Same here with a pair of Vero 10s on a cheap <$3 300mA driver. I havent got my Veros all on the HLG driver yet still waiting for friggin fasttech (slowtech) cheap driver for single V10 driving to test vF and "bin" them that way to match sets of 5 up. I had probed pos and neg and with the plug...

For pure veg Id do 5000K but 4000K would work too.

Should have got a drill press, now drilling and tapping 84 holes by hand bongsmilie

Ya thats pretty shady how they did that switcharoo and still havent changed the info and pics after all the business they got they shoot themselves in the foot now by trying to sell those decievingly. I think of all the times we have suggested and linked those drivers in threads and people see...

If its a Constant Current driver (CC) then it will output 1420mA at any voltage within its operating range of 32-45V DC, the COB used determines the vF not the driver so the COB receives 1420mA at its forward voltage (CXA3070 ~37V @ 1400mA = ~52w). Those drivers should work fine and run either...

Turn it into a COB beast. That driver in your picture (output 32-45V DC, 1420mA) looks like it will power a CXA3070 or Vero 29 at 1400mA or around 52 watts if you wanted to go that route, looks like you have 8 of those drivers in there from what I can tell in the pics.

So is this the newest spreadsheet? The numbers are a higher than the one I was going off of.

If your source for ABs you are talking about are 60% more than Z4s it is not worth it IMO. Z4s at 1050mA have just a slightly better efficiency than ABs at 1400mA so that would be a good choice (Z4s at 1050mA). At the same drive currents ABs are ~3% more efficient than Z4s but driven a little...

Also some pics I took of the visual spectrum differences side by side when I was looking at the spectrums to help decide which to go with. All are Vero 10 80CRI versions. 3000K vs 2700K 5000K vs 2700K 3000K vs 3500K 4000K vs 3500K

Ive got a few Vero 10 4000K that Im going to try on my new build. I do half my veggin in the flower tent due to extremely small veg area so that in part and also due to wanting to reduce stretch a bit over my CXA 3000K setup. I had bought 1 of each 2700K 3000K 3500K 4000K 5000K and was thinking...

Check this beauty grown under 3070 ABs and small amount Luxeon and Cree red & blue 20mm stars. It was a test grow for Connoisseur Genetics new strain Chem D x GSC forum cut (reversed) they are feminized seeds a direct cross of two highly regarded clone only varietys and are being released in a...

Those buds are from Rare Dankness The OX. I just started germing my 4 Starkillers last night. Thanks for the compliments though it is good stuff.

Anybody got pics of Starkiller? Ive got 4 seeds of RD Starkiller and going to pop them all along with others for next run. Heres some RD The OX buds very nice kush smell with just a hint of blue from the Blue Moonshine involved. The smell translates exceptionally well to the taste which I...

Can I accurately test the vF of COBs with two in a series string on a single driver? The only driver I have the min vF is higher than that of a single COB so it can not run one at a time and before I order a cheap driver to power single COBs to test vF I want to make sure that it would even...

I was wrong on my wiring idea for the 35x Vero 10s and now that I thought that through and figured that out, rather than wiring the COBs across different heatsink bars I changed the plan from 5x 32" bars with 7x Vero 10s per bar to 7x 20" bars with 5x Vero 10s per bar. Still one 50mm fan per bar...

The fan sticker on it says .1A 8cfm just tested using it on an old 12v supply for a Remington electric shaver that died on me a couple years ago, actually its the power supply for my DIY colloidal silver gen. Im sure its not the most efficient supply, I plan to use a MW LPV-35-12 for the 12v...

Ya, I tried it on a 24" heatsink of my veg light but it was running at 1-1.1w dissipation per inch of 2.08" profile and staying cool with the 50mm so Im going to try on 32" long at 1.15w dissipation per linear inch of heatsink. Then I can see if the single 50mm is still effective for the extra...

Tested out a 50mm fan on one of my 2.08" profile veg light just put in the middle of the bar blowing down into the channels with blue painters tape over the top of the fins forcing the air down the length of the bars and cranked up the dimmable driver. Left it for about half hour or so and the...

I havent used their blend only tried a little packet of white clover and I liked the results so next is a cover crop blend for me. From my looking around a little I think that if your ordering a build-a-box kit of amendments from BAS then getting a few cups of cover crop blend wouldnt be a bad...

I used some fish hydrolysate and fish emulsion I had around for the N part. Heard the urine works but didnt want to pee pee on mine really.
