Holland Micro 1 Litre

Holland Micro is the core component of the Holland three-part feeding system. Use it with Holland Grow and Holland Bloom according to the current product label and feeding schedule. Add the measured amount to water, mix thoroughly, and apply to the growing medium or hydroponic reservoir as directed on the label. Do not use the catalog description as a mixing-rate guide; check the bottle label or manufacturer instructions for crop, growth-stage, dilution, pH, and EC guidance.
