Roots Organics brings two potent liquid guano boosters, HP2 and HPK, each with its unique formulation and purpose to your garden. HP2 is a pure phosphorus supplement derived from liquid seabird guano, a nutrient-rich source. On the other hand, HPK combines the phosphorus potency of seabird guano with an added dose of potassium from langbeinite, providing a balanced nutrient boost.

Coco coir, a common ingredient in many high-quality potting soils, possesses a high cation exchange capacity, particularly for potassium. This characteristic means that plants grown in coco-heavy mediums can readily and rapidly absorb potassium. However, caution should be exercised to prevent overloading your plants with this element, as an excessive potassium concentration can interfere with the absorption of other essential nutrients.

To provide a solution for growers using coco-heavy mediums, we offer HPK as a separate option. This allows you to supplement phosphorus without unintentionally inundating your plants with extra potassium, thereby maintaining a balanced nutrient profile in your coco coir medium. This mindful approach ensures that your plants get precisely what they need when needed.

I am stunned
Color: Black, Size: Queen(20x30)
I had no idea what to expect from these. But for as cheap as they were I was willing to just write it off of they weren't that good. I had already picked up a new memory foam pillow to replace my previous memory foam pillow that didn't do well with dissipating heat. This new pillow was fine by itself, but when I put my pillowcase on it, the properties that made it cooling were negated. I'd get a bit of sweat on the side of my head or my neck where it was against the pillow all night. The pillow was supposed to be a cool one, but the pillowcase was not. So I grabbed this set. Smooth, no loose threads anywhere, stitching and seams are all spot on. And it's smooth to the touch. Got it on the pillow, and as soon as I laid my head down on it, I could tell immediately that this was going to be a different result that my other one. Not nearly as warm even after laying on it for a while. No heat buildup, no bits of moisture on the skin after being on it all night. This definitely works well, especially with my cool sleep pillow. Now I can have a far more comfortable nights sleep. For the price, it's a steal. I have no idea what longevity will be, but with two of them, I'm sure I'll get more than my money's worth.

Soft, not too thick and wash very well. Feels great against my skin and doesn’t make my hair frizzy. Color was perfect.

Cool, Comfortable, and Worth Every Penny!
Color: Light Gray, Size: Standard
I’m honestly impressed with these pillowcases! From the first night, I could feel the difference—they stay noticeably cool, which is perfect if you tend to sleep hot like I do. The fabric feels silky smooth against the skin without being slippery, and it’s really gentle on both my hair and face. I’ve also noticed I wake up less sweaty and more comfortable overall. They fit my pillows well and don’t slip off during the night, which is a big plus. After washing, they held up great—no fading, shrinking, or loss of softness. If you’re looking for pillowcases that actually help keep you cool and comfortable through the night, these are definitely worth it. I’ll be buying more!
