Towards the end of the flowering/fruiting phase nutrient intake slows down, yet there are considerable nutrient reserves left in the plant sap. If these levels are not depleted before the fruit is harvested, the resulting crop will have a bitter, metallic taste. By using biOpOnic Flush to supply the correct ratio of enzymes, organic plant hormones and catalysts, you enable your plant to remove as much of the excess nutrient stored prior to harvest. The use of biOpOnic Flush can be considered as important as using a PK booster to enhance flower production, and therefore yield. Available in 1 litre, 5 litres, and 25 litres, formulated for soft water, hard water, area specific or custom formulations.
