General Hydroponics – How do I use Flora Series?
General Hydroponics Flora Series is the most commonly used hydroponic nutrient on the market. It can work extremely well if used properly. One of the beauties of the three-part solution is that you can adjust the ratios to suit your type of plant and stage of growth. General Hydroponics suggests the mixing ratios we’ve posted below. You will need to use an EC or TDS meter to know exactly how much nutrient to use – it depends on your desired nutrient level. Just be sure that you always mix the three nutrients in the correct ratio.
It is important to know that you should never mix the nutrients together. You should only add them one at a time into your watering solution/reservoir. Stir well between each addition to prevent nutrient lock-up.
