Are Cob lights ideal for veg and flower?

I'd suggest supplementing all COBs with far red and UV light if you want to get top notch buds.
Nah, no more diy. To obtain same wattage it would cost more and look ugly and no in line cooling. I don't have tools for diy and not so much electricity knowledge.

Bro in winter i veg and flower under a mix of 3500 and 4k cobs. The plants grow great and yield great.

I dont think the UVB is a necessity but i do use it. The hortilux bulb is a good compliment to the cobs in my experience. For more UVB i swap out the hortilux for the Agromax. My rig is a contraption. You def dont need either of those additions to kill it.

Do you understand what Relative Energy is?
HOW TO READ A SPECTRAL DISTRIBUTION CHART?
On the left of the chart is the percent of relative energy. The highest energy output of the light source is plotted as 100% Relative Energy. The 100% peak is used to compare the energy levels of all other wavelengths of light produced by that light source.
The bottom of the chart shows all of the wavelengths of visible light energy that the light source produces. For example, if a wavelength is at 50% relative energy, that peak has half the energy when compared to the 100% peak. Scaling each chart to 100% relative energy allows side by side comparison of light sources with different lumen ratings (intensity) or wattages. For example, a 1000W HPS lamp has more overall intensity than a 400W HPS lamp even though their spectral distribution charts are the same.



Not too sure what you chart was showing but it wasn't the relative energy of the light, it was some watts measurement which has NOTHING to do with relative energy, why do you think the chart of a 600w hps and 1000w hps look similar even though a 600w isn't as intense as a 1000w, Relative Energy has nothing to do with its wattage.

Benefits of UV Light for Indoor Plant Growth Ultra Violet (UV) light plays a significant role in all aspects of plant growth. Plants, in their natural environments, are exposed to natural sunlight which includes UVA and UVB light. Many of the lights used for indoor plant growth produce very small amounts of UV and some produce none at all. - See more at: http://www.eyehortilux.com/education-room/grow-guide.aspx#sthash.8zt6KbRi.dpuf



Think of what happens to your skin when you are exposed to sun for long periods of time. It begins to burn and sweat. Plants are no different. UV light activates a plant’s defense mechanisms. UV causes plants to produce oils, antioxidant vitamins and flavonoids to protect themselves from the damaging effects of UV. These compounds produce the vibrant colors, smells and tastes of your plants. If your light source does not produce UV, you are effectively changing the color, smell and taste of your crop. Keep in mind traditional lighting measurements such as Lumens, PAR and Kelvin temperature do not measure UV. Only a UV meter or a spectral distribution chart can provide information on a light source’s UV output. - See more at: http://www.eyehortilux.com/education-room/grow-guide.aspx#sthash.8zt6KbRi.dpuf

Try pretending that instead of the COB SPD being in measured in watts (which is irrelevant to spectrum), that the peak is 100% Relative Intensity.

What has changed??

Now can we compare the spectrums?

Couldn't agree more. Intensity has nothing to do with the spectrum being emitted. I think you may be starting to get it...

Bro I believe you 100%. I am a believer in cob's diy or not. My 200w bar (4xcxb3590) is amazing. But I can't have what I want with diy. I love the ideea of in line cooling, it will help me a lot. Gonna get a in line phresh filter and hook it up to the LED. And I want a dimmer on the pro9 so we are clear lol.

I have a huge phresh inline it is fantastic. I dont run it for cooling though.

Whats you plan for how to use the filter and the led inline?

Filter>Fan>Led>Outside
If needed I will add another fan and normal filter for more air exhaust.
Edit: I think it will help the led by not throwing dust and bugs inside where the cables are.

interested to see how you get all that into a continuous flow line. What type of case for the led & sinks?

In this configuration, you would not want an INLINE filter, but a regular close ended filter with a flange on just one end

I don't pretend on facts , they are either true or not ,you don't make shit up as you go because it makes you feel like you are right, the graphs you listed are using two different measurements and aren't comparable.

Indeed but right now I run an mobile AC and is exhausting the smell outside. I intend to push the air from the AC through the in line filter, with the help of a fan to not force the AC. After I will use it how I an really.

It's not diy. The new Amare Pro9IC is the Pro9 with a closed case and fans that push the air through one side of the pannel to the other, like the black dog. The fans can be unmounted and replace with more powerful one.

Ill have to take a look. I havent seen that. Ive got a huge fan and filter in a small room. No real issues with heat and it's been hotter than fuck here.

Inline filters are used to suck ambient air from a room in the middle of a ducting line. It's like putting a filter in the middle of your stretch of ducting. They're fucking stupid in my opinion. The way to get rid of odors, is to pull air directly through your filter from the very beginning, and keep that air in a closed duct until it's exhausted.
