Easy to use; note that this is concentrated
This is used in greenhouses. It works exactly as indicated on the label. Note that this is concentrated, so if treating a small area, you will need the ability to measure out 10-30 ml to mix in a small sprayer.

Powerdery Mildew is a nightmare once you get it. ZeroTol is the answer.
This stuff is exactly what I needed. Got a nasty Powdery Mildew breakout this past summer in both my grow tents due to the humidity and my own laziness/ignorance. So I killed off a bunch of fully grow plants and sprayed whole tents down with bleach. And of course the PM came back in the next crop, so I killed more plants off. But this time I did some research online grow forums and with ChatGPT to find the answers. This stuff is safe to use directly on plants and will kill the PM. I found myself cleaning the shower mildew with it too. Works great!

Not environmentally or human and domestic animal safe
The Amazon page states that it's environmentally safe as well as safe around children or pets. However, upon receiving mine I read the instructions and it specifically states hazardous to humans and domestic animals, and also states that you need to protect the environment by not allowing it to run off into waterways. I purchased this specifically for use in my vegetable garden without any hazards, the safety of my pets and the lake that I live by. Very misleading, and disappointing!! Returning ASAP!!

It works!
If you follow directions, don’t mix too strong and know what you’re doing, like dimming the lights during foiler application, you will have success with this product. This really is a major tool in your gardening arsenal. This can help cure PM!

I wouldn’t recommend it for small in house hydroponics
The product works well, but it was hard to get everything right for use in my hydro systems. This product would be better suited to use in gardens or farms. It was worth a try for controlling the fungus gnats.

Heard great things about this product but feel like I have to research before I can use.
