You could bend over, fart, light the fart on fire, and use the light from the burning methane coming out of your ass, and it would still make a better grow light than the big, bad Spidey, lol.

I'll do a proper plant pic update with the lights on tomorrow, but here's a couple after lights out. The stretching and bud formation continues on day 21 of flower. Also, I was bored so I decided to post a few pics from around the yard. Pics from the vegie garden include cantaloupe, bell...

That makes me feel better Captain. I finally did the math on my light and I'm running about 604 PPFD, which made me feel inadequate since I've seen the min of 700PPFD recommendation:bigjoint:. But after seeing your grows I don't think I need to change anything.

There are some COBs that run at 18v - some of the Bridgelux RS Array cobs or Cree CXA1512 might work to add some extra light and max out the drivers. Not as efficient as CXB3590s, but monos aren't always efficient either unless you can source some decent bins...

Either the grower is spraying these plants with colloidal silver, or these are the most stressed out plants in the history of mankind.Wow.

I'm also doing some tinkering with some far red LEDs I got today, to build a flower initiator. I ordered 2 2-packs of Far Red LEDs and a Meanwell LDD-300HW LED Driver from LED Group Buy via Amazon. The only problem is the morons shipped 1 pack of Far Red LEDs and 1 Pack of 435nm blue LEDs. I...

My plants are doing fine in the heat - I'd prefer to keep them cooler, but I don't think it has that much of an impact honestly. Plus, they really only get hot in the late afternoon, the cabinet stays in the 70s and low 80s in the morning. I could run the lights at night when it's cooler, but...

Nice job on the cabinet nv! I mentioned this in your thread, but I was pretty amazed this week at how plant transpiration can keep cabinet temps down even in hot environments like my garage. It hit 106 today in my neighborhood, and a thermometer i have in the garage was reading 105 at one point...

That turned out good - nice job! I used to have that same cabinet at my house back in NC, and I used it for a seedling/veg chamber with a high output fluorescent light shining through a cutout in the top of the cabinet. The LEDs should be plenty bright enough for plants, and I don't think you'll...

Start of flower week 3 update: Things are beginning to get interesting in the flower cabinet. I've had to lower the shelf 3 times this week to accommodate the stretch on the Fire OG (on the right) - she's almost tripled in size since the start of flower, and is looking great. Fortunately I...

I'm hoping someone out there who has grown some Sour Diesel before can help me - my Sour D has been in flower for about 2 weeks, and there is zero smell to her at all. She's been a bit of a problem child - slow growth compared to the other clones i have, and she's never had any odor. The SD is...

It's not recommended to do this, but I'd think you could run 4 - 36v cobs off that driver if you wired them parallel. The voltage that each cob runs at would need to be the same, and you'd probably want to add 2 amp fuses to keep the others from frying if some cobs failed. The cobs would run at...

I've got my driver hanging on the back of the cabinet to help keep heat down. I'm really at the mercy of the weather regarding my cabinet temps, since i'm growing in a garage with no heat or AC. It can get in the mid-90s in the cabinet on a hot day, which is not ideal but the plants have...

I sampled the GG4 last night, and it really lived up to the hype for me. Just before bed I took three solid hits of the GG4 from a bowl, and within a minute or two later I was standing there with a shit-eating grin on my face while the high spread through the rest of my body. I got some strange...

How much is the driver you are looking at? I use a HLG-120H-C1050B from Mean Well that will run 4 Vero 29s, and you could just run 2 Veros on it if you wanted, but the driver runs around $60. It maxes out at 1.05 amps so it would drive the Veros softer. As long as your single plant isn't some 6...

It would run 1 Vero 29 OK, but not 2. Vero 29's run at around 38 volts in the amp range of this driver, and the driver voltage range maxes out at 42v, so it can handle only 1 Vero 29.

That's good to hear, since i used Ceramique on my Vero 29s. Only because that's what i had in my drawer - it was leftover from a computer build a from few years ago. Keep up the great work Supra!

Start of Week 2 of flowering update: COB LED work very well – plants each grow 2 new leaves in 1 week!! ! ! ACTION NOW! !! ! ! Lol On the left, the Satori is filling in nicely, but since she was grown from seed and not a very mature plant, she’s taking a bit longer to show signs of...

Thanks for the heads up - I never looked at Dr's Orders before, I might have to make a trip there tomorrow.

Sorry, I kinda confused things with my last comment. I'd actually be using the volt/ammeter to monitor the LEDs on the DC side of the driver, and I am running more than 100 volts on the circuit so I think the first meter you linked would work for me. I'd just need to find a 5-30v DC power source...
