Grow-Cubes vs. Peat Independent Review

Miles from Hydrotech (one of the best hydroponics stores in Ontario, Canada) was asked to conduct a independent test for us. The purpose of this test was to compare GRODAN Grow-Cubes™ to a leading, peat-based potting mix. The results clearly demonstrate the significant benefits in using GRODAN stone wool over other potting mixes. The results of the experiment also indicate that mixing Grow-Cubes in with other peat/soil/coco mixes, even at just 25%, substantially improves overall growth rates.

Take a look at the video below (or watch a shorter version here), for a detailed breakdown of this experiment.
