Protected Cultivation & Nursery Calculators
Nutrient solutions for greenhouses and hydroponics, and planning for plug-tray nurseries.
Hydroponic & Fertigation EC/pH Calculator
Calculate grams of fertilizer salt for a target nutrient ppm, the acid needed to bring down pH, and the ppm equivalent of your target EC.
Nursery Seedling Tray Calculator
Determine the pro-trays, cells, seeds and cocopeat or perlite needed to raise seedlings for your field.
Precision for polyhouses, net houses and nurseries
In protected cultivation, small mistakes are magnified: a nutrient solution a little too strong burns roots, and a nursery short of seedlings leaves gaps across the whole field. These tools handle the arithmetic.
- Hydroponic & Fertigation EC/pH Calculator – grams of fertilizer salt for a target ppm, and acid to bring down pH.
- Nursery Seedling Tray Calculator – pro-trays, cells, seeds and substrate for your field.
Frequently asked questions
What EC should a hydroponic solution have?
Most leafy greens grow well around 1.2–2.0 mS/cm and fruiting crops such as tomato and capsicum around 2.0–3.5 mS/cm. Follow the recipe for your crop and stage.
