DIY with Quantum Boards

heres some thoughts for you.

first off the hlg 300 is a prebuilt fixture hlg sells which is nice but they also have a diy kit in the same wide configuration. https://horticulturelightinggroup.com/collections/diy/products/260w-xw-qb-led-kit
whats nice about the kit is it includes everything you need to assemble except rope ratchets and tools. and as far as I can recall the tools needed were a phillips head screwdriver to mount the boards to the heatsink and wire strippers to cut and strip the wire for the hookup. now currently as of writing this hlg shows out of stock but no biggie they also distribute to https://growerslights.com/products/...w-quantum-board-led-kit?variant=2764371197980 and thru them for $25 more ya dont need the tools cause they will build it and test it b4 shipping to you.
as for your crees thats up to you if you can find a buyer.

I myself have 2 of these kits https://horticulturelightinggroup.com/collections/diy/products/260w-qb-led-kit which was their first 2 QB kit I ordered back in may 2017 they didnt offer the wide 2 board kit yet. I had originally planned to run 3 tents 2 4x4 for flower and a 3x3 for veg. but reality set in when I realized I currently had the space for a 3x3 tent only and Im barely fitting that in. so in the 3x3 i am using the 2 kits and at lowest output on the 4 boards plus a 2 30w secret jardin fans one blowing up from the center floor and another hanging in a corner on a pole blowing across the fins of the heatsink. and im at 296watts according to the kill a watt and my temps in the tent dont exceed 84. I cant run at full power cause it drives the temps up to the mid 90's, and from the grows guys are doing with the QB's many are not running full blast and are getting great results.

still I would be very interested to see how you do with them.

Does anyone know if this kit https://growerslights.com/products/...w-quantum-board-led-kit?variant=2764371197980 will run in New Zealand with just a plug adapter as we use 230/240 volt as standard voltage here in New Zealand and I think growerslights.com is American based and in the US they use 120 volt.

Id like to buy 3 kits but need to know if they will work as expected in NZ with just a simple plug adapter.

Anyone?
 
well its the drivers that will run the ac not the dealer. and the meanwell drivers are rated at input 90VAC to 305VAC so put your NZ plug on it and dont worry. infact mention to them where its going and they might supply the plug

All I could find there was 8ft pieces that were around $15 each. I'm sure better options are available somewhere, but that was what they had and I got it because I was there.


I see a lot of people running 2 qb288 boards on a HLG-240H-C2100 driver, and am wondering how well that setup works compared to the same boards using a HLG-320H-C2100 driver assuming they are run at max.
 
320 will give you nothing more than the 240H when running two boards. the boards will draw the exact same amount of power from each, according to their forward voltage. The chart shows power draw at each forward voltage and amperage.

what is the problem lately with boards being available but not heatsinks? Isn't about time these supply problems ended? I'm a big fan of HLG and their products, but its long past time for these issues to be resolved, the continuing out of stock issues have become cause for many people who would buy to look elsewhere. WE are the people who got you off the ground, time to reward us with reasonable supply availability. I've built a business from scratch on a budget, I know it isn't easy. Maintaining inventory is critical to continued success.

I am going to order 4 more qb288 so I'll have 8 in total. Going to build the fixture with 6 for the flower area, and get another driver for the other 2 in a separate area. To run 3 off each 320b driver should I wire in series or parallel?

It kills me to see the kits with the heatsinks... but all of the heatsinks are sold out. They must be trying to empty inventory.

Ive been running 16 Cree 3590s in a 4 x4 i.e 1.2metre x 1.2 metre x 2 metre high but i have always run duel layer, i.e i have a table mid height, 8 x 3590s driven at 50 watt each layer, i plant in a table only 15cm deep. top and bottom.

Im considering selling my lights and changing to 2 x HGL 300s.

my 3590s pull around 800 watts i imagine , 2 x hgl 300s would pull around 600 watts,

I keen on the low profile of the quantum boards and the weight reduction.

p.s i live in nz so if anyone wants the 3590s let me know in the next few days

thoughts?

I have the same tent and have been rolling this idea in my mind for a while now. It obviously increases workload and lowers the margin of error significantly. I have already done the split in my smaller 1m tent. Top are my mothers, bottom are vegging plants until ready for the 1.2m. I am also in the process of replacing the 3590s with QBs. At the moment it's 8x3590 and 2xQB304. Waiting on stock like everyone.
Making the change is a no brainer. You gain 10cm of height, at least, that's on each layer.
You might want to consider the new QB132 that's supposed to come back to stock soon. You'll save a lot of money. Just replace each 3590 with a QB132, no heat sink required, no new drivers required. I would personally add another 4 on each layer for a total of 600w. I have QB304 and you can pretty much run them all out as close 20cm from tops and you know you can run the 3590s @ 50w as close as 15cm, even less without reflectors. I imagine you'll have no problems with the QB132s.
An even better option is to go for QB120s. Run 8-10 x 60w-70w. You'll get better spread, still no heatsinks required but you'll have to get new drivers.
When the QBs came out I grabbed a few 304s. 2 of them are now in the bottom layet of my 1m tent. I only use it for veg but honestly it's too much. They are too intense for less then 1m headroom. And of course when I'm 6 weeks into veg and the tent is full, coverage suffers.
Strips are always an option, unless like me, I can't get reasonably priced aluminium channels for heatsinks.
Whatever route you take, mount the drivers outside the tent to lose height, weight and heat.
Hope that helps.

Thanks Down to Roach, If anyones interested, my yield for 8 x 3590s top layer and 8 x 3590s bottom layer of 2 meter tent i.e thats 16 cree 3590s in a 4x4.... 2 metre high tent, 1 metre per layer, i.e i have a 1metre high cheap Trestle fold table in a 2 metre tent with a shallow 15cm growing tray on top. and the other 15cm growing tray sits on the tent floor, ... , I hang my 8 x cree 3590s under the table using heavy plastic chains screwed to the underfloor of the table using self tapping screws and a large washer larger than the chain.. the yield has been between around 19 ounces to 26 ounces every 10-11 weeks with 2-3 weeks veg, from both seed and some grows have been clone.. ive been running either Dr krippling incredible bulk or Dinafem industrial plant. 4-6 plants per layer . my layer trays are 15cm deep but only 90cm x 90cm trays , initially i was running a flood and drain hydroton in the top layer and potting mix in the bottom layer, im now just running potting mix in both for simplicity, but still feed half strength hydro food.. done about 7-9 grows with this set up so far and always average around the same. Ive been working in the horticulture industry 20 years and are a part time hort consultant so growing experience might be a little bit above average. But gives a idea of yield with this setup in a 4x4 duel layer over time.The bud in my avatar is from one of those grows, sometimes ive harvested a little too early due to circumstances. I finger and bend my plant limbs down fairly aggressively near soil level to fill in spaces, and repeat bending till mid flower, I defoliate leaves fairly hard from top down i dont remove any lower leaves near the soil level. The lower leaves are my solar panel and energy/carbohydrates travel upwards to the buds, my plants rarely exceed 40cm- 50cm in height.

Post due to email request for more detail in how ive been growing. Thought i share with everyone.

Currently Im not growing , and there is no physical evidence left in this world that ive ever grown in the past or ever will other than this made up post which is totally fiction written by my goldfishes friend Dr stoner.

Nice guy, i believe but ive never meet him and dont know where he lives

As you were..

After Imaginations ... Dr Krippling Afghan Cow is my go to... now, little bit longer flowering time but omg the weight is insane the weight is worth the wait

I have a qb132 3500k and a single meanwell lpv-60-24 driver. The driver does not have a grounding cable\port on it. So does this indicate that I only need a two prong cable without grounding?

does the ac side of the driver have a green wire? usually the AC power side has a positive , negative and a earth, the out let to the LEDS just has 2 wires a positive and negative... thats normal and is fine..
