Be glad to share what I have learned. I must say as a, how to say it, seasoned grower (an older guy), that I have not IMed. So you pick the program and I'll install it! Thanks. (I do have gmail)

BTW, that Skunk 11 came down about 12oz! A personal best per square foot. And about 1.38g a watt at the panels (that's with Vero29s not the top-of-the-line CXB3590s, so it could have been even better). And that with 15 PAR watts a square foot and 3500K cobs all. Many say that's a sweet spot temp wise, and comparing that with many HPS grows, I would have to agree. And by personal experience now!

I have a shit ton of CXB3590 3500K chips running @50W in my light modules, so it eases the pucker factor greatly to hear you say that.

I just put two modules or 8 chips into my veg area and I'm pleasantly amazed at the difference in production.

I'll be installing the rest of them over the next few weeks, I can't wait to see how they perform in the blooming environment everyone says is their strong suit.

My personal best is 26.25z, not a fluke as I just pulled another that came out to 25.5. I really believe I can come close to doubling those numbers once my upgrade program is complete.

I haven't tried 3000k or 4000k, but I'm very happy with the 3500k. Supposed to be a good seed-to-weed temp. Another tidbit I remember is that it's 90% PAR photon count and 10% spectrum. I think that is true.

A few details on your 25 and 26 oz grows?

Here's the big one;


RDWC, vertical, currently using 860W CDM x five lamps and six plants per rack. They actually pull 1100W apiece from the wall, for a total of 5500W. Upgrade in progress to 24 modules of 4 CXB3590 @50W apiece = 5400W as each module pulls 225W from the wall. Same 6 plants, each on the same 4' x 6' tall trellis. I'm aiming for three pounders.

What a beast! She looks to be over 6 feet tall! Do you run vertical lights now?

I like the 4 cob bars. The ultimate in flexibility...IMO. Please share the detail...driver, current, heat sink, optics, holders, etc. I'd like to know and it might be a help to Herbal E as he prepares for his build.

I guess my questions are somewhat confusing because I'm still confused myself, sorry.

-the reason I'm asking about 4000k (and higher) is because GreenGeenes did a run with 4000k vs 3500k
and he said he noticed main difference in shape but not in quality or production.

if I understand correctly the higher you go in Kelvin scale the more efficient you get
and even wiki says that full spectrum (sunlight at noon) is 5000-5500k

are there any other documented grows of lets say 3000k vs 5000k?
in regards to yield and quality, please link if so. if not It seems like I will have to do it myself.


@64%
(8 ) CXB3590 3500K CD @ 700mA (23W ea) passive cooled
(1) HLG-185H-C700

so what is the next step? what would it take to hit 70% ?

just converted the bathroom to clone\veg area

plants after I took tops as juicy clones

the clones


I have idea for my build
I'm thinking about creating a non moving light mover that may also help with heat dissipation
but first I need to know if turning cob on and off every few minutes will wear him out faster or maybe actually increase its life..

BuddyColas explained me almost everything I was confused about in a few minutes.
thanks once again for your time!

It's funny that only after we learn, we see that everything was laid down in front of us all along

so it seems that if we want to get higher efficiency we need to go with the "@64%"
make it double and use a dimmer to drive all panels super soft

I still don't understand why 3500k is considered the most acceptable though.
If plants like photons, why not use 6500kelvin chips because they are the most efficient.
or at least the 5000kelvin as it is much closer to "pure white" thank 3500k
thoughts?

I asked Jerry if maybe I can use one bigger driver to do the job instead of using a bunch of MW240-H

I will also ask Cree about the impacts of turning the LED on and off at diff time intervals.
for example
running a pair of cobs, each cob runs no longer than let's say 30 seconds.
so in theory he will not have time to warm up thus running at max efficiency. thoughts?

If ill not get some answers soon i'll start nagging in your inbox guys!

thank you so much for your time

Glad things are beginning to make sense.


As for the perfect 1 temp cob for seed-to-weed, there is some debate. But the higher K more efficient cobs, like the 5K and up have too much blue for good flowering (that will cause some debate also). But MOST think that a 3000K or 3500K come closest to the best 1 temp cob. And though I have only 1 cob grow under my belt, I do know what good looks like from HPS, and an all 3500K really works well…and at a fraction of the power and heat I used to use.


https://www.rollitup.org/t/greengenes-garden.839682/page-105

Check out post 2086. These guys are killing it with all 3500K…it really works…just saying. GG also has some great pics of a 3K, 3.5K, 4K and Apache grow side-by-side.


Also, with adequately sized heatsinks, you wouldn’t have much temperature droop and need for cycling cob bars (in my opinion). Very little return on investment for the money spent there.

Buy good heatsinks and drivers and know that technology is moving fast and in a year or two you will likely be running some newer cobs that are even more efficient! But the heatsink bars and the drivers will stay. I like the bars over boxes because of the spread, but you can see some pros using multiple boxes, in post 2086 above, to good effect.


I see you are a fan of DP seeds, me too. They have always performed beyond my expectations.


Glad to be a help. I do think after looking around that this RIU LED lighting section is at the forefront of the DIY COBing. So you are in the right place.

Looking forward to seeing those girls flower out after using defoliation.

watch greenegenes tech talks on youtube he talks about the color they are long video but watch all of them and all of growmau5. its about photon density being greater at that color if i remember correctly.

More photons in red, photons have more energy in blue. Simple.

Here is that post from GG on using 4K cobs...as found in:
https://www.rollitup.org/t/cxb-spectrum-vs-output.894704/

Thought you might want to see this before you pull the trigger...
Also another good thread by Supra


Post 9 from GG
My experience is with 80cri 4K, and why I am asking. 80 cri 4K on certain strains has noticeably less bulk and size of buds. Some strains there is no difference at all. As where I have been getting consistent development from 3K and 3500K.

The 80cri should have a more red shift overall vs 70. So I'm just curious since they are doing testing, why not. They are cool guys.

do you have a grow (same conditions) without the extreme deleaf? my personal experiences push me away from it. I'm interested in your results

@BuddyColas It seems I'm starting to grasp the picture. I'll probably go with 3500k for flower and maybe 4000k for veg. all @700ma.

@Ryante55 yeah, watched it like 5 times already

@ttystikk thanks

@Thorhax no, not the same conditions at all. I'ts my first time growing in this place with this strains. the only thing that stayed the same for me so far are the light.
anyway. the average outcome is known (without deleaf).
alot of big growers do extreme deleaf and it works for them.
the technique fits good in heavy packed areas with a lot of plants.
I don't know if it really benefits the plant itself or not but its doing wonders for your room overall which is an excellent trade-off that may increase performance for some types of situations. I'm still learning..

Every COB I own is a CXB3590 3500K and the first place they went was into veg- where they're outperforming everything else I've ever run plants under... So if bloom is their strong suit, I'm looking to be amazed!

its better to find out for yourself than listen to others. maybe next time you could have 1 or 2 control plants in the deleaf experiment.

still really impressed with how happy your plants look=]

Great pics. I like the way you have remodeled your grow room…like having the outer row of LEDs angling in. Some guys have their outer light bars angling in like that…less wasted light. And the girls are starting to fatten up...and "amber" up! Will you be doing a last deleafing or ride it out as is? I don’t see many stems to get a thumbnail on, mostly tight very productive bud leaves.

I was thinking another good reason to deleaf for you is that with 70% RH you can cut down on the chance of bud rot.

A couple of questions...what is the average height of the LEDs above the canopy? And how tall is the wire fencing top to bottom? Thanks.

this is true, will sure do some experiments later on with 3kk up to 6.5kk as I will probably use some of the panels to light up my office.
It's the first time I'm trying this and I'm very excited to see the outcome. after that we will decide if we really need a side by side in the exact same conditions. I guess why not.
though they will have to be identical clones, and my moms are not really ready yet.

Thanks. hearing you guys say it looks good really widens my breath, not only its my first time with extreme deleaf but its also my first time with these strains and only my third time growing at all.
yeah. its true, deleafing increases airflow, drops temps and drops humidity. check this dude out, he is doing it big time and not even making a deal out of it. he is a really tight grower :
https://www.youtube.com/channel/UCDY8sQMuA9Hfx_5w-8J4afg/videos

I don't think I'll deleaf that hard anymore
but there are still ~30 days to go so i'll sure remove some big leaves at some point.
I'm planing to ditch the fence and convert each bed to individual scrog unit
to increase branch spread
I have wheels on the beds so managing and watering is pretty simple. pics soon

all the plants averaging a height of 2.3 foot (70cm)
the height from the panels to the plants is minimal. ~0.70 foot (20-30cm)

I checked out some of the Grand Master Level’s videos. His “Growing Bubba” series. To say he does an aggressive strip at day 17 of flower would be an understatement! Like no stem left behind! But it really works for him getting 2 to 2.25 pounds a light. My impression is he pinches off any leafy fan as needed after that aggressive strip. I did not watch all of his videos, but did you see where he does an aggressive strip in veg or after the day 17 flower? I would have to watch all of them to be sure. I know you did one at day 17 and 27 and they bounced back well from those.


I figured I’d try the 3AL model and do one strip in veg with my upcoming plant. I did and 7-10 days later you would never have known I stripped it. And the nodes are nice and close. I’m liking their model of growing. And they allow 4 square feet per plant…more to my liking.


And good on your LED panels being about 20-30cm above the canopy. I have several small strings hanging down from my heatsinks that are 8” long. I like to keep my COBs naked and up close to the girls!


Anyway, great to learn from your grow and see those bud sticks fattening up!
