Root Booster (formerly G.O. Root Plus) organic root and growth booster TA Root Booster is a natural root growth supplement that helps plants establish healthy and vibrant root systems. It contains only natural vitamins, enzymes, organic and humic acids that stimulate root mass through completely safe means – not by using synthetic PGRs. TA Root booster is an outstanding additive for seedlings and cuttings, helping young plants develop strong and healthy root systems, and for mature plants it will reinforce and maintain health by improving nutrient uptake. You can also significantly increase germination success rates and improve the health of young seedlings by using Root Boostervv in solution to soak your seeds before planting. Use in conjunction with TA Fulvic for the ultimate growth phase boost combination.
