Any one got contact info for kingbrite

I disagree. I don't think 100w blurple will get the same yield as a 100w hlg.Bull, photons are photons, spectrum only plays a role in plant morphology not quality or yield
Each set photorecptors I would think has a max absorption rate. I would assume the wider the spectrum the more photosynthesis. Especially when intensity is high. Like green is missing from blurple. It penetrates better than any spectrum and you will gain photosynthesis deeper. But it's also used less efficient than other spectrums by the plants... red and blue being the most efficient spectrum used by the plants.
There is 2 types of efficiency.
1. Wattage to photons for that spectrum. Red being most efficient I believe???
2. Plants efficiency to use those photons in that spectrum.
That's why full spectrum is better imo.
Can do all red light but you are then only utilizing the receptors that absorb red light and when they max out your SOL for increasing intensity without adding spectrums used by the other receptors.
Photosynthesis is a general and overall term. A plant can take in more photons overall if it's using all of the receptors instead of the ones only responsible for red or blue or green.
Some rely on others receptors being used like red spectrum combined with infrared. Blue with UV
Yeah ratios of spectrum are important just like nutrients... thisbis where we are at now. Companies are trying to find the ratios best suited. But that also has slight changes even from genetics.for our purpose we need a red heavy spectrum for best flowering. Too much blue gives less yield, less flower sites and branching and leafier looser flowers.

It's a really complicated topic as taking into account my pervious post and then the impact of spectrum on type of growth.
I will say hands down intensity does trump spectrum... until you start getting to the light saturation points of those spectrums then spectrum becomes greatly more important in order to see any improvement.
Where that starts and ends... still not known AFAIK.
The reds definitely pump the efficacy number up from a watt to photon standpoint.Companies tend to sell what is available and cheap. That’s why the budget lamps like spider farmer and viparspectra have so much blue in their spectrum compared to say hlg flowering lamp which has more red diodes. Red diodes cost more than blue.

A pure red would have a ridiculous umol/w efficacy
I've been using 100w hlgs for a while now. I have the rspec, the 3000k and the 4000k. I haven't done a controlled experiment to prove anything. The 4000k is the brightest at 17000 lumens. The 3000k is 16000 lumens and the rspec is a bit less. I'm 95% sure the 4000k will not make the same relative yield as either of the others.but we need 2:1 red:blue for best results. So a proper lamp should have more red and be more light per watt. But we are already paying over a grand for one light. Are we up to 2k if they really copy a de hps spectrum?
Go HPS for that price.I doubt I can find both for under 300, for a 4x4.
YeaJust email Kingbrite, don't go through Alibaba. It and Aliexpress are data mining fronts for the CCP.
Also, spectrum does matter. Here's more detail.
Already ordered 1000w mh and hps for my 4x4. . . .For my other room ill spend more :)Go HPS for that price.

Depending on strain the 4000k could be good for the first 2 weeks after flip. A strain that's already short might be too short.they're recommending 3500k for full cycle and 2700k (like hps) for flowering. The companies I respect say 4K is for veg only. From what I have seen and heard that sounds about right. Of course there are plenty of other variables.
I only know that a metal halide of the same watts as hps flowers less buds and way leafier. The hortilux blue is a “sunlight” spectrum. But without the red spike even a 315 cmh 3100k can about match it.
Ima gonna be honest... I feel 4k will give a better product and hurt you on the weight side... worth it? That I can't say... but definitely 2700-3100 will produce more weight imo.
