Holland Secret will work in any situation, with any grow media and on any system. Holland Secret is a complete 3-Part fertiliser manufactured in British Columbia, Canada. It is micro-filtered to ensure sediment removal, giving a clean formula that will not cause salt build up or precipitation (nutrient fall out). Holland Secret is fully ph stable and helps bring your feedwater within a reasonable ph range meaning minimum adjustment is needed. Three-Part Nutrient Formulas are ideal for novice or expert growers as they are very effective and simple to use. They are suitable for all stages of plant growth from seedlings and cuttings right the way through to harvest time.
