Roots Organics HPK liquid bloom booster is a specially extracted natural source of phosphorus and potassium.

DERIVED FROM
100% Natural Seabird Guano, Bat Guano and Langbeinite

Roots Organics HPK liquid bloom booster features a combination of bat guano, an unparalleled source of available natural phosphorus, and langbeinite, a natural source of potassium that is carefully mined from ancient sea beds in the deserts of the American Southwest. Aurora Innovations has taken generations of gardening experience and distilled it into a distinctive, easy-to-use formula for the home and professional gardener. Roots Organics HPK is minimally processed to preserve all the benefits and amazing synergistic qualities found in our exceptional ingredients.

Bat guano, which is renowned as an unparalleled source of available natural phosphorus is combined with langbeinite which is a natural source of potassium, carefully mined from ancient sea beds in the desert of the American Southwest. Aurora Innovations has taken generations of gardening experience and distilled it into a distinctive, easy-to-use formula for the home and professional gardener.

HP2 and HPK: Two liquid guano boosters. HP2 is pure phosphorous from liquid bat guano. HPK is phosphorous from bat guano supplemented with potassium from a mineral called langbeinite. We separated these two products because coco, which is often present in good potting soils, has a high cation exchange rate with potassium, meaning the plant takes it up quickly. You don't want to overdo potassium in a coco heavy medium, hence the offering of pure HPK as a separate option.

Carefully collected from specific global sources, Roots Organics HPK is minimally processed to preserve all of the benefits and amazing synergistic qualities found in our exceptional ingredients.

Just right, great quality and value (in the price)
Size: 11.5 X-Wide, Color: Burgundy
Exactly what I'd expect from a Florsheim. I'm delighted. Folks, let me share one mistake I made on my way to a good fitting pair of shoes. I ordered some in my size (I have a big foot, especially in width). I ordered what I thought I needed and it came in wide enough, but too short (the short was the surprise), but we all are told: "Manufacturers vary in their sizes not only from each other but from shoe model to shoe model." I want you to know I believe in that when it applies to clothes, especially children's and womens fashions in my life's experiences, but NOT with shoes, especially main-brand-deluxe. I ordered the next half-size up and now I have too large, how can that be? I found out when I pulled the paper stuffing out, in particular the LAST glob that extends from the middle to the toe, that it WASN'T the last glob, there was indeed a rather small glob still way down in the toe, almost pointless for this minor bit of stuffing being separate from the other, but it was. I had already innocently troubled Amazon with returns of shoes that would have fit, so I'll keep the half-size too large as a life lesson. I ordered this pair in the size I believed I was all along and viola, a good fit. What changed? When that last toe piece of paper wadding that's hard to see and even harder with a big hand to reach, the shoe fit perfectly. That's a lot of trouble because of a small piece of paper that was hard to see, but that's why I write this review for you so that you can make sure all the paper is really out when you already think it is. Amazon has been good enough not to hold me accountable and in return I'll not only repeat buy, I tell you of my experience.

The Berkley Flex
Size: 7, Color: Cognac Multi
Very nice shoes, very comfortable, very nice leather. When ordering though, they fit a half size smaller than your size, because they are a tight-fitting shoe.

Better quality than most women’s shoes
Size: 7, Color: Black
I’m a woman and bought these for style and comfort after trying on too many others of multiple price points. These fit well and conformed to my feet after a single wear. Men’s clothes and shoes are so often of better quality.

Well made shoes.
Size: 11.5, Color: Black
Four stars because of the weight. Too heavy for my complete comfort. Also I have a narrow foot (C width) and these are too wide for me. Heavy socks make them wearable but not as comfortable as I would have liked.
