Red Boom is one of Cannaboom’s signature flowering boosters, developed to push flower bulking, density and final quality during the most demanding stage of bloom. Its PK 21-21 formula delivers a powerful and balanced supply of phosphorus and potassium, helping plants develop bigger, heavier and more compact flowers while also supporting stronger aroma and flavor expression. Designed to work alongside a base bloom fertilizer, Red Boom is made for growers who want to maximize flower development and improve the overall finish of the crop without overcomplicating the feeding schedule. Suitable for soil, coco and hydroponic systems.
How to use: apply from the 3rd to the 6th week of flowering. Recommended dosage: 0.5-1 ml/L in soil and 0.2-0.5 ml/L in coco or hydro. pH adjustment is recommended.
