant enzyme marketers (most apparently don't produce their own enzymes) will have to come down to a more reasonable level or risk losing folks to other solutions such as the pool and pond enzymes.

Product was exactly what I needed! Havent used it yet, but it goes along side the other dyna-gro products I already have!

works as expected

I like that just adding with each nutrient change weekly keeps roots healthy and problem free. When added to nutrient mix at suggested rate doesn't change my ph. This was recomended to me by another gardener and I'd recomend to any other I have had zero issues since I introduced this product to my feedings.
