Far-red light conversion of inactive phytochrome

"A process to trigger and speed the flower cycle of any short-day plant"



Red Bud Lighting

has a patented process

(United States Patent No. US 11,576,247 B2)

for “tricking” the plants into accelerating their phytochrome system which will speed the flower cycle of any short day plant. Our invention uses widely accepted plant science to induce flowering by manipulating the conversion rate of the inactive (Pfr) to the active (Pr) by exposure of the plants to a flash of far-red light.



Traditional growing methods utilize Mother Nature's natural process for moving “short day plants” from vegetative into their flowering and growth cycle.

“Short-Day plants have developed a biochemical mechanism regulated by the Phytochrome compound that changes form based on the number of hours of darkness or light but even more specifically based on the wavelengths of light the plant is exposed to.”

  • Outdoors, this natural process typically begins at sunset when the ambient solar day length reaches 12 hours and the plants require 12 hours of darkness to allow for adequate conversion of (Pfr) to (Pr).

  • Indoors, conventional culture deploys either light deprivation systems or a simple turning off of the lights after 12 hours to simulate sunset and begin the conversion process. However, this does not expose the plant to the necessary Far-Red wavelengths.



Red Bud Lighting’s patented process addresses other key industry concerns:

Harvest Staging
Control harvest timing to deploy labor and resources more effectively.

Climate Concerns
Increase biomass yields to reduce necessary acreage, irrigation and fertilization requirements.

Tropical Varieties
Our process allows tropical cannabis sativa varieties to finish in otherwise unthinkable northern latitudes.



In 2022, Wiseacre Farm, Inc. grew a 5000 Square Foot plot and used the Red Bud Lighting process on the entire crop. The results were the best Cannabis year this farm has ever seen, growing 810 lbs. or 367.5 KG of wet biomass in a 5000 sq ft field in NW MA. (73.5 grams per square foot)

A group of 10 control plants were subjected to either far-red light (5) or no far-red light exposure (5). The control plants with far-red light yielded 15275 grams, while the control plants with no exposure yielded 13,680 grams.

This was a true 11.65% biomass increase!
