    A classic bloom enhancer, Monster Bloom™ has gained a reputation for its ability to assist plants during the middle stages of flower development. The high concentration of phosphorous encourages blooming and plays a vital role in plant metabolism. The potassium in the formula improves bloom and fruit quality while impacting photosynthesis, assisting starch production within the plant. Monster Bloom is very concentrated and should be phased out prior to the last two weeks of flowering. This will ensure the plant has the opportunity to metabolize all the power locked within Monster Bloom. The result will be a flavourful and abundant crop. Monster Bloom is a supplement and should be used as part of a complete fertilizer program. Learn More
