Depending how the product is packed, transported, marketed, displayed and sold, the grower can normally expect somewhere about a quarter to, at most, a third of the retail price.
Unless Roto Gro can command a monopoly price through having a unique product ( possible, but it won't happen overnight and without big advertising bucks), I wouldn't have thought this equation would change much.
If their costs turn out to be less than other suppliers, then they'll be onto a winner, but that still has to demonstrated in practice
