Greens grow best with FULL SPECTRUM — meaning light that mimics SUNLIGHT.
FULL SPECTRUM light supports EVERY STAGE OF PLANT GROWTH
400 to 450 nanometer light spectrum is used to grow healthy lush green leaves on plants. The best light range for plants producing fruit or flowers is 620 to 680 nanometer light spectrum. A full spectrum light contains the 400 to 450 light spectrum as well as the 620 to 680 spectrum. For a basic home indoor garden purchase good quality (safety is important) full spectrum grow lights with good quality diodes.
What’s a diode?
There are various diodes with specialized purposes. Let’s review the basic types.
Rectifier Diodes - convert AC to DC
Zener Diodes - protect electrical system from overvoltage
Light Emitting Diodes - emits light when forward based current flows through the diode. Light Emitting Diodes are used in commercial - home use grow lights.
Can Plants Get To Much Light?
GROWTH STAGE DISTANCE INFO.
Germination 24-36 inches Lower light-lower dessication
Seedling 18-24 inches After root growth lights can be lower
Vegetation 12-18 inches More light required
Flowering 6-12 inches Needed for Fruiting & Fruiting
