Experiments

What we are testing.

Each experiment starts from one question and a stated hypothesis. Its status here is always the real one: in preparation, in progress or concluded. Protocols are published before results.

  1. Start date not setIn preparation
    Question
    In a closed-loop hydroponic system, how does the light spectrum affect plant growth relative to the water and electricity the system uses?
    Hypothesis
    The spectrum changes how much edible biomass is produced per litre of water and per kilowatt-hour, not only how much is produced in total.
    Treatments
    • LED spectra to be defined in the protocol
    Measures
    • Fresh and dry edible biomass at harvest
    • Water added to the closed loop
    • Electricity used by lighting and the system
    • Air temperature, relative humidity and CO₂
    • Nutrient solution pH and electrical conductivity
