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.

They look good and seem well built.
Color: Brown
These are very well made and look really good. They ended up being too small for my need, but that was my fault on measurements. I would highly recommend if you are looking for corner shelves.
