I think the main point is that ambient temperature affects the surface temperature of objects as well as any directed heat/light source. A cat may enjoy the warmth of the HID bulb, up to a certain point. Above that point, the cat may become uncomfortable and move. This is somewhat analogous to...

Why would that be?

never heard of a walk-in closet?

I just wanted to respond to this statement. When you say LED, are you talking about the individual chips, or the fixture as a whole? Diodes have limitations just like any other light source, but what “best” LEDs are you referring to? Most grow lights on the market are using similar...

Sorry, I was referencing the nanometer coverage more than the color temp. Spectral distribution is obviously somewhat different between the two light sources with CMH having a higher proportion of red in the spectrum. Hortilux 1000W Blue Phillips Agro 315W 4200K

I’ve actually never been that impressed with HPS grown flower. It can yield really well and grow larger nugs, but I was growing the same strains for a few years before I made the switch to 3000k CREE CXA COBs, and my buds were more dense, trichome laden, and had much better aroma under the LEDs...

Honestly, the healthiest growth and happiest looking plants I’ve ever had indoors were under Hortilux Blue 1000W. They didn’t have as much output as HPS, but the plants always responded better to the Blue spectrum. It just would have needed to have like 25-30% more output and would have been the...

You’re very welcome grower. I’ve also caused photoinhibition a number of times, and had to do a whole lot of reading and sort my problems out the hard way. I just try to remember that everything about growing is super dynamic and interconnected, especially when trying to diagnose issues or come...

I believe that it’s the phosphorus coating on the inside of the glass that actually scatters the photons after it absorbs and re-emits them. Glass typically will reflect/refract light, but the photons don’t lose energy like they do after transmitting through a particle like phosphorus. That and...

In regards to blue/violet/uv, I’ve had a suspicion that the reason people see somewhat negative reactions with “high”amounts of these photons in artificial light sources, is because of the sharp light points of the beam angles. In nature, a decent amount of the received blue and UV rays are...

I'm not sure where or what this particular spectrum application it is used in, but it doesn’t have the traditional cyan/lime green dip that most of the standard chips use and covers the blue/green end of Chlorophyll absorption much more broadly. I think it would be super interesting to pair...

The destruction of leaf tissue you are describing is photooxidation, also described as photo damage or solarization. The light avoidance you are describing is physiological leaf roll, which is a heat/drought/high light response. Most leaves can reposition their chlorophyll pigments, sometimes...

I just wanted to clarify this for you. There could be so many different factors as to why you could have a phosphorus “deficiency”. This doesn’t necessarily mean that there is not enough of the mineral in the soil. Purpling is just a symptom of a cause. This is outside the scope is this thread...

@Delps8 theres a few takeaways I’d like to brush on from that video. When he mentioned that Spectral Quality is over emphasized (around the 25:00min mark), it was in the context of cost effective growing and yield. Meaning to get the most plant growth, spectrum is less important than total...

Plants grow under light more so than not. Many studies have shown that increasing DLI has a positive correlative influence to plant growth, when mitigating stress. I’m proposing a cloudless season, where irrigation replaces rain. Again this hypothetical is in a controlled growing environment...
