Do you prefer quantum boards or strips?

The problem many have in discussing this is personal. If you own a setup you often want to protect your ego.
Those who understand cob design understand light penetration, and those who understand strip design understand spread.
Now you can cover your canopy with strips, run close and its awesome. Enough penetration to run a SCROG or SOG easily.
Cover you canopy with boards...you now have more options. You can run them gently, like strips, or run them hard, like cobs for penetration. Or anything in between.
This doesnt make boards better. They can be more flexible if you have enough of them. Yes, they can be run at 3 or 4 feet and at 1 foot or even less although that is not common.
Knowing what you want is most important. Vertical space is required for boards unless you can afford a lot of them for your space.
Thus...boards are the more flexible option offering both choices depending upon what you want to do. But most people will pick one or the other.

also I will ad it depends on your situation. some people have to think about price, easy to pack so on and so on.

Thanks for all of your opinions. I'm still not sure if I'll buy strips but knowing me I will at some point.
Maybe Ill do one run with boards, one with 315 cmh and one with strips just to see the results of each light.

Have you ever grown with strips?
I had solid buds 2 feet down from a bridgelux strip build and it was only 320w
You can also run strips hard or more of them and soft, and you'll see the difference on the meter at about 2ft down.
I planned to chop these down and go from cut to get a better structure on them. But it was my first go with LED so I flipped them instead to see what they could do with plants which would have been too tall for HID. The top buds were right by the bars and would have been fried under a HPS in a hood.
The lowest buds in these pictures are a good 2 feet or more from the strips. They were rock hard.

Penetration, as a function of some special light source, is imho a myth. If you measure intensity a couple of leaves down in the cannopy you will get the same results from hps, cobs, strips or boards: not enough light to grow decent bud.
If you have buds far down in your cannopy its not from those buds getting light, their development is down to light absorbed by the top of the cannopy.
The root system of a plant cannot grow infinite bud, it will only go as far as it can. Plant management can make the buds larger or smaller, or decide where they grow.
Side lighting might of course change things a bit.

Yes.
As i mention in post 19, i have both strips and boards.
Boards and strips are the same thing. Boards can be used like strips. I do. But i also have the benefit of running boards much harder if I choose.
Thanks for helping me get there dude. I appreciate your help on the build man, big time. Same for everyone else who chipped in.

Finally i get a peep at your weird space, it was hard to grasp when you described it but now it makes perfect sense. Great harvest, seems like some nice genetics.

spot on, well said.
penetration you get in first from many lightsources hiting your target from many angles.
penetrating a leaf doesnt really work well, to a certain degree yes, but even with reflected and bounced greenlight or some far red you hardly get the inteinsity youll need for a nice bud.
it shouldnt be hard to imagine.
a light photon travels without losses, the loss comes when its absorbed, by a plant leaf f.e or its reflected by the tent wall f.e.

Before the LED revolution there were similar discussions of "penetration", although they were focused more around the idea of inverse square law and more intense HID lamps having better penetration, not so much about multiple light sources from many angles. I'm not saying that anyone's wrong, but it's worth noting that the goal posts seemingly have been moved.

What kind of light? Its doing a good job

Yes Chilled is top of line, my light is made by hydrotek, they only sell two types of led 440w and 600w but they do make good bulbs and have been around for years, so went with them, not that I didn't get a too good to be true deal.

From some company called Sundopt or some shit. Don't order from them. They fuck up orders left and right.

could it be that the better penetration mainly comes if you hang your HID higher and therefore have more refelctions over the tentwall, a more difuse light?
so maybe no one is wrong and is cooking the same water just in different pots.

It's certainly a possibility, but I never remember that argument being made prior to the influx of LED lighting; it was always the claim of inverse square law superiority.

inverse suqare law of course always applies.
but in the ned thats in direct realtion to the area to light always.
a quarter light means the other 3/4 go somehwere else, bigger area.
i just listened a podcast with bugbee (some linked me to it here), he was saying that in a HID the light goes to a big part over the reflector bouncing forth and back therefore giving more diffuse light and therefore penetration.

was the podcast
min 51.50 and especiially about min 55.
fixture with a wide beam spread have the better penetration, he say, diffuse light is the key.

Episode 73: Quality vs. Quantity: Common misconceptions about grow lighting with Bruce Bugbee
My guest this week needs very little introduction. If you’ve ever studied lighting you’ve probably read some of his research. Bruce Bugbee is a professor at Utah State University and President of Apogee Instruments. He is internationally known for his work with NASA to design food production...
