Why is water quality critical for hydroponic growing?
In hydroponics, water is the growing medium – plants derive all nutrition from the reservoir solution. Source water problems: high TDS competes with nutrient formulas, chlorine kills beneficial microbes, hard water Ca/Mg blocks potassium uptake, and sodium stresses plants. Starting with RO water below 50 ppm TDS gives growers complete nutrient control.
What TDS level is ideal for hydroponic water?
Below 50 ppm TDS before nutrients are added. This ensures all dissolved minerals come from the nutrient formula. Target pH 5.5–6.5 vegetative, 6.0–7.0 fruiting. RO water starts near neutral and adjusts easily.
What water treatment systems does AMPAC USA recommend for hydroponics?
- 100–500 GPD – home growers, tent grows
- 1,000–5,000 GPD – commercial greenhouses, craft cannabis
- 10,000–50,000 GPD – indoor vertical farms, large cultivation facilities
All include sediment and carbon pre-filtration. Optional remineralization filters add Ca/Mg at precise ratios.
Does reverse osmosis improve nutrient uptake in hydroponics?
Yes. RO removes competing ions: hard water calcium blocks potassium uptake, sodium causes osmotic stress, chloride causes leaf edge burn. Using RO water allows growers to target precise CalMag ratios – producing more predictable, higher-yielding crops.
