How do I use PRO-MIX® HP®?

To use PRO-MIX® HP®, open the package, remove some PRO-MIX® product and place into a large tub or container. Lightly break up any clumps so that the PRO-MIX® is light and airy. Most growers prefer to add a small amount of water prior to filling containers. If you add water, add enough so that the PRO-MIX® product is slightly moist to the touch. Do not saturate. Fill flats, containers and/or pots, without compacting the PRO-MIX® in the container. Plant your seedlings, young plants, etc., then water in containers.

Not for chewers
Size: 8 Inch, Color: Yellow, Size: 8 Inch, Color: Yellow
My dog managed to pop this and completely chew through it in a matter of 4 days. It was definitely cute and she loved the size of it but with her chewing all the way to the core we have to get rid of it. I thought it was a good material but I guess I was wrong. Kind of sad considering the money spent only lasted 4 days

Great dog toy
Size: 8 Inch, Color: Pink
The amount of stupid and cute these dogs look like when they shake this ball and smack their own faces! It took a hot second for either dog to understand where to bite on the ball, but now that they do, they both will play with it for a while. Great purchase, came with a pump to blow the ball up.

Wonderful
Size: 9 Inch, Color: Red
Just bought my second one for my German shepherd. 1st one I bought a year ago. She managed to pop it within a few days. She still was able to play with it by grabbing ahold of the straps. Takes it everywhere. We call it her tether ball. Should've seen her when we got the new one out of the box. Hasn't left it alone since.
