Designed specifically for use in hydroponics, GrowTray-01OG double layer trays for creating systems with any of the hydroponic methods:
- intermittent flooding (Flood & Drain or Ebb & Flow),
- nutrient film technique (NFT)
Opaque black layer - made of high quality food-grade plastic to protect the interior volume from light, preventing algae growth.
White reflective layer on the outside - scatters the light from the phyto-lamps and thus improves the uniformity of lighting of plants and increases the the efficiency of the lighting unit!
