LED Spectrum Tuner for Space Crops

Space agriculture lives or dies on watts per photon: every joule of LED power aboard a spacecraft is rationed, so growers tune the exact mix of red, blue, green and far-red wavelengths to squeeze the most photosynthesis out of the least electricity. This simulator models a controlled-environment grow chamber the way NASA's Veggie and Advanced Plant Habitat do it — a McCree action-spectrum weighting turns your four LED channel intensities into an effective photosynthetic flux, a photoperiod slider sets the Daily Light Integral, and a 3D canopy of instanced plants grows taller and greener in real time as the underlying growth index responds to your spectrum choices.
