SUPERthrive is a WARF testing lab certified non-toxic liquid concentrated growth enhancer product for plants, which has been available since 1940. It contains ".09% vitamin B1, .048% 1-Napthyl acetic acid".

The packaging says that it should be included in the normal fertilizing program to improve some 50 phases of horticulture.
The packaging does not claim to have any N-P-K (macro-nutrient fertilizer) or trace minerals.

The hormone 1-Naphthyl acetic acid (NAA) does not occur naturally. Under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), products containing NAA require registration with the Environmental Protection Agency (EPA) as pesticides. The sale of Superthrive is prohibited in Oklahoma, Minnesota, and Oregon as an unregistered pesticide.
