Summary of Lettuce Trials

All Plants were grown indoors using drip, eb-flow or nft irrigation.
XTI has attempted to limit as many variables as possible in our trials.  Light flux between control and test are matched as close as possible.  If Test or Control has extra nutrient added the same amount of nutrients are added to the other.  Due to the vast variability in the LED market we have chosen to use a 400 Watt T5 as a standard control.

  • Patented Paws Technology

  • Low Power

  • Precision Indoor Ag
