What do you think of this:

It might work, but you'd need a ZigBee gateway since it's not WiFi-based like the Sonoffs.

for this , I can't understand, you know, many clients request us make the boards with 2700k/4000k(half half).we have a idea want to make a individual boards(actucally, we have a design witth 7input for white, Blue,red,D.R,F.R,UVB) To a certain extent, it will come down to personal preference and/or...

Can't wait to see the test results!

That's true. I don't tend to move my plants much, especially that late into flower. I'd think of it similar to a SCROG where you just can't move the plants.

Plus, mixing 4000k and 2700k is like having all 3500k pretty much.

Yeah, unless they're on separate channels that you can turn on/off or dim. I could see using only 4000k for veg with a little 2700k and then switching to 2700k with a bit of 4000k for flower.

Well, I'm sure those manufacturers put some money into researching what spectra work well, but how good their research is is another story. And there is certainly a healthy dose of marketing and cost-cutting. Some people (including Growmau5) say supplemental UVB improves trichome development, and it...

Wow! I'm surprised how close you had them to the plants. You didn't experience any light stress? He's running them very soft (he said 120/150 watt total) so close is great. Start running them at 1A or higher they need a bit more distance. When I let mine get 6 to 8 inches from strips they eventuall...

How about if we put the blue460nm to replace the 660nm?

I don't see the advantage of 460nm. 660nm is supposed to help with flower and bud production.

I don't know what your light fixture is like, but would it be possible to tie the colas to the top of your tent? I've seen something similar with greenhouse tomatoes. I think you still need the stakes, but the idea is you tie them to the top of the tent with string.
