That's the kind of advice I like hearing Churchy.One thing people with 730nm leds will agree on is that they cause crazy stretch if on during the day.
The results there have been fairly consistent.
I've also tested pulsing 730nm periodically throughout the night to see if it would inhibit flowering, and it actually did. It caused a crazy amount of stretch, and did not start flowering. From this, I concluded that while 730nm lowers Pfr/Ptot , it doesn't lower it all the way, but only to about 0.05. In order to get to 0, it needs darkness.
In other words, don't try anything funny. Just use the 730nm after lights out. Not before, not throughout the night, not on right before lights on, but only after lights out.
I wonder if there is any merit to his hypothesis and trial. Do infrared give off more heat than other spectrums? Your talking about heat correct?I read about one guy who was hitting his plants with IR 30 minutes before lights on to promote growth. He said it mimicked the warmth at dawn as the sun comes up.
I did not know this660 nm changes the phytochrome state and wakes a plant up.
Large passive heatsinks will glow for a long time in the infrared after lights out. Maybe that has a benefit as well?I thought about this too and a was a big proponent of passive cooling..............but was corrected by EH that even cheap modern computer fans have around .1% failure rate. The driver has a way higher chance of burning up.
the pros($$$) outweigh the cons with active cooling in builds imo
I'm under the impression that IR does not produce heat but that IR radiation does.Yes - IR is heat
I can't say that I know more about this subject than Newton but what I'm trying to say is is that Infrared, when discussing the wavelength spectrum, is merely a spectrum or description of a portion of the light spectrum, no different that UV(A,B,C). If there was something special about 600nm, it may have it's own name like OrangyRed but it's no more special than blue or green.IR is heat. When Newton was measuring the temperatures of the spectrum he was surprised when the thermometer past the visible red was hotter than the one with visible red light shining on it. When UV hits glass it is converted to IR. EMR = Electromagnetic Radiation. It is all radiation

No. IR light is IR radiation. They are the same thing. Read about some blackbody radiation. Also, photons are not heat, but when absorbed by a material, their energy is converted to heat.The strange thing is that while the sun and humans both carry IR radiation, which can be seen with tools, only the sun emits IR light. We obviously don't emit IR light like the sun does but yet we each possess IR radiation, or heat, when using and looking into specialized telescopes or goggles.

The experiment that Newton exercised sounds a lot like what William Herschel tried. And I'm going off Wiki as well.
As much as I know, Infrared Radiation, which is emitted by the sun, as well as human beings (and most, if not all living things such as plants), is the heat that were both agreeing on exists but you contest that IR is heat, where I'm proposing that IR is a light spectrum and that IR radiation is the source of heat.
I feel like were getting somewhere with this my friend
Ok so people and things, such as plants or the sun, emit IR radiation or otherwise heat correct? This is necessary for thermal imaging to function yes?No. IR light is IR radiation. They are the same thing. Read about some blackbody radiation. Also, photons are not heat, but when absorbed by a material, their energy is converted to heat.
