The Chinese Quantum Board Knock Off Builds

[bigmikey86]

Now I got a question! So far I got 3 240w kits in my 5x5. And a 240w kit in my 3x3 all of these are the white only 301b boards. I'm looking at buying 3 more kits for my new 5x5 that's coming in the mail

My questions are-

has anyone used the added cree 660nm 301b/h boards ?

Would I benefit from buying the added cree 660nm boards instead of the all white boards ? It will cost me 150 dollars more to have added red in the tent. Is it worth it ? Or should I just add 660nm strips ? Thanks

I just bought 3 240w kits with the cree 660 built in for my 4x4 set up. First run with them so I can’t say much but it all depends on what you want out of your light. You could grab four QB11 660 strips from KB and a HLG-80h-c700b driver to run them. Wire them in series annnnd you’re done.

In your opinion do you feel like you have enough 660nm red in your garden with just the added cree chips ? Or do you feel like you will eventually add more 660nm ?

As mikey said, last time i checked its cheaper per watt and for spread to get the red separate from the boards. Qb11 for the win, and you could some uv or similar as well.

Looking to get the most out of a single 240w kingbrite 3500k (with seperated heatsink) for now, what size tent would utilize this light best? 3x3x6 or 2x4x5? Id like to be able to upgrade to a 4x4 and use the first tent for veg in the future.

Thanks

2x4 defo, the taller the better.

Great thanks, will try to find a taller 2x4.

How much head space do you have for the tent? A 5 foot tall tent is pretty tight when you incorporate a carbon filter (if you’re using one that is!). I’d try to find a tent with a minimum height of 6 feet. If you have loads of head room, Fusion grow tents makes a 4x2 that come 6’11” and can be extended to 7’11” if needed, the prices are half of gorilla tents. I can’t speak highly enough of mine.

2x4 defo, the taller the better.

If they're put together lengthwise, End to end, 2X4.
If they're put together side by side, creating a square, the 3X3.

Have a question for you all .. looking at getting 12 240w Kingbrite boards. Saw a few people talking about running them 6 inches apart and running them softer like 150 watts each ...is that a good suggestion ? I’m trying to maximize these boards and get the highest grams per watt possible. Any suggestions would be greatly appreciated !!!!

The softer you drive your leds the closer you can keep them to the plants, and the less losses you have to light hitting the walls. 6 inches apart at 150 might be too much light though if you have them that tight.

Whats the size of your space? Are you only after grams per watt or are the totals also important? Generally with leds as your grams per watt go up your total yield goes down. Its easy to do 2g/w with only 100w per tray, all you have to get is 200g but if you want pounds and pounds per tray you need more power and get diminishing returns.

Check out some strip builds and maybe fotops
Spread, low hanging height os your friend.

Also remember to have a plan on how to keep you grow space +80F, a lot of power goes into this.

Yeah one of my tents is 2x4x5, its a pain in the ass with a 8" filter. Have to scrog really.

 

[Osulax2131]

I guess grams per watt isn’t the deciding factor just total yield ..I’m working with 4x16 maybe 4x20.... just not sure if I run less lights higher and at 100% or more lights and run them soft and closer

Get your form factor right to start with. A 2 feet 240 qb fixture doesnt spread the light well to the sides of a 4 foot aisle. Aim for a 3-3.5 feet fixture. Is it open space and would you be able to use lights which are diyed (no inspections)? Then fotops might be a good version: 800 diodes, 3'x1' board, no heatsink needed for less than 200w.

Or figure out another way to hang them, maybe length wise instead of across. For fotop grows have a look @WeedSexWeightsShakes grows

Those Cree's are nice.They actually push the efficacy higher on the fixture. I bought Epi's they don't I think the added red is still the way to go. The Cree's will outlast them too. I almost pulled the trigger on some Geek lights w/Cree's.

Yes it is an open space. I’m open to pretty much anything and yes DIY can be an option. Just figured a bunch of these 240w boards would cover a good amount of space and not be crazy expensive. I don’t necessarily have to have a 4ft wide canopy.

320w kits maybe better. About $240 delivered from China.

Just measured the room seems like I can only fit a 6-6.5 footer anyways, appreciate the advice ill look into fusion tents. I am getting a inline fan / carbon filter aswell, aiming for a AC Infinity T4 or T6. Would the T6 be overkill or would it allow for upgradibility ?

Cheers

More airflow is always better IMO. I haven’t used the AC line of exhaust fans so I can’t speak too much on them. I run a 6 inch hyper fan and love the shit out of it.

So I just bought 4 240w boards with added 660nm wish it was the cree but I got the epistar cause I'm a broke fucker... I paid the lady and then went and smoked a bowl... I'm now watching the news and shit hit me like a tidal wave and I'm like fuck... I just ordered grow lights straight from china.... should i be worried when I open the packages lol ? Should I atleast sanitize them with disinfectant wipes ? What is everyone's thoughts ?

Lol you didn’t get the hazmat suit option at checkout? Duuuuuude.
