🏝️ Outside Continental US

We ship to Alaska, Hawaii, Puerto Rico, Guam, Northern Mariana Islands and the U.S. Virgin Islands. Free shipping generally does not apply to large or bulky items shipped to these locations. Hawaii and Alaska do have more flexibility with this due to carrier policies. Quotes will be calculated at checkout or by request.

We do ship to Canada for select items. Canadian customers must choose “UPS Standard® Shipping to Canada with no Surprises!” at checkout to ensure proper customs clearance and avoid unexpected brokerage fees or delays. Orders using other methods may be subject to delays or rejection at customs.

Left residue all over my plants

I’ll probably never use this again I used as directed and it left this residue all over my plants and im not sure yet how that’s going to affect them. I do no recommend this.

BuildASoil

This is exactly what is supposed to happen! Wettable sulfur will leave a residue and it's a standard part of using this type of product. This coating of wettable sulfur is part of why it's so effective. Either way, it should be more clear and we will update our product page to clearly show this. Thanks for leaving the review so others can see, and we can get better and update our page.

Wettable Sulfur against WPM

I purchased this because I heard it would help fight the WPM I found coming back in my veg tent. I had success taming WPM in the past using citric acid but it always came back shortly after. It's now been over 3 weeks since I sprays the wettable sulfur and I haven't seen a single speck return. I've kept up with weekly sprays of the citric acid as a preventative. I'm so happy with how the product helped me combat WPM it will absolutely be my go to suggestion for friends in the future.

Wettable Sulfur

Great Item, easy to use just make sure to have a 2-4 week period in-between any oil based products and you will be ok. I've used this for dunking clones and as a veg IPM spray.
