Interesting new product, vaporware still actually. Would make QWET easier and much more affordable. https://theherbalcompanion.com/

With pure coco as medium, smart pots can be set in saucers and bottom fed. Sitting in stagnant solution all day. Do not allow them to dry out, always some solution in the saucer. Get DWC grow speeds without the expensive complicated systems. Could not be easier. Maybe take your EC down a...

It is not my design, imaginary or real. It was the design posted in the OP. My original point, that got so very confused, was simply that a vertical HPS installation is far more efficient than the horizontal and that the COBs were in for a tough comparison. I already agreed with most of what...

Fine, can't compete may be overstating it. But, as I said upthread, I believe that in a horizontal growing style, a properly designed COB system can replace HID at 65-75% of watts input. I doubt you will be able to replace the performance of the HID with less than 90% of the power input and...

Thank you. I feel like I am in the twilight zone there. Just bad design and finger in the ears levels of ignorance and immaturity.

Just so we are straight. You start a thread called "High power cob vs hps vertical shootout." I try to explain that the output pattern of each leads to a very difficult comparison for the cobs and they won't be able to compete. You go off on a rant giving me a math lesson about how you are...

COBs obviously kick ass. However, the right tool for the right job, always. For vert, COB is the wrong tool. The radiation pattern alone should make that obvious. For those that grow horizontal and have heat problems with HID, COBs are a no brainer, just as bare bulb HID is for vert. I...

WWS, you are correct. COBs just can't compete vertically. Said this two weeks ago up thread and got yelled at for all kinds of crap that I never said. COBs are just now passing HPS in a horizontal hood setup. The bare vertically hung HPS is far more efficient than horizontal mounting in a...

Not sure about the dry ice freezing, sounds interesting. But, the heating in the still will drive off all those terpenes you are trying to capture with the fresh frozen.

Saucer + fabric pot + coco + bottom feed = win

dont use vg go read a bit in the concentrates section you want peg and pg, vg will not stay mixed

Yea, was just thinking out loud about how to maximize a given volume. So the LEDs are having a hard time keeping up, huh? Gee who could have foreseen that..... "Vert is one area that I think the COBs make less sense." That is the first sentence of my first post in this thread. You know, the...

The CXB1512 is pushing 200 lm/w at 5w each. The CXB1304 is around 180 lm/w at 3w

It may not be what you read, but that is what I said. Anyway, I have been giving this some more thought, particularly the reduced distance from the light source part. Sure, you can reduce the radius of your ring and perhaps add more towers in the same room. But what if you took that to the...

Good point. If you could bring in the diameter of each ring, you may be able to get additional towers into the same space at similar power levels. Personally, I really like idea of custom placement of each chip. For a vert installation the pin fin design modular heat sinks will work at up...

Your setup is not. You are correct. Look, can we agree that bare bulb vert is more efficient than horizontal inside a hood for HPS? If we cannot agree on this then this will be my last post here. Now, most people are not doing vert, for good reasons or bad, not the point. Therefore most...

I NEVER said that vert isnt as worthy. I NEVER said that COBs are not amenable to vert. Show me where I said either of those things. Let me try again for you real slow ok? The title of this thread is "High power COB -vs- hps vertical shoot out" All I have said today is a vert hung HPS bulb is...

What doesn't work like this? So far you have laughed at me and offered nothing to refute my contention that a vertical bare hps bulb is more efficient than a horizontal hooded one?

So now you know why vertical makes sense; cob, hps, Never questioned "why vertical makes sense", I can do the basic math. My point was simply that one of the major advantages for horizontal users of LEDs is the 110 degree output plane. Your design, while perfectly valid and serviceable will...

Vert is one area that I think the COBs make less sense. Interested to see what happens here, but one of the major advantages of the COBs in a horizontal grow is all light is directed down, not 360 degrees around a bulb. This is anything but an advantage in a vert setup. Of course it will work...
