Learn the roots. Grow with understanding.
Explore every growing method, mix nutrients with clear units, and build a system you can understand, maintain and improve.
Growing methods ↗
DWC, NFT, ebb and flow, drip, passive systems and aeroponics—from equipment to harvest.
From reservoir to roots.
Follow a nutrient film system from its first inlet to its last root. Learn what each part does, what to inspect, and how the pieces work together.
12 min + model exploration →Growing methodsDeep water culture: build an aerated root bath
A complete single-vessel DWC workflow, from water level and air delivery to nutrient management and harvest.
6 min + guided practice →Growing methodsEbb and flow: flood, drain, observe
Build a flood table, size its working water inventory and tune irrigation from the medium’s actual wetting and drying.
6 min + guided practice →Growing methodsDrip and Dutch buckets: deliver to every plant
Design a serviceable bucket system for larger crops, then measure irrigation uniformity and drainage.
Interactive tool · 6 min + guided practice →Growing methodsKratky: manage the water and the air gap
Grow a short-cycle crop without circulation, with enough starting solution and a fixed support that preserves the developing air zone.
6 min + guided practice →Growing methodsWick systems: test capillary delivery
Build and evaluate a passive wick planter before asking it to support a mature crop.
6 min + guided practice →Growing methodsAeroponics: build for spray access and failure
Inspect a low-pressure spray chamber, verify root coverage and plan for the short buffer when delivery stops.
6 min + guided practice →Nutrients & mixing ↗
Elemental ppm, EC, fertilizer recipes, stock solutions and reservoir management.
Nutrient mixing: from grams to elemental ppm
Scale two documented fertilizer examples, read the bag analysis and calculate what actually enters the final solution.
Interactive tool · 6 min + guided practice →Nutrients & mixingEC, pH and the two “ppm” scales
Calibrate your instruments, record unambiguous units and interpret concentration without pretending EC is a nutrient analysis.
Interactive tool · 6 min + guided practice →Nutrients & mixingStock solutions and injectors
Calculate a dilution factor, keep incompatible salts apart and verify what the injector delivers.
6 min + guided practice →Nutrients & mixingReservoir management and solution replacement
Use a water-and-nutrient ledger to distinguish top-ups, rebalancing and a complete batch change.
Interactive tool · 6 min + guided practice →Media & propagation ↗
Match root support, moisture and drainage to the method; start and transplant healthy plants.
Choose media by water, air and service
Compare coir, mineral wool, expanded clay, perlite and propagation plugs in the system that will irrigate them.
6 min + guided practice →Media & propagationFrom seed to a working root system
Start consistent seedlings, establish root contact and transplant without importing avoidable problems.
6 min + guided practice →Crops & environment ↗
Leafy greens, herbs, fruiting crops, light, temperature and humidity.
Leafy greens and herbs: plan a repeatable crop
Choose a first crop, manage spacing and harvest timing, and avoid forcing every herb into lettuce conditions.
6 min + guided practice →Crops & environmentFruiting crops: support and stage-specific nutrition
Use a documented tomato ppm table to understand growth-stage changes, with irrigation, support and pollination in the plan.
6 min + guided practice →Crops & environmentLight, temperature and humidity
Measure the growing environment at the canopy and root zone, then adjust one limiting condition at a time.
Interactive tool · 6 min + guided practice →Source water ↗
Water analysis, alkalinity and treatment before the first nutrient batch.
Equipment & layout ↗
Pumps, measured flow, water inventory, drainage and structural access.
Pumps, head and delivered flow
Choose a pump from its operating curve and verify every branch under real installation conditions.
Interactive tool · 6 min + guided practice →Equipment & layoutVolume, drainage and physical layout
Account for every litre in circulation and every path it can take when the pump stops.
6 min + guided practice →Build, operate & troubleshoot ↗
Commissioning, observation, cleaning, fault finding and a complete operating budget.
Commissioning and daily care
Turn assembled equipment into a repeatable operating system, with a first-crop checklist and a useful log.
6 min + guided practice →Build, operate & troubleshootTroubleshooting and sanitation
Trace symptoms to measurable causes, contain a problem and clean the system without creating another one.
6 min + guided practice →Build, operate & troubleshootOperating costs and sensible scaling
Build a complete cost ledger, measure energy and labor, and expand from usable production evidence.
Interactive tool · 6 min + guided practice →Original teaching models and worked examples, with extension and manufacturer sources where applicable. Independent specialist review is pending. Numerical tools verify accounting equations; they do not certify a crop recipe or fish system.
