Hey, that's timely; that's what I worked on this weekend. I used an ESP8266 board and a 2N3904 transistor. The ESP's GPIO PWM turns the transistor on/off, dimming my Meanwell driver. I installed ESPEasy firmware on the board, and can now dim my Meanwell drivers via web requests/mqtt. It's working great so far!

yea @Black Thumb it can done if you know how to code and solder electronics. I have a hard time getting there, but it is all open source and large communities like this one to help you along. There are also programs that users write for garden automation that they share freely, quite a few intelligent people out there

I have 7- 260 sets (304, 3000k) and have 9 more on the way. All will be used for flowering. I noticed a few posts about 2700k being a better spectrum for flowering. I have switched the order for the 9 to 2700k 288 boards. But now I am worried that the 7- 304 3000k boards I already have won't be as good or somehow be comparitively deficient next to the 2700k 288 boards. Should I try to trade the boards I have for 2700k 288 boards. The area is 8'x16', 8- 4×4 scrogs.

don't stress so hard about the color.. 2700K, 3000K, 3500K.. all work well for flower... 3000K 90CRI seems to be the most recommended if you look around..

Hello all.

Planning stages on my grow cab. Interior dimensions are 45" wide, 21" deep, 70" tall. Planning on two plants Scrog.

I just got a HLG 65, my goodness it is bright. Do you think this is enough for the plants. I would have bought two but it looks like they sold out. Looks like the QB288 will be back in stock this upcoming weekend. Think that would be better?

Thanks!

The 3000k work just fine, not a big difference between them and the 2700k

It still doesn't compete in light quality, at least at retail box stores.
You are stuck with yellow ass "Soft white" or glaring blue "Daylight" (which is 5000K?)
One has to look far and wide and usually order from a led specialty site to find something like "Natural White" or 4K
