Got it to prevent pm then noticed I had thrips after first spray. So sprayed twice after that but not back to back and waited and still see thrips. It's hard to get every leave so I can't say that it's not working and I haven't done a lot of research on how to use this either besides mixing 3oz to a gallon in my pump sprayer and trying to shoot every leaf from the top and underneath, while in the dark.... While the plants are trellised . Wish there was like a smoke bomb that could kill pests and be ok for early flowering plants.

Worked as described. I had a mild spider mite infestation while in flower. I was able to save my crop and I honestly cannot tell anything was sprayed on the buds. Build A Soil also got this shipped out in fast order and for FREE. The Dr. Zymes website does not even offer that. So in the end it is also cheaper to buy it at Build A Soil. Thank You all.

Knocked back aphids in a week! Sprayed daily (more frequent than recommended)with lights on but dimmed(not recommended), and plants only had minimal leaf damage. So pleased with this product and will continue to use this. Thank you!

This product really works. Proper water PH and temperature are critical to getting optimum results. I use a heating pad on low under my Sun Joe 2 gallon portable sprayer to keep it in the sweet spot 65-80 degrees. This allows me to make several applications without runoff. This product is now part of my IPM. Dr Zymes saved my harvest.

I have bought this multiple times and I still like it as much as I did years ago. It helps a lot with pest issues. I use it every day when I have issues and it works well and kills the bugs. If you are having pest issues I would check Dr. Zymes out for sure.

Great for knocking down the live gnats. Can't speak to its effectiveness on a soak as I use neem for soil drench because it's also beneficial for the plants. Pay attention to the warning on the bottle about phytotoxicity - it's true!

I got it as a sample and tried as a foliar spray against spider mites. And it worked better than anything else I've tried. (And I've tried many) Just bummed I didn't have more to do a soil drench. That would have solved everything. But I bought more and it's on its way !!!!

This definitely works, but it isn't as concentrated as the Tweetmint. You need to use 4oz of Dr.Zymes and only 1 oz of Tweetmint per gallon. For 35 bucks you get 16 oz of Tweetmnt and 32 oz of Zymes. With that you can make 16 gallons of Tweetmint and 8 of Zymes. I didn't realize this when I decided to try it out. So in essence, you are paying twice as much for Dr.Zymes. I have used Tweetmint for years before this came out and have killed all kinds of insects, from aphids to spidermites it has not failed me. Plants are happy and healthy and I spray weekly. Plus it saved a buddie's grow from PM. I also use it in spray bottles to clean and sanitize the grow room and my house in general. Either way, these enzyme based products are much better than the toxins we used to have to spray!
