Independent.Did you mount the two 288's together or are they independent? If you mounted them together I'd like to see a pic please.

Does a plant only have one Cola? Or are all nice big fat buds colas?There seems to be a lot of " HID LIGHT " thinking when building rigs for set spaces.
It makes ZERO SENSE to outfit tents with 900 w rigs ... The efficiency of the boards design trumps ( hate that fucking word but ... ) building mega rigs. For enclosed tent grows there is better results with smaller builds as the reflective nature of multipoint lights will grow your plants better.
@ttystikk brought up the chart that best shows there is a range or plateau were high PPF brings less desirable results. The Quantums are far more efficient than the old bulb way of thinking. Growers have grown full plants with one board ( me ) with a lousy 50W driver in a 3x3 ....... use HLG recommendations for coverage and you will be golden.
I see no reason trying to shoehorn a 550 rig into a tent. A balance of power / efficiency and eviromental temps is the key.
Some on here are complaining about temps ..... Which is crazy ... If you dim down the power slightly , the boards ACTUALLY get more efficient. These are NO WAY THE SAME AS HID.
You will get great PPF measure at around 18" from canopy. , if you allow adequate airflow within tent , the tge light penetration will push thru plant. A properly lit tent will have very little shadow areas. No movers needed , no spinning fucking plants or much adjusting.
My rigs have a static height that NEVER CHANGES ... I have Rachet ropes but I don't use them. I have over a 20" of ceiling space in each tent for cooling and airflow , I check for a proper negative pressure in tent and let it go. For " OPEN SPACE " growing is where large light rigs will shine with a larger footprint and optics. I grow with around 300w on any one rig ( and am able to go higher but no need ) I let plants tell me where they are comfortable- if I get praying or " horizontal leaf plane " then I leave it.
Me thinks people like taco and crispy leaves to show they got the juice , lol
You will find also that plants will grow more uniformly from corner to corner within tents as there is really no more " hot spotting " . With a little LST / Supercrop/ etc. you will find tops grow together without much effort.

Here here mean with dimmerThis was the other direction I considered for my 4 boards. 2 x qb288 and 2 x 240h-c2100b. Run one pair for gentle babies then turn on the other pair for something meaner. I decided to just be mean, with a dimmer.
I'm not sure what you refer to by "linking drivers". My recommendation is to watch some of LEDGardeners or Growmau5's YouTube videos. There are a couple with driver fundamentals you probably need to understand before you proceedHere here mean with dimmer
So they are a good option for what i am doing Jedi?
Also i saw a guy who linked deivers together minimising plugs and dimmers (am i right?)
Dont want to go and order to find out I have the wrong stuff
Thx again
I think your right unless the area is a elongated?? shape.I'm not sure light movers may be as productive as they are with point sources that would have fixed shadows without movers.
The diffused light we produce with COBS and strips kind of hits all the leaves from all angles anyway.
I LST autos mostly ... It allows the inner bud sites to grow out.Does a plant only have one Cola? Or are all nice big fat buds colas?
Why don't you get rid of those yellow leaves?
Pop wants to run the boards full bore with a light mover. that way the center of the space doesn't get a full photon blast at all timesI'm not sure light movers may be as productive as they are with point sources that would have fixed shadows without movers.

Stay away from the alibaba bullshit it’s not worth itHow much money is saved by doing DIY qb's vs buying a qb? I was looking at the HLG 550 but those cost 1050$ each, how much would it be in general to DIY (like a hundred$, 500$?)
Also, how difficult would it be to DIY an HLG 550 on my own / is there a guide?

tru dat stay away from chinese knockoffs on these.Stay away from the alibaba bullshit it’s not worth it
