🏝️ 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.

Smells awesome

Bought this twice now. I use it when I use JLF or FPEs or anything that might have some "bad" microbes in it. Last a long time. I dig it

Good offers when you calculate time needed to make most. Love OHN!

Great option for anyone wanting to explore KNF or if in need/want of something not on deck this is perfect as well. Really actives soil microbiology and also works great as pest repellent. A little swig of OHN or in shake/smoothie is solid as well ;). Kiefr goat milk being base liquid with flax milk then all other goodies
