Grotek Monster Bloom has gained a reputation for its ability to assist plants during the middle stages of flowering development. The high amounts of phosphorous encourage flower development and assists with the plants metabolising process. The potassium further improves bloom development and quality while impacting photosynthesis. The potassium also assists with starch production within the plant, and helps with the ripening process. Grotek Monster Bloom should be used when fruit and flowers start to form, and throughout the beginning and middle of the flower cycle. It is recommended that you stop using Grotek Monster Bloom during your last two weeks of flowering. Always store in a cool dark place. Grotek Monster Bloom is suitable for soil, coco and hydroponic systems.
