If you're looking for an alternative to Bushmaster, try Bush Load by General Hydroponics. Bushmaster slows down and halts the vertical growth, creating more compact plants. At the same time the vertical growth ceases, the plant starts to become very bushy, producing lateral branching and eventually producing much more surface area for flowers to form, thus greatly increasing the yield. Works well in soil or hydro, indoors or out. Bushmaster is currently unavailable.
