I have not received my order of Humboldt County’s Own Magnum (Magnesium and Sulfur Boost. Order was placed Aug. 28 2021. Like you said 17 days ago. I received a partial shipment the deep Fusion bloom. But no Magnum. Hope it’s a weather delay only. Thank you.

Humboldt countys own

They have the best products out there. After using a different brand for years, I tried HCO after a friend told me about them. After 4 harvests my plants are healthier, bigger and tastier. Great product, the whole line of products is superior, in my opinion, to anything else ou there.

Love the product. Used it for many years. Dont like nasty chemicals in our gardens. Citric acid and yeast do a fantastic job at killing those nasty critters and work well against molds.
When an associate brought plants over, years back full of rust mites, this was only product I found that actually stated it kills those buggers.

Great stuff

Was here soon after I ordered
