A classic bloom enhancer, Grotek Monster Bloom (0-50-30) has gained a reputation for its ability to pack flowers onto your plants during the middle of the flowering cycle. The high concentration of phosphorus within the product encourages blooming and plays a vital role in plant metabolism. The potassium in the product helps to improve bloom/fruit quality and optimises photosynthesis and starch production within the plant. Stop using during the last two weeks of the flowering cycle.
