2 X 2.6 = 5.2V
Etc.
Do not exceed Vmax and do not power-up without a heatsink.

I have no experience with buckpucks.
So document and we'll learn sumpin', yah?

2 x far red:740nm, 5w, 2.6v, 1a
1 x blue:440nm, 5w, 3.6v, 1a
2 x power supply:24v, 6.5a
3 x 3023-D-E-1000PmA Wired BuckPuck (one for each color)

i wanna wire the deep reds on one buckpuck, the blues on its own buckpuck, and same for the far reds. i wanted to wire the blues and deep reds on the same power supply(the attachment shows how i would wire it). would this work for my situation? also are the amps in the power supply a bit much?

ive been really confused about how many leds can run on a driver and how to figure it all out. if anyone could help out that would be awesome.

weezard mahalos again brah, i hope you dont mind all my questions. and if anyone else beside unko weezard get any input on my idea feel free to comment. im really interested and wanna learn about this.

R=red, FR=far red, B=blue, *=spacing between leds. the forum wont let me post with spaces in the beginning of lines.

this is how i would place them on the heat sink.

**R*R**
FR*B*FR
**R*R**
would this probably be the best layout or should i lay them differently?
far reds only come on when flowering(1hr before the lights turn on and turn off 1hr after, then 1hr before the turn off and 1hr after they turn off. do i need more far reds? is the time i would be running these sound about right?

I do not know.
The timing is right but I can not even guess at the R:Fr.
Mo' betta, run that by KNNA.

It is my experience, that 4. 660nm. and one royal blue are ideal for blooming without the 740nm.
The 4:1 ratio actually promotes stretch, and early flowering in veg.
So much so, that I had to switch to a 7:3 ratio array to keep it from happening and to shorten the internodes.
When they are ready to flower, I'll go back to the 4:1 Ratio.

That's why I use a dimmer on the big array.
I just turn down the reds for vegging and can adjust internode length to my needs. 3:1 makes 'em short n squat.
Then turn them back to their maximum of 5:1 for flowering if they have the headroom.

would this little panel even have enough total power to grow 2 plants about 20" tall in a small box?
Not really.
Mo betta grow one plant right. The yield will be about the same as 2 plants because of the crowding effect.
(They read each other's reflected far red and compete, makes 'em spindly.)
And a 6.5A. power supply will run cool and happy with the light loading.
It also allows room for future expansion.
