Green planet uses
triacontanol extracted from bee waste for use in Massive, not alfalfa.
Triacontanol is technically a mild natural PGR, it allows the plant to utilize Co2 more efficiently. Gibberellin which is in Massive, is also a naturally occurring PGR.
Where PGRs got their bad rep from was the use of synthetic PGR's which are largely banned for use in agriculture these days. Stuff like Paclobutrazol, Chlormequat chloride, Daminozide, and Uniconazole. You wouldn't want to use those PGR's. But Gibberellin and
triacontanol... No big deal.
