Superthrive, formulated in 1940, is a hydroponic supplement which supplies ready-made carbon-hydrogen-oxygen groups that plants would otherwise need to wait to make. It is a unique vitamins and plant hormones formula. Use it with your cutting concentrate to increase your success with cuttings and increase the survival rate of difficult transplants. Super concentrated. You use only a drop per gallon.  Great for clones, transplants, or stressed plants.
