Head Masta nutrient additive is used during the flowering period in all types of hydroponic, soil and coco based systems. Achieving both high yields and high quality together can be difficult, as inferior products that increase yield, will often do so at the expense of quality. Head Masta is a sure fire way to get exceptional quality with improved flavours and aromatics from your high yielding crop. For an even heavier yield, use in conjunction with Mighty Bloom Enhancer.
