BudWise stocks two quite different products: a Plant Feminiser in 50mL and 200mL, and Heavyweight Potash — a potassium supplement for the flowering window — in 1L, 5L and 20L.
Potassium supports flower development late in the cycle, which is why products like Heavyweight are run in the second half of a grow rather than throughout. See additives and foliar sprays for the wider range.
