Hey-o. We wrapped a webinar with a commercial cultivator last month. They're using Pro 650 High Voltage fixtures. There's some good info in recording.

Here are the webinar highlights:

• Dr. Hopper and Dr. Wheatley are seeing improved cannabinoid production profiles under LEDs.
• Silver State Relief has 3 lighting scenarios: all LED, all HPS and checkerboard LED and HPS.
• The aggregate yield for the facility is 1.5 lbs per fixture.
• Lighting electricity costs were reduced by 43% in the all-LED rooms.
• Cooling costs in the all-LED rooms were reduced by 58%.
• Cannabis strains respond differently to various spectrums.
• Experiments with adjustable spectrums are underway to optimize cloning, vegetative, flowering and mothering.

You can find the webinar on the LumiGrow website.

Thank you, this looks like really useful information. I'll start using the lumigrow in about 2 weeks.

These pointers might help you out. This a rough guideline for growing cannabis with LumiGrow Pro 650 fixtures in a sole-source lighting environment. Use it as a starting point and adapt your parameters to meet your objectives. As always, listen to your plants and adapt accordingly.

Lighting for Vegetative:

• Each fixture covers roughly a ~16 square feet per fixture for cannabis. The higher the fixture, the larger the footprint and the lower the intensity.
• The lights should be 30 to 36 inches above the plant canopy
• The run time for the lights is 16 to 18 hours per day
• The spectral quality is Blue at 100%, Red at 100%, and White at 100%

Notes:
  • With higher sativa varieties we have seen some damage from high light intensity. Dial back the knobs or raise the fixture.
  • During vegetative growth, you could experiment with reducing the Red by 50% to 75% to encourage greater nodal development. Nodes produce flower.
Lighting for Flowering:

• Keep the same fixture density and hang height.
• Light run times will be 10.5 to 12 hours maximum
• The spectral quality stays the same as vegetative

Notes:
  • During flowering, you can try decreasing the blue by 50% to encourage quicker flower development if you want to keep the plants compact.
  • When starting flowering use 100% reduction in Blue for the first two hours of lighting, the next 8 hours use all wavelengths at 100%, and the last two hours the same as the morning spectral quality. This may or may not increase and speed of flower production but might be worth exploring.
  • If the flowers are bleaching, the light intensity is too high. Dial back the knobs or raise the fixture.
Lighting for Cuttings:

• Using the Pro 650 place the cuttings approximately 3 feet below the light fixture.
• Blue at 30%, Red at 0%, and White at 0%
• Light run times should be for 16 hours
• This should be done until roots have been established

Note: The Pro 650 is overkill for cuttings. But if for some reason you're propagating under Pro 650's, start with these tips.​

Additional Thoughts About Adjusting Spectrum:
  • During finishing/flushing in the last two weeks of flowering, we believe that we could reduce the red by 50% to encourage more volatiles to be produced creating a better tasting and smelling product. Our study with basil flavor points in this direction. This is still hypothetical.
  • If you discover something interesting, please share.
