That would be a total load of ~14.4 amps.

Will a Mastech 3010 drive a load like that?

I know it only goes up to 30V.; tried it. So, I assumed it would only "go up to" 10A. :i feel stupid: But at a lower (like 10V.) voltage will it put out up to ~30A?

I don't have a 10 to 12 V. dummy load (or do I?) that'll take 14A (and survive ) to test this. Weezard, I noticed in one of your burn-in photos the Mastech was running at 10.6A (thought I was seeing double :stoned. How much higher will these things safely go? Could I drive a dozen well-matched hi-power leds at <12V. with one?

Watching your progress intently, Hermie.
In other words, Frayed knot.

10.6 A. is just about max for da Mastech 3010 at any voltage.
Put a clone in to preflower streatch and as soon as it started "reaching"
I turned the reds down from 5:1 to about 2:1 and the stretch stopped.
I would think that lower light overall would increase stretch?

So, it looks like it will be easy to control internode distance with this design by playing with the R:B ratio.
Got some more fans today and some 6" dryer hose.

Be back tomorrow.
