Possibly, but probably notWill a red digital display cause my blooming plants to hermie during dark cycle of bloom
...or use green displaysStrange that they don’t make these controllers with a snap down cover over the displays?
I have used a green headlamp at night in my flower house. No problems.Green light is photosynthetically active. According the Bugbee, green is no safer than any other color. His advice - if you must work during lights out, use as little light as possible and work quickly.
This is apromovideo that he does on "reagent grade darkness".
Good to hear.I have used a green headlamp at night in my flower house. No problems.
It is very well established that the flowering hormones, Pr and Pfr, respond specifically to wavelengths of red light ("red" and "far red"). Does Bugbee challenge this?Good to hear.
The color of the light does not matter and, listening to his presentation, I was surpised as to how much light it takes to cause an issue.

I've heard that for decades and it struck me as strange because I was taught in grammar school (high school in NA) that it was the green colored chlorophyll in the chloroplasts that caused us to perceive leaves as green. That was some time ago but, from what I can determine, it is still correct.could be it takes a more intense light if in that part of the spectrum. the leaves of plants are green as that is the wavelength they don't absorb. it looks green to us as that is what is reflected back.
So then, the color of the light (wavelength) does matter in terms of the flowering hormones. This is independent from whether or not the wavelengths are photosynthetically active.Not that I'm aware of.
I think you brought it up earlier that flowering initiation is a result of red and far red.I said, "It is very well established that the flowering hormones, Pr and Pfr, respond specifically to wavelengths of red light ("red" and "far red"). Does Bugbee challenge this?"

As far as I know, studies were done to establish the effects of the flowering hormones using just the "red" and "far red" wavelengths, without other wavelengths present. It turns out that a full spectrum bulb will accomplish the same thing, in terms of preventing flowering.
