Master Kush RBX, a creation of Ethos Genetics, is a feminized photoperiod built on the robust foundation of 90s-era Dutch Master Kush. Backcrossed with Master Kush x OG Kush, this strain boasts the best attributes of its lineage - a strong OG backbone, earthy, piney, and spicy notes, and a chunky green flower structure. The quick 56-day flowering period along with a hefty yield potential of over 20% TAC make it a top pick among growers. Compact, muscular, and highly branching, Master Kush RBX produces spongy yet solid flowers without much need for training. A strong contender for growers wanting classic Kush flavor and high yields in a short time.
