Hey guys, here are some pics from the final harvest.

These are two freshly cut cindy's, one on the left of the coathanger and one on the right. The one on the right is the lowest yielding plant of all with 43 gram.

The effect of C99 is like a more mellow version of mushrooms, really trippy and visual.

Some additional trim and larf drying under the cabinet. Kinda looks like a middle eastern market this way.

The trim is plenty sticky and i'll make some qwiso out of it.

This here is a single Lemon Kush, my biggest yielder with 92.3 gram.

Freshly cut ICE

Yield per plant:
C99 #1: 43.0
C99 #2: 67.1
ICE: 74.9
Lemon Kush #1: 92.3
Lemon Kush #2: 60.1

Total yield: 337.4 gram
Max power: 297W
GPW: 1.13 gram per Watt

To get the gram per kilowatt is a bit more difficult. A total of 422 kWh was consumed, but this includes ventilation and also vegging the next generation. For vegging and flowering just this crop I estimate 328 kWh was used. That would give 1.03 g/kWh. That is still a long ways away from the 1.5 g/kWh that Hans is doing.

This is thread I was looking for!!

I am going to use your cab design for my upgrade when I recieve my new lights.

Very well done dude, you seem like a bag of knowledge and thoughts after reading your posts and your cab looks so streamline, dig it!!

Some ingredients for a new grow light came in.
IMG_6541_1.JPG

My recipe is very simple, just add some aluminium T-profile, wiring, solder and silicon glue to get this
IMG_6549_1.JPG
The Mean Well HLG-185H-C1400A driver powers 5 strings in parallel, each string made up of 5 Vero 10's. The trick of parallel driving is to sort the Vero's beforehand by Vf and puzzle together a combination of strings such that the total Vf of each string differs as little as possible from each other.

The light is adjustable from 74W to 210W (230V AC power), or 67.3W to 198.9W LED power. This means the driver at max power is over 94% efficient, which agrees nicely with the spec. The other nice thing about this driver is that although it is rated for 1.4A @ 143V, it will give a higher current at lower voltages (up to a point), so as to maintain 200W output power. For this light it's 1.528A @ 130.2V. It's as if Mean Well thought "hey you payed for 200W so that's what we're gonna give you". Very thoughtful. The dimming is stepless; fully dimmed the current is 545 mA. The open circuit voltage is 143.2V, I touched it and felt no shock.

The new Vero's are 3500K since my favorite, the 4000K, is sold out at Digikey with a lead time of 2 months. Spectrum wise the Vero 3500K compares to the Cree CXA 3000K. The price of Vero's has dropped again, right after I ordered...

Here's the new light in my flower room, had to take out the older red-white-blue strings.

The older Vero strings are now powered by a Mean Well too.The two Mean Well drivers have replaced 10 cheapo drivers. Total flower power is 385W (AC) / 362W (LED) of soft running Vero's. In such a small space that is just... bright. I thought it might be too bright for the plants but no they are insatiable.
IMG_6573_1.JPG
I like it jungle-style, so again a dense canopy that is inching towards to the light. The canopy temp is reaching up to 31C. Since I'm moving towards a perpetual harvest the plants here are in various stages of flowering. Flower development can be observed almost realtime now.

Also check out the spread of light, specifically the lack of harsh shadows.
 
Newark has the best price I have found on veros. Last I checked only mid 30s on vero 29s. Also, the have a 10 year warranty as of the 15th of this month.

I thought about the series parallel on the hlgs but ended up going for cxa 3070 on 1050As, as I was concerned about possible runaway. Great design, can't wait to see the results!

What variations in vF are you seeing?

The DIY'ers in this community are really some of the best around, very nice work again mr flux. You guys are at the cutting edge compared to us pre-made led panel buyers; not even the same league with the #'s

Really don't wanna get my hands dirty:eyesmoke:...........but god damn these grows are starting to sway me

I can't wait to get my new panels but already a little piece of me regrets not diy'ing, next pay I might buy some cobs and start tinkering.

Nice work Mrflux, gonna copy your cabinet as well, you own!!

Those good prices at Newark must be US only. When I go there it says that no pricing is available on the Vero's. If I select my country (NL) it goes to farnell.nl where the Vero's cost 3x as much as at Digikey...

I'm seeing pretty even heatsink temperatures, there is not really a chance for thermal runaway to develop. These white LEDs are just not very temperature sensitive. It might be a problem for red diodes with bad heatsinking. Good luck on your CXA build!

The range is from 25.6 - 26.8V @ 292 mA.

I think that's very true, with DIYing you can get great numbers both as wattage and as efficiency. This light would do 1.8 µmol/J. There's a total of 900 Bridgelux 1W diodes.

Why not start small. Just an eensy little companion light. It's totally harmless, really. It's not like a gateway light that will drive you to build bigger lights, honest.

Sure, sure...thats what they all say. Next thing ya know...

This is impressive, to say the least. I'm with Psuagro...you are tempting us big time with your DIY LED awesomeness!
