Description
Hit your target EC every time — HydroCalc is a hydroponics calculator that works with ANY nutrient brand. Enter your reservoir size and target EC, and get exact ml measurements for every bottle in your nutrient line. No guesswork, no math, no wasted product.
Whether you grow with General Hydroponics, Masterblend, Fox Farm, Canna, Advanced Nutrients, Athena, Remo Nutrients, or your own custom mix — this hydroponic nutrient calculator has you covered.
✓ Hydroponic nutrient calculator for any brand — GH Flora, Masterblend 4-18-38, Fox Farm Trio, Canna Coco, Athena Blended, Remo Nutrients, Dutch Pro, and more. Add your own if it's not listed.
✓ Exact ml — no guesswork — Input your reservoir volume in litres or gallons, set your target EC, and HydroCalc returns precise millilitre dosages for every nutrient component.
✓ EC PPM calculator built in — Convert EC to PPM (500 or 700 scale) and back with a tap. Essential for hydroponics growers who track both units.
✓ Hydroponic feeding schedule presets — Growth-stage formulas built in for seedling, vegetative, early bloom, peak bloom, and flush.
✓ Masterblend calculator — Full support for the Masterblend 4-18-38 three-part formula. Enter target EC, get exact grams per litre or ml per reservoir.
✓ DWC nutrient calculator — Precision matters most in deep water culture where roots sit directly in the reservoir.
✓ Works offline · no subscription · no account — All calculations happen on-device. No internet required. No sign-up.
**Supported hydroponics systems:** - Deep Water Culture (DWC) - Nutrient Film Technique (NFT) - Coco coir - Flood & drain / ebb & flow - Top feed / drip systems
**Who uses HydroCalc:**
Hydroponics growers who are tired of mixing nutrients by feel. Indoor gardeners who want consistent results across every crop cycle. Urban farmers running small reservoirs or large commercial setups. Cannabis cultivators who need exact PPM and EC targets for each stage of the grow.
**Nutrient mixing calculator workflow:**
1. Select your nutrient brand or build a custom stack 2. Set your reservoir size (L or gal) 3. Set your target EC or choose a growth-stage preset 4. Get exact ml for every bottle — instantly 5. Mix with confidence, then log or share your recipe
**Why a hydroponics calculator that works for any brand matters:**
Every nutrient line has a different salt concentration, which means dosage rates differ significantly between brands. HydroCalc does the real calculation for your exact setup — not an approximation.
Running a 5L DWC bucket or a 500L flood table? HydroCalc scales to any reservoir size. The same formula accuracy applies whether you're mixing a small test batch or filling a commercial reservoir.
Download HydroCalc — the hydroponic nutrient calculator that works for any brand — and stop guessing your way through every feed.
