Quantums Overhead in Vertical Grow!

well even if they were ran in the same position the cobs were in they should work great right? i mean its been said these are cob killers right? i just dont see the point of mounting them high above a canopy that has been trained for vert growing.
In his layout if you mount the fixtures overhead in a vert room you now don't have to worry about the lights being in your way and also you can run more rows of plants in a smaller space. Really just no lights in the isles makes it incredibly easy to work on your plants. To me the biggest problem with vert growing has always been the lights hanging right in your way.

COB killers ? How can a COB kill a COB ? I haven't read anywhere that said the QB was going to make standard style COBs obsolete in growing.

so the plants are vert(tall and skinny) but the lighting would be better suited for a traditional growing style? it looks like suplimental lighting in this config to me.i guess im wondering what is the par or ppfd measurments of his fixtures @ 5 feet from the light ?

These optics are specially designed to put 100% of the light on the wall. That being said once he has his entire "rack" or basically 6X this setup in a row he will see the same PPFD levels as if he was hanging the lights vertically pointing at the plants. With this setup none of the light really hits the floor or ceiling. I know it seems odd but this is what they are designed to do.

From what I can tell it seems to be working as advertised.

It would be nice if I had a foot of headroom above the plants, but having two fixtures gives me the ability to tune things a bit for the low overhead clearance.

The two fixtures that @Stephenj37826 made for me have 4 quantum boards each, running at 80W apiece. The fixtures themselves pull either 330 or 340W, I'm not quite sure what accounts for the difference since in all respects they should be the same. It's not even a quibble, it just piques my idle curiously, lol

These two fixtures totaling 670W would be very serious competition for a DE fixture running at 1150W.

Proving this is my job and I'm looking forward to it!
shit talkin lights you have no exp with lol

...except they aren't. They do everything a COB does, only more efficiently and at many useful drive currents can operate without any more heat sink than an aluminum plate. The third strike is their light distribution footprint, and the new boards are the clear winner.
good ole shit talkin,before you even fire one up haha.
what i was getting at with my question about why you mounted these boards above the plants was,it looks like you are lighting up a walkway with nothing in it,and a skinny plant that is only about 8 inches deep.does that really sound efficient to you? if so why didnt you just mount your cobs in the same fashion ?
i also have a question about the lenses,how do you clean them,i think i read you say they dont seal against the led,so theres some amount of airgap?

So who's the one talking shit here? You have no experience wth quantum boards at all!

I won't engage with you anymore.

I think people are making there judgments based on pictures. In pictures the QB looks no more intense than solar sidwalk lighting. There has been a lot of cold hard test and facts based on these. Now that they are in the hands of growers we will see real world conditions. So much hate and thread jacking lol

The boards are working fine and they seem to be placing the light as advertised. They're running cool to the touch, not bad for being mounted an inch below the ceiling!

Now we wait to see what the plant has to say about them.

Mine are lush green to the bottom and praying hard to the QB god lol. I'm getting a lot more side lighting it seems also vs the blurple light. Much more easy to maintain atmosphere too. Mind you this is in my small grow space. It's nice to see them being used in different setups.

I see no reason why what I'm doing can't be scaled down.

Imagine fixtures like these mounted on the ceiling and lighting a shelf against the wall in your kitchen or living room, stacked full of plants like basil, chives, cilantro and even Christmas cactus.

It would take up very little space, use very little power and provides benefits we're all familiar with.

Not hating,i think his mounting approach is a good one for someone like me growing 5 x 5 x 5 plants. I just thought the board would be better used vertically in his situation since he spent alot of time training the plant to receive light from the sides not the top
Its pretty typical for him to evade my questions and deflect to something else.in this case he has oh about 2 days more exp than me with the boards but zero exp with de lamps run full cycle. Its very very hard to compete with gavita de i dont care who you are or if your grow sideways,up n down ect.
Tyy i wish you good luck on this test and look forward to pics of the buds down on the lower half of that plant.
