It can't be a lot though cause the triacontanol is what makes them expensive. The article I read said something like a hundred thousand euros per kilo or something [can't find citation]. ST is expensive, but not that much.
depends how they're sourcing it though. alfalfa's dirt cheap; for the amount we're looking for for our plants, it's easily conceivable that they're doing a plant-based extraction/concentration rather than using the pure form (which is almost always more expensive than the raw materials involved; the extraction process makes it that way).
