Rapid LED sell premade rails to put the heat sinks in.If you dont wanna go that route and make it yourself you can buy angled aluminum from lowes or Home depot or anywhere that sells it.The whole purpose of the DIY cob builds is to fit the footprint you wanna cover.
When i set mine up i took the square footage of the area 4x5 (20) square feet.I used this selection tool to select the wattage per cob and what drivers i needed.
http://ledgardener.com/cob-led-driver-selection-tool/
The goal is more cobs at less wattage for alot of light overlap.cobs are 120 degree beams so the more you have at lower wattages the more efficient.I dont really see the need to air cool LEDs honestly.for a 16 square feet you could go with 3 rows of 4 and put 6 35 - 38 volt cobs on an HLG 320 and drive them at 1400mA.
The vero D is 38.7 V X 1.4 amps giving you right at 650.16 cobs for a 4x4.Thats right around 40 watts per square foot. which is perfect IMO.
If you wanted to spend less money on the build you could get 8 of the same cobs and drive them at 2100mA with the same 320H drivers and only have to use 8.Less money on cobs and heatsinks but less coverage and less efficient.
Its worth the money to get more cobs and drive them softer.The amps you drive them at determines how many watts they are pushing.I could hook up 2100mA drivers to the cobs i already have and put 2500 watts over the 4x10 if i wanted to just by switching the drivers.
thanks alot guys! looking forward to the build! will price it out a few ways!!

I 95% agree. The only difference I would use strips or QBs over cobs. But that is just preference. I have cobs too. That I built under my bed. 10 3590s on 144mm pin sinks. Haven't even used it.

Hey I got a question. I haven't been PHing my nutrients for the last week which is kinda messed up because I started using great white and I cut my nutrients down a lot to 800ppm. I've been seeing some leaf twist like an s shape. Kinda reminds me of a PH swing, but I was wondering if you guys think it could be like P deficiency? Or could it be from a huge RH swing? We just had a system move past us (hurricane hector) and it brought a whole lot of rain and so much humidity it was like walking through a cloud at times. Now it's hot and dryer and it happened fast. You think that could cause the twist? Or maybe one of the other two.

Edit: here's a pic or two.

Maybe I worry too much. It's just these two spots, but they are on seperate plants.

QBs are ok but it's hard to get them to cover a big footprint.even 3 boards put together still falls a foot short of both sides of a 4x5.
There really better for 2x2s and 4x4s,but finding heatsinks to work with them and give you the spacing to spread them out is a pain in the ass IMO.
I was dead set on boards but that was my biggest issue with using them for a flowering room.
There alot like a t5,the light is only as good as the perimeter of the board.
Par drops off of led fast on the outside of the light.

im thinking bout building my first cobb setup. what do you guys recomend, will be doing a 4x4 bloom room first... what do you use to build the mount n such?
What's your budget? 16 cobs with heatsinks is going to cost way more than 4 QBs. I understand what @Heisengrow is saying about the light distribution at the end, but you can spread the boards out a little more to cover that. That's what I did using HLG 550 sizing as a template. But strips like what @whytewidow built is going to be the best option for light distribution IMHO. Just my 2¢.

Maybe you should take your own advice. :dunce:

Talk is cheap.
I showed you mine, let's see what you're growing.

How's your brix? (Assuming you know what that means.)
You're a trip bro.

If I was wrong and shooting down good advice for my own poorly conceived advice, I would admit it. How you fail to recognize that maybe you made a mistake shooting down someone else's idea that has tried and true results for your own that are scientifically proven to be poorly timed. Alfalfa has plant growth hormones, auxins, that his plants are too late in the cycle to use. It encourages new vertical growth and is super available, not really something that someone reusing their soil needs in week 5. Same with kelp, which you were unaware of. Different hormones and auxins so it can be used a bit later.

You tried shooting down the use of psg this late not understanding it is a slow release nutrient. You can't look at the npk and make a decision based off of that. It's a pellitized super hard slow release nutrient. Soaking it for 48 hours and it is still in the pellet form, hard as a rock. I have extensive experience using this in my soils.

Unfortunately I don't take pictures of my garden anymore. My state is very draconian in regards to just about anything, not just mj. I grow to the federal mandatory minimum sentencing guidelines. I am unwilling to risk my freedom in a dick measuring contest over a disagreement about a matter I have clearly been the victor. You can't find a hole in anything I've said so it goes down to an epeen measuring contest. If you want to "win" a debate using a picture against someone that just defeated you using words I'd suggest moving on to the next one.

Same here situation here ^. Once you grow big the camera thing kind of gets lost. Hell sometimes I don't even have a phone...Used to never have one. Fuckin find me. Really hard to do now though ; \ If you don't know how to then you don't need to. He is definitely right as far as the science and auxins go in his post. I reiterated some things he had already said in an earlier post. Hope ya two quit feuding :P

So now we know that you don't grow.
Cool.

You must have missed the part about using the solubles from steeping and not the solids (worm bin).
And you never asked about ratios.

I gave my indoor plants tea with alfalfa and kelp last week (see previous pic) and they don't seem to mind.
That was week 5 for an 8 week strain.

Anyhoo...

Tell us again how PSG won't dissolve completely because it's "pelletized".
That one cracks me up. (:
Do you even understand the difference between soluble and insoluble organic nutes?

You told someone to use a "slow release" fertilizer that's high in N and low in K -- to finish his crop???
Yeah, that's some good advice.

We could take a vote and ask how many folks think hitting their plants with 12-11-2 late in flower is a good idea... :roll:

Never saw the original post but I definitely would not be using alfalfa period past 4 weeks of flower unless my plants were pretty N deficient. That would obviously go for all sources of N. Alf is just too hot and available. I leave it out completely now for soil mixes and rarely use teas anymore. People the past few years seem have popularized making organics as technical as hydro with all the extras and it really makes no noticeable difference if your base mix is done right. Sure foliar some aloe and ewc now and again but you don't need all the extra shit it should be in your soil. Won't hurt anything most of the time but seems like a waste of time after doing it my self for years.

I used to make teas weekly for my outdoor.the clean up was too much of a pita so I just switched over to top dressing with dry amendments.i checked out mammoth p online....$65 for 250ml??? Think I'll go back to teas for my indoor.arent they the same thing? I never understood how beneficial bacteria survives being bottled or how active they actually are.i'll take psycadeli's word on it tho,dude be killing it.
Fwiw,i just did a simple ewc tea with molasses and a pinch of crab shell(the paint straining bag was my most expensive item lol)i'll be topdressing the gunslinger with a little gypsum and water light with my tea.

Bro I don't know why you think I don't grow. It's funny that I've got to prove I'm not blowing hot air to you. The guy who doesn't have the foresight that his plants in way too small of a container should have been staked up a month or two ago. Too much weight up top, not enough down low + wind = breakage without stakes. Then you blamed it on the genetics. Get a grip bro.

I understand it all bro. Read plenty of materials on many a matter dude. I know what's up with psg as an amendment and a tea ingredient, it seems you are lacking the amendment knowledge.

You keep going after everything but what I present. If you can't reconcile your differences with me you're just going on ignore. It's a shame because it seems like if you weren't such an ass we could have some good discussions.

Check the ego bro. We all have some things we could learn from one another. Sometimes you learn more observing conversation than participating in it. I only participate if I am adding good information or method. If you're not going to approach discussions with an open mind and continue cultivating your knowledge base then it's a waste of my time communicating with you.

I have no real issue with you bro. I know you called me a troll but I'm seeing it the other way honestly. You've handled this very poorly, I tried being cordial with you and you just attacked me personally.

I used to post my 4.2kw garage show but it's bigger now and I'm not a young unattached male anymore. I work a real job and have a large hobby garden in the wrong state. I wish I could move everything tying me down to my locale and post pics of my grow without worrying about stuff. I'm here to help pass on what I've learned from others or my own endeavors not argue with people 5 posts after I've already reasonably ended a side discussion on amendments and tea ingredients.

Keep it real and you'll get it in return.

Athena biosis just sent me a shipping confirmation on my free sample even though my state isn't on their shipping list. So I guess it worked for me for now.
When you get it, if ya would let me know how it was shipped. I run megacrop. They send a big bag about 8 weeks it seems like along with their boosters n stuff. . I have 100s of pounds of it. The first few came wrapped in yellow paper type shit. And it ripped open and you could plainly see the giant weed leaf and tell what it was for. So I contacted them. And told them to make their packaging better. Now it comes in a big cardboard box. If it's not noticable and you get being from a state not listed. I may try it out.

For sure I'll let you know what it shows up in

Again, take your own advice about the ego.
Seriously. :roll:

But your insight about pot size and the use of stakes was gold. Pure genius!
I'm sure my yield will double, so I owe you one.

It feels like there's some psychological projection going on here.
A mental health professional might be able to help you out with that.

Psychological projection
Psychological projection is a theory in psychology in which humans defend themselves against their own unpleasant impulses by denying their existence while attributing them to others. For example, a person who is habitually rude may constantly accuse other people of being rude. It can take the form of blame shifting.

Got my bag of recharge today lol. It's good stuff based on what is in it, but do not follow those instructions...That shit does not need to be applied every watering. If your beneficial microbes are dying off between watering's you got some major problems...Every 2 weeks should be more than enough. Once a week if you just have to love your plants too much.
