No, the boards connectors are rated for 300v max. 3 boards would exceed that voltage and damage your boards or worse.

Docs say 1600mA max per board.
Also I don't think that driver has enough forward voltage to run 3 in series. 114v max and the board is about 110v. I'm considering running 3 in parallel for 933mA per board about 100w each to cover a 2x4.

Unfortunately id have to have them up to 6" close at some point to make this grow work and I'd really love too. Maybe running more boards at lower watts would help but i rather not have to buy more than two boards and run around 200-250w if possible.

You can always use a dimmer and run with no optics. For most of the grow you won't even be at 6" anyway.

You can run 2 strings of 2 boards on the HLG 320H-1400 sure. I don't recommend running 3 boards on that driver though. Get the 2800 and run all 3 in parallel if you want 3 boards on a 320H driver.

Ryante55 on that driver you can only run parallel as the voltage only runs one board if you want to run series look at the 1050ma for 3

Unfortunately I have to wait another 6 weeks to fill my jars!

This is exactly what I am trying to do. Mind you, I have spec'd out a COB array as a backup (to ease my itchy trigger fingers).

We have the HLG 550 but if you are looking for something different hit us up on PM

My 90 watt kits came with everything you need to assemble a complete light, including a driver that can be dimmed up to 50% (down to 45 watts). Find out what day they will be back in stock and order at 9:05 am

@goodro wilson are those 3 milk crates the footprint under your light?

Yes they are lined with plastic also and filled with a little over four gallons each
On the right side the light is a vero29 all together my cab pulls only about 150 watts plus a little desk fan

Could you tell me a few details about your grow, please? I have a couple of QBs I'm installing in a 2.75sqft x 3ft tall cab... I'm planning on growing micro style with maybe 6-12 plants. This will be my first grow and given my limited vertical height...
I'm wondering how tall that plant is? How tall was it when you flipped to 12/12? And how many watts are you running your QB and how close to the plant?
Should be cracking my seeds in about a month!

Just contact @robincnn, he built my 2 board light, I think it's the one on the 1st page, 2 boards, 165w on full and 22w fully dimmed, $300 all in (or there abouts)... connecting the wago connectors is easy, I just posted a pic of how I'd connected it up in this thread and Stephen pointed out it wasn't wired correctly, so I made the adjustment and sent a pic to Robin and he said it looked fine, so I cranked it up! Working fine so far...
So yeah, Robin will build it for you if you're not a DIY guy like me

I'm working with limited height in a 3x3x4 and I went with the SOG style. Everything is an experiment at this point.
2 boards on a HLG185-C1400A, boards are about 16" away from my tallest plant. I'm running them at 50-60 watts per board right now because I'm waiting on heatsinks. Others are running at low wattages and are getting great results tho. Trying to study the plants to see if they are in need of more light but I suspect they're very happy. All my plants except the one in the pic are slightly CAL/MAG deficient at this point, which to my understanding is a great sign that they are getting a adequate amount of light.
As for the girl in the pic she is my first experiment with flowering a rooted clone. At about 3 inches she showed roots, spent about 3 days under a T5 so I could transplant, and went into the flower room. Right now she is about a foot tall, and about 2 feet away from the panels. I'll be watching but all the plants are doing well at this distance/wattage and everything is on schedule.

Hey mate,
I've got the same driver and 2 boards, but only have 2.75 of floor space, and only 3ft in height... from what I've read running it at 100w will be enough. Given my lack of height, I'm also interested in SOG from clone, would love to see more pics of your grow if you're willing to show them!
How many plants are you planning for 9sqft?
I have a 2nd cab that I've decided to take over, same dimensions... but this one I'm planning on having 2 levels, one will be 11.5" height and the other 21.7" in height. The smaller level will be for cloning/veg and the larger will be for weeks 1-5 of flower, which will then be moved to the 36" height chamber for week 6-10... so I can harvest around every 5 weeks.
Just wondering if you think splitting the 2nd cab into a clone/veg and flower phase 1 chamber would work... I want to get 1 QB for each level
Good luck with your grow.

Here's a pic of the 2nd cab... the 1st cab with the 2 QB boards is the same, except without the shelf.
