10,000 Watt 10 Plant 13 Gallon Rdwc [3d Model Incl. Inside Thread]

[CCCmints]

I think your cooling needs could be more than you think... in your previous design you were removing some of the heat with the fan loop but here 100% of the heat stays in the room. Also I think that build needs a LOT of tweaking.

Well, then what do you suggest? I've got some really experienced dudes on other forums helping me with the build and they aren't saying this needs "a LOT" of tweaking...What do you not like?

Go Vero if plan on pushing them 75-100w, not low. If want low efficiency look at Citi

Mostly wondering what's up with the lenses and why 15 per plant? Like the poster above said if you are going vero drive them harder and if you wanna run 15 for some crazy reason run citi or the luminus Cobs. So long as you pay no mind to the tards at grasscity you should be ok. I would do 9 per @2100ma for 75w per and skip those lenses but that's just me. Also 6' pieces of 3/4" angle are $6.xx at Lowe's I bought 2 yesterday.

Just curious, do you plan on making a grow journal for this? I'd be interested in following along

When I created the model and posted this thread across various forums, I had no intention of using LED (as you can see in the model). I simply had a curious thought and decided to drop a post about LED. This tiny bit of curiosity and small post on a forum turned into me taking the idea seriously. I've only ever grown with T5 lights and HPS lights. This was 6 days ago. I'm not one of those people who thinks having people help me get shit right means a blow to my pride. The fact of the matter is, I openly admit to knowing very, very little about LED to the point where some of my posts on it make very little sense to people who are well versed in this technology.



As for your questions, the whole per plant thing is not fixed at this time. Maybe 10, maybe 20, possibly 30. I don't know yet. I'm not even a week into planning and 4-5 months from building the op. Why 15 per plant? Because that really isn't an exorbitant amount and my understanding is that the harder you drive your COBs the less efficiency you receive and I'm willing to spend the money to have higher efficiency. Not to mention you get better coverage with 15 rather than 9...


I used this data to choose the reflector. https://www.rollitup.org/t/lens-and-reflector-optics-for-cob.893660/ Why are you so against that choice? Are you saying not to use any optics? I’m not doing that.

There will definitely be a grow journal on this.

I'm willing to spend 5k on LED lighting so long as it is equivalent if not greater to yield with a 1000w of HID. I've got a lot of time to research tough so hopefully I come to the correct choice in the end.

one thing to keep im mind is that switching from T5s and HPS to LEDS involves a learning curve. you should start on a small scale till you learn to grow with LEDs and see how they work in your environment with the strain you grow.

15 cobs doesnt even work out into even rows.... 9 or 16 would give you even rows. I guess i am not really understanding the whole optic thing but maybe you can explain your thought process.

I understand this. If I were the one funding this whole thing then I'd probably do an entire cycle with half the light and less plants, but that isn't the case unfortunately. I'm sure it will work out.

What do you mean it doesn't work out into even rows? This is what I've envisioned: http://i.imgur.com/glnFb4S.png

As for the optic thing, if you review the data I linked in my previous post, you will see higher PAR in tests where optics were used, regardless of the model tested, compared to running LEDs without optics.

 

[MonkeyPickAss]

What i mean is why are the spacings between the cobs not equal?

 

[CCCmints]

I don't understand what you mean by they're not equal...Why Would 9 or 16 COBs be equal but 15 can't? I went ahead and scaled it out to see what you mean and I still don't to be honest with you. The way it looks, maybe the COBs will be millimeters off in terms of equal placement at most, but I don't see that as being an issue.

For the perfect square fixture i believe. 3x3 or 4x4 instead of 3x5. Plants would get even lighting every sqft under the fixture

Yeah it's a 4x4 fixture. The COBs are definitely evenly placed at 15.

 

[MonkeyPickAss]

They can't be..... You have 3 rows of 5 lol how can that be evenly spaced? 4 rows of 4 or 3 rows of 3 would be evenly spaced but you can not evenly space 3 rows of 5.

Here's a high-end LED company with 3x4. http://timbergrowlights.com/900-watt-cree-cxb3590-square-framework/

Those lights are evenly spaced apart. Which part do you see that is not evenly spaced? The distance of the borders in all directions are equal. The distance between the COBs is equal. I don't see why you think things need to be 3x3 or 4x4 or 5x5...I've illustrated exactly what this fixture would look like and its fine. I linked you to high-end models doing something similar.

Here's another high-end light...2x3: http://www.pacificlightconcepts.com/product/plc-6/

Do you have specific reasoning for why you think there needs to be the same amount of rows? I honestly do not see what the problem is and neither do people who sell high quality LEDs.

If you can't figure out why you need 3x3 4x4 or 5x5 to be spaced equally I'm not sure what else I can do to help you. I mean seriously 3x5, 3 across somehow covers the same area as 5 do in the other direction? If you are covering an area that is 3'x5' then you could cover evenly but how the hell does a rectangle evenly cover a square? 9 5/8" in on direction and 16" apart in the other....

logic I suppose is the reason I want them evenly spaced. Saturating certain parts and leaving other parts wanting is just plain silly.

Yeah I understand what you're saying...Looks like I'm being a bit stupid, thanks for pointing out the obvious.

 

[MonkeyPickAss]

I think you got some killer ideas I just don't wanna see you spend more than you have to. I am of opinion that you should do 9 cobs running at 75ish watts each. Put the outside cobs 8" from the 4x4 edge and space the rest 16" on center. That would have each cob covering 8" in every direction. Saves a lot of money and I believe accomplishes what you want done. If you want you can drive them harder but I think that's in the ballpark.

 

[ANC]

You need about 60 gal of substrate to hit high g/W numbers, even so, you can fit 4 plants to a 1000W.

Personally, I am running 80W COBs in groups of 3 to fit on a 240W driver.

 

[atriumfall1]

Wow. I guess im gonna be the ass. Why would you spend so much money on this many lights for such a small amount of plants? Unless your ceilings are 15 feet high its wayyyy over kill. Plus the amount of training just to achieve yeild would be a full time job.
