    So as to unite and show our solidarity, we brethren of the discipline of growing vertically with LED lighting shall herein come together and share our successes, failures, leaps and foibles related to the noble cause.

    Or, someplace to post our shit when we get kicked out of the light bulb threads, lol

    I invited Yodaweed to the thread. You don't mind do you?

    I'll start; I want to address the assumption that a vertical grow must be round in shape.

    My own Super Silos were round, but only because of the nature of the HID light source. LED is generally much more directional, which renders the classic round or cylindrical shape unnecessary.

    Therefore, I believe the new shape of vertical growing with LED lighting is flat panels. One immediate advantage is that flattening the panel reduces leaf shading substantially.

    Cool! YOU babysit this time. I'm tired of wiping his ass.

    There was a guy on the old overgrow.com who grew vertical. Grew 4 big plants, lights were 1 1k in the center with 1 600 in each corner.
    My main concern with vertical leds is that they probably need more cooling since the heatsinks are beside the led instead of above. Have you observed this?

    I haven't personally observed it as yet because I don't currently have any LED panels with cooling fins.

    That said, vertically oriented cooling fins are more effective than other alternatives because they take advantage of convection currents; air next to the fins warms... and then rises, pulling heat away and bringing more air up from beneath. Short of active cooling, this is the most efficient way to orient them.

    To address the direction of heat flows from COB to sink, that's managed by conduction, which is why one uses thermal paste.

    thermal paste is supposed to be unnecessary with the qb boards, but may be a good idea for vertical. I'm thinking of a config like Rm3's except using the quantum boards instead of T5's.

    Convective cooling would work fine across the large surface area of a Quantum board. Again, the air picks up the heat and rises, carrying it away.

    Frankly, I'd expect the board to run cooler run vertically than flat.

    @robincnn would you care to do a bit of testing to see which orientation runs cooler? I think the results might surprise some people.

    here's what i'm thinking.... if you use my design and make tons of money then you owe me dinner lol.

    get ahold of a TIG welder and this could be a pretty cool contraption. someone make this come to life. im focusing my funds into my first two COB arrays. another cool idea would be to use round pipe heatsink with the fins on the inside and then mount the COBs onto aluminum pieces that are radius cut so they make good contact with the pipe.

    Folks seem stuck on round cylinders and forcing directing lighting to be something it isn't- namely, omnidirectional.

    Why not instead simply run LED lights onto flat trellis panels?

    I'm just thinking in order to maximize efficiency of a small tent. The square tube would aim light at all sides but I don't know if 4-6 cobs in a row aimed at one side would be enough.

    It all depends on the dimensions of the tent.

    This was grown in front of an over/under pair of 860W CDM Allstart lamps- but still on a flat trellis;

    I was thinking vertical quantum boards with joints in between boards so that the top boards could be over the plants when small and moved more vertical as the plant grows

    I think that's an example of disjointed thinking.

    DHydro,
    in the drawing you say 64 sqft that is 4x4 x 4 walls, wouldn't that be4x6 x 4 walls or 96 sqft.

    Yeah but I was was thinking that the amount of cobs that I suggested on that column I drew would only cover four feet up the tent wall. I don't normally run my trellis all the way up but I guess that would be the best way to maximize space and efficiency. To cover all the way up you would need a whole lot of watts in that 4x4 but it could be done

    About 1200W of good COB LED, or up to 2kW of HID would kick ass in there.

    If I'm already running 1k of Hps my guess is that 1200w of cob would be a whole lot cooler and easier to handle in the summer
