Application Requires Parts A and B to be used in equal amounts. When preparing the nutrient container, fill it two-thirds with water. First add Aqua Flakes A; circulate well. Then add Aqua Flakes B; circulate well. Harmonize the pH-value of the nutrient with pH- Down or pH+ Up. Top up the container with water. Add any root, growth or flowering stimulators. Your nutrient mixture is ready to water. Advice: Water the hydroponic medium before planting and keep them well-moisturized until the slip has formed roots. Consequently, keep the flakes a little dryer so that the slips roots need to work to find nutrients and water preventing the plants from becoming lazy Notice: Do NOT add Aqua Flakes A&B at the same time, as this triggers a chemical reaction in the nutrient resulting in sediment, incomplete nourishment and clogged piping. Contrary to what you might have heard with other nutrients, never use an oxygen pump in the nutrient container or in the growth table. This may have serious consequences for the stability of the nutrients.
