Stonewool Media Plugs, Cubes, and Slabs: All Sizes and Shapes for the Commercial Grower

Stonewool is a time tested material that is used in the commercial horticulture industry  by both hydroponic and traditional operations. Stonewool has its origins in a completely different industry- the construction industry. Stonewool used to originally be used for construction and insulation for structures. Then in the mid 1970’s scientists started to look at alternative methods of plant production using media that was different from soil based ones. Through testing, it was discovered that with slight modification, the stonewool material made the ideal growing media. From germinating seeds to cloning plants, and everything in between stonewool has the ideal conditions for happy, healthy plants. .

Stonewool Starter Plugs-

Starter plugs are usually defined as smaller chunks or pieces of stone wool that are perfect for starting or germinating seeds. A starter plug is usually a small piece of compacted moss, stonewool, coco coir, or other type of growing media. When a seed or sprout is ready to “block-up”, a grower can easily transplant the starter plug into a starter cube so the plant can keep growing. Red Rock Grow Block has a high-quality selection of stone wool starter plugs that are ideal for the commercial grower. Below is a list of the available starter plugs and what we love about them!

Mini Cubes, Starter Cubes, Rooting Cubes, and Clone Cubes-

Once again, the name of the stonewool product will depend on the stonewool grow media manufacturer. Stonewool mini cubes, stonewool starter cubes, rooting cubes, or clone cubes are typically used for larger seeds and smaller vegetative plants. Stonewool starter cubes are great for starting seeds, propagating cuttings, or cultivating clones, especially in ebb and flow hydroponic systems and drip irrigation systems. Stonewool mini cubes, starter cubes, jiffy cubes, or clone cubes can also, in most cases, seamlessly block up into a larger stonewool starter block or stonewool grow block.

Stonewool Starter Blocks are typically understood as a larger variation of stonewool media used for starting plants off properly.

Depending on the manufacturer, a stonewool starter block can also seamlessly “block up” or transplant into a larger size stonewool grow block. Crops can also be started in grow slabs and customized to fit into any area or new stonewool media further down the growth cycle.
