GH Hardwater Flora Micro 2.5 Gallon


•  Excessive Calcium is the main factor in your decision to use FloraMicro Hardwater. I f the total dissolved salts (TDS) in your water supply measure 200 ppm or more, we recommend that you obtain a water analysis to determine Calcium content. If the analysis reveals a Calcium content of more than 70 ppm (mg/liter) then you should use FloraMicro Hardwater instead of regular FloraMicro.

• FloraMicro Hardwater provides plants with proper nutrition when combined with the purified minerals in FloraGro and FloraBloom.

• Adjust the nutrient mix to meet specialized needs for each phase in a plant’s life cycle: seedling, vegetative, transitional, flowering and fruiting.

• Refer to the Basic Applications Table for mixing recommendations. Please measure accurately. Reduce nutrient strength if plants show signs of stress, or if growing in very bright, hot, or dry environments.

SHAKE WELL BEFORE MIXING. Always add FloraMicro Hardwater to fresh water first and sti r well, then add FloraGro and/or FloraBloom.Never combine FloraMicro with FloraGro or FloraBloom in undiluted form; doing so may cause nutrient lockout
