Grodan Stonewool (rockwool) is made from molten rock spun into cotton candy-like fibers and then compressed into cubes, blocks, or slabs. Where other rockwool brand manufacturers cut all sizes from one batch of wool, Grodan is unique by making different types of fibers. The purpose is to support the requirement of the plant in the different plant stages. Grodan has a tremendous capacity for absorbing nutrient solution while retaining plenty of oxygen for rapid plant growth. Grodan comes in graduated sizes. Seedlings started in cubes are easily transferred to blocks and then onto slabs, if desired. Seedlings or cuttings started in the Grodan cubes can also be transplanted into more traditional planters and growing mediums.

Grodan A-OK plugs are designed for seed and cutting propagation prior to "blocking on" into larger growing blocks. The V-shape design of the plug discourages tangling of roots between the plugs in the A-OK plug sheet. A-OK plugs come in a sheet that fits a standard 10x20 flat.

Athena Bloom is a simple and clean 2-part formula designed for the flowering stage of growth for fruit and flower-producing plants. We blend top of the line macronutrients and chelated micronutrients to achieve greater nutrient uptake ability across a wider pH range in any combination of grow method, water-type and media.

This 2-part blended liquid formula should be used in equal amounts during the flowering phase to stimulate the rapid onset of bud production, increase flowering sites, and promote high-quality yields.

Formulas are sediment free and are compatible with all dosing and irrigation systems  including fine dripper heads. Small amounts of micro-particles are occasionally visible in some conditions but will not affect mineral balance or system compatibility.

Athena Grow is a simple and clean formula designed for the vegetative stage of growth and for non-flowering plants. Our careful balanced mineral ratios help facilitate optimal plant development including photosynthesis, healthy respiration, and robust stalk and root growth.
