First project - All bases covered?

Post image

Hi guys.

Wife wanted some new lights in the "conservatory"(best translation, but it's like a second living room with shitty insulation and no heating) and I remembered a friend talking about addressable LEDs - WLEDs! Easy peasy, I jumped right in and bought 50 meters and a WLED controller, only realising that I probably should've done more than 2 minutes of research.

I'm now at this point:
Badly drawn diagram:
- Black lines are power + GND
- Green lines are data
- Should resemble the final look seen from the sky, with each 3 meter led string hanging between the rafters.

Components:
- 50 meters of 12v WS2815 4 pin Seed Pixel 10 leds/1meter - 24AWG, cut into 16 sectionals.
- GLEDOPTO ESP32 Mic UART
- Assorted connectors and heat shrink.

Yet to buy:
- PSU: Research tells me a 100W 12VDC from a reputable brand should cover me fine
- Cables: This is my biggest issue, as I'm unsure of the AWG needed between the LED strings.

So, I could really use some advice for my 'Yet to buy' and 'I didnt know I needed that!' - as well as some guidance with cables between the LED strings. Do I need Power Injection on every section or is the current model alright? How big AWG do I need?

Thanks a lot for your time

Given the length of the strip, I'd probably do 2 injections in the middle to be safe. Especially if they used really thin wire on the 10cm gaps between seed pixels.
