Showing 18 of 18 crops

  • Lettuce growing soil-free in a hydroponic net potLeafy

    Lettuce

    Challenge: Heat spikes EC and scorches leaf tips (tip burn) on hot afternoons.

    Strategy: Level-triggered pure-water top-up plus a midday EC setpoint dip keep the solution gentle.

    • Water & flow
    • Nutrients & pH

    Best suited to: Aeroponic Tower · Standard NFT · Desktop Kit

  • Baby Spinach growing soil-free in a hydroponic net potLeafy

    Baby Spinach

    Challenge: Bolts to seed once the root zone climbs past ~22 °C.

    Strategy: Reservoir chiller and DLI-capped lighting hold the canopy cool through summer.

    • Temperature
    • Light
  • Swiss Chard growing soil-free in a hydroponic net potLeafy

    Swiss Chard

    Challenge: Heavy feeder that pulls potassium faster than other elements, skewing the mix.

    Strategy: Separate A/B dosing with a weekly EC reset rebalances the reservoir.

    • Nutrients & pH
  • Basil growing soil-free in a hydroponic net potHerb

    Basil

    Challenge: Loves warmth, but trapped humidity invites downy mildew.

    Strategy: VPD-driven extraction fans and a night-time humidity cap keep leaves dry.

    • Humidity & airflow

    Best suited to: Aeroponic Tower · Standard NFT · Desktop Kit

  • Rocket / Arugula growing soil-free in a hydroponic net potLeafy

    Rocket / Arugula

    Challenge: Tiny, fast roots are easy to over- or under-water.

    Strategy: Short, frequent ebb-and-flow pulses tuned to the small root mass.

    • Water & flow
  • Kale growing soil-free in a hydroponic net potLeafy

    Kale

    Challenge: Big leaves attract aphids and demand a steady calcium supply.

    Strategy: Camera pest-spotting alerts plus calcium dosing on a growth-stage curve.

    • Growth camera
    • Nutrients & pH
  • Tomato growing soil-free in a hydroponic net potFruiting

    Tomato

    Challenge: Huge transpiration and blossom-end rot when calcium transport stalls.

    Strategy: High-frequency irrigation with a stage-ramped EC and a tight Ca:K ratio.

    • Water & flow
    • Nutrients & pH

    Best suited to: Ebb & Flow (Tidal)

  • Cucumber growing soil-free in a hydroponic net potFruiting

    Cucumber

    Challenge: Drinks so fast the reservoir can empty and strand the pump.

    Strategy: Dual level sensors trigger auto top-up and a hard dry-run lockout.

    • Water & flow

    Best suited to: Ebb & Flow (Tidal)

  • Chilli / Pepper growing soil-free in a hydroponic net potFruiting

    Chilli / Pepper

    Challenge: Wants a long, warm season; cool wet roots rot it.

    Strategy: Root-zone heating plus a dry-back schedule between irrigations.

    • Temperature
    • Water & flow

    Best suited to: Ebb & Flow (Tidal)

  • Strawberry growing soil-free in a hydroponic net potFruiting

    Strawberry

    Challenge: Iron lockout the moment pH drifts, and warm roots stop fruiting.

    Strategy: Tight pH-band dosing and a reservoir chiller hold the sweet spot.

    • Nutrients & pH
    • Temperature

    Best suited to: Aeroponic Tower

  • Coriander growing soil-free in a hydroponic net potHerb

    Coriander

    Challenge: Bolts in heat and sulks at any root disturbance.

    Strategy: Cool deep-water culture with a rock-steady level — no sudden top-ups.

    • Temperature
    • Water & flow
  • Pak Choi growing soil-free in a hydroponic net potLeafy

    Pak Choi

    Challenge: Inner-leaf tip burn when airflow is low and calcium cannot move.

    Strategy: Gentle canopy airflow plus calcium dosing prevent the burn.

    • Humidity & airflow
    • Nutrients & pH

    Best suited to: Standard NFT

  • Celery growing soil-free in a hydroponic net potLeafy

    Celery

    Challenge: A 16-week cycle risks “black heart” from calcium deficiency.

    Strategy: Continuous EC logging and steady calcium dosing across the long run.

    • Nutrients & pH
  • Spring Onion growing soil-free in a hydroponic net potLeafy

    Spring Onion

    Challenge: Shallow roots dry out and stress quickly.

    Strategy: Frequent short flood cycles keep the thin root zone constantly moist.

    • Water & flow
  • Microgreens growing soil-free in a hydroponic net potMicrogreen

    Microgreens

    Challenge: A 7-day cycle where high humidity breeds damping-off mould.

    Strategy: Humidity and airflow control with clean, UV-treated water stop the rot.

    • Humidity & airflow
    • Water & flow

    Best suited to: Desktop Kit

  • Watercress growing soil-free in a hydroponic net potLeafy

    Watercress

    Challenge: Needs constantly flowing, oxygen-rich water or it stalls.

    Strategy: Continuous-flow NFT with a dissolved-oxygen sensor and a flow watchdog.

    • Oxygen
    • Water & flow
  • Cabbage growing soil-free in a hydroponic net potLeafy

    Cabbage

    Challenge: A long heading cycle and a heavy, pest-prone feeder.

    Strategy: Scheduled EC ramps and camera scouting flag trouble early.

    • Nutrients & pH
    • Growth camera
  • Mint growing soil-free in a hydroponic net potHerb

    Mint

    Challenge: Aggressive roots clog channels and starve themselves of oxygen.

    Strategy: Higher aeration and routine flow-rate checks keep channels clear.

    • Oxygen
    • Water & flow
