Available in 2 distinct formulations, OPTIMUM supplies all the nutritional requirements for
healthy plant growth.
OPTIMUM Grow is formulated to supply the needs of the plant during the vegetative stage of its growth cycle. High levels of nitrate-nitrogen encourage rapid leaf and shoot growth, maximizing the young plant’s potential to produce fruit and flowers later in its life.
OPTIMUM Bloom is dedicated to the flowering and fruiting stage of plant growth. The bloom formulation contains reduced levels of nitrogen and enhanced levels of phosphorous and potassium, the elements required for the initiation and development of buds and flowers.
Optimum is suitable for all types of hydroponic cultivation. It is especially recommended for NFT, Flood and Drain and recirculation systems containing perlite or clay.
