Incredible Bulk

Bred to be a heavy weight performer,this plant does not disappoint. Ideally needs to be switched to flower before it is 2 feet tall,or else it will take over.Almost impossible to hurt this plant – it can take a huge range of ph / nutrient fluctuations, withstands extremes in heat and moisture, and joyfully devours any CO2 enhancement. This plant mutates and adapts to its environment – one perfectly grown, big plant can produce up to the same yield of twenty plants of normal size. Boxing-glove sized buds are to be expected on perfect large plants grown in Hydroponics, with CO2 enhancement.
