DIY with Quantum Boards

Is that all missing? The B driver can be wired in series or only the A? This kit comes with B driver.. Is the only difference in the A and B driver is the build in adjuster?
To my knowledge the answer to your questions are yes. But don't hold me to that I am not familiar with that model driver myself. Best bet would be to ask @robincnn or @Stephenj37826 on the wiring in series, parallel, etc........ but yes that's all that's missing and the difference in A and B is internal or external dimming. B is external.

wiring in series means each board receives the full current and the voltage is split between each board. wiring in parallel means each board receives the full voltage and the current is split between each board. you can also wire in series/parallel

First time builder, much too long reader- looking to make my first light
required: 4 quantum boards, 1 driver (PLC 6 Mindset, best bang for the foot-in-the-door buck)
I'll be using it for flower in a 4x4 space, let's also assume we are talking about the 288, though I'm not opposed to one or the other, and let's also assume due to nature of the "batches" that these 4 boards will never be separated or added to, only driver changed out possibly for veg or something in the future (but I probably shouldn't even be thinking that far ahead as I have 4 SE HPS to replace in total.)

According to LEDgardeners pt 2 video I can use a 320H-C1400 (at 50% max current,) or a 480H-C2100 (at 70% max current(HLG 550 setup)) wired in series to achieve this. I'm definitely leaning towards at latter, but being as this will be my first time building and seeing the things, I have no idea how much it's gonna heat up. It's well worth it to burn more watts vs a small percent increase in efficiency for someone in my situation right? Could I use the 480H-C2100 to wire them in both series and parallel later to run them at 1050mA?

Is 2100mA for the 288 considered soft? Would I be fine with the Slate 4 at 2100? Maybe I should get the Slate 5 just for the better spread if nothing else? (+$15) There is plenty of air movement in my room. Tell me to buy this shit and change my fucking life, I've done too much reading and not enough buying.

Almost 5 weeks in Bloom, Using a HLG 550 growing Aurora Indicia and Bubblelicious in 5g smart pots. the last few days it's been up to 98°when we went through a heat wave. my tents are in my basement were it stays between 68 to 70° Once I put central air on my temps have been no higher then 81° I must say the QBs are doing their job Great! Started making my own No-Till soil, just need to get a few more amendments and cook it. all I do is ScrOG Grows I'm just using a trellis so it's not really a ScrOG but make the squares 3 inches. I rather have just grown one plant the Aurora Indicia in a 15g smart pot. In the future when I build my ScrOG with 2" squares then just one plant. Pic one Aurora

heres a question for those of you who have been using qb/cobs for a while. i just finished the 4th week of flower and i already have at least 75% cloudy trichs. if it keeps on this way its going to be done by the end of next week. is that normal? i'm used to things taking at least a couple of weeks longer under the hps

Go the normal duration.

qb288 @ 25w 20" from the seedlings and they stretched a bit. To prevent the stretch should i lower the panel or bump the amp to 50w or something? I'd prefer to bump the amp cause next to the seedlings there is a mother plant. noob.

With the appropriate heat sink these boards can take well over 100W. You can get most of the way there by aiming a fan at the board for cooling.
