Supplemental Lighting

Supplemental lighting is required to optimize plant growth, plant quality and ultimately profits in low light conditions such as mornings/evenings, winter days with low light levels, and cloudy days. Luckily, Ceres’ greenhouses are engineered with full-spectrum UV glazings, so that artificial lighting is always supplemental.

Understanding PPFD (Photosynthetic Photon Flux Density), DLI (Daily Light Integral), and PAR (Photosynthetic Active Radiation) are necessary in order to properly control the optimal amount, wavelength, and intensity of light for your plants during any stage of growth.

LED lighting

LED Grow Lights

  • Produces light by passing an electrical current through a semiconductor material
  • Up to 80% less energy than High-Pressure Sodium Grow lights (HPS)
  • Produces 90-130 Im/W, and converts 80-90% of that electricity used into PAR
  • Because of low heat loss, they can be placed closer to plants

HPS lighting

High-Pressure Sodium Grow Lights

  • Produces light in the orange-red spectrum (supports flowering and fruiting)
  • Relatively inexpensive compared to other lighting methods
  • Inefficient conversion rate (30% of electricity into usable light), the remaining is emitted as heat
