GT Optimum Grow is specifically formulated to meet the requirements of plants during their vegetative growth phase. This hydroponic solution is rich in nitrate-based nitrogen, which promotes fast leaf and shoot development, leading to optimal growth rates and enhanced flower and fruit potential during the later stages of plant development. GT Optimum Grow can be used with all hydroponic systems, including recirculating and run-to-waste configurations, and can be paired with various inert growing media such as rockwool, perlite, clay, and coco peat.
