Gel4plugs is a gel based propagating aid which is unique in that, unlike other rooting gels, it is placed directly into the center hole of the plug. Just one ml or less is sufficient to ensure rooting of softwood and some semi-hardwood cuttings. The gel contains indole butyric acid and other active ingredients to ensure effective rooting and healthy root growth. The product is patented. The gel forms a seal around the cut surface of the cutting, aiding uptake and helping prevent dehydration and infection.
