So here’s some more pics.
I’m letting them do some cannibalism to recoup nutrients that went to branches no longer viable because of height/ light
As for the power on the red LEDs.
There’s not much power, so my clamp meter can’t read it. But I set it to 35.2v on the supply. 16 in series and 15 rows in parallel. So my math says it should be around 10.5 watts.
The supply is good for 350 watts. So I’m really not nervous. No need for current limiting resistors either because this power supply holds set voltage without any measurable drift. Though I’ll be adding a meter to keep an eye on it in the future.
I plan to wire up many more of my spare LEDs to create a nice and central power system. The quantum boards are definitely the power house. But I have thousands of dollars of old led tape. This stuff is super bright and has very similar light output to modern day grow lights. So why not!
Here’s the cut sheet for my old red diodes:
