Grotek MicroPower

Growing organically indoors can pose challenges not just from a lack of biology, but also from missing micronutrients. MicroPower provides a precise ratio of essential trace elements. This ratio is complemented by high levels of magnesium and Sulphur to boost critical plant functions. Added potassium assists with overall plant health and crop ripening.

Without true soil, no mineralization occurs. As such, growing crops in soilless media in greenhouses or indoor cultivation facilities guarantees that essential micronutrient inputs are required. MicroPower offers a balanced micronutrient solution for gardening in soilless media, thereby ensuring maximum growth throughout the crop lifecycle.

Magnesium is at the core of photosynthesis, enhancing the metabolism of carbohydrates and promoting the synthesis of organic compounds within the plant. Added Sulphur ensures peak production of essential oils, improving overall flavor and taste of harvested crops.

For soilless media or water culture, use MicroPower throughout the cropping cycle.  For soil based applications consult a soil analysis to determine need for supplemental micronutrient applications.

Growing indoors organically can pose problems, not just from a lack of biology, but also from missing micronutrients. As part of a fertilizer program, MicroPower is suitable for all plants.
