Suppose I am already down and out on this one, but I have to finish this project. Maybe sell it off or use it to grow legitimate plants, I think that would still be quite a kick. If it is no longer used to MJ, is it alright to continue a log of the build for use with solar panels as informational? Would like to contribute some info and experience to this board as many other contributions have helped me.

Got some heatsinks and nice MCUs, looking into some MOSFETs to drive the LEDs with PWm handled by the MCU. Roughly looking at 135watts total.

Anyone have any experience with constant current ICs, the real efficient all in once packages from linear and maxim? Looking for circuit ideas that optimize efficiency.

Thanks again!
That would be a very useful thread
We have folks here who live "off the grid".
Your input would be much appreciated.
It's one of the reasons I keep futzing with the LEDs after m,y needs are met.
I love to help get a PWM setup running.

Am under educated and under budgeted, but I do have spare time and a talent for electronics.
Also mess around with DWC. and am giving serious thought to GIC, (Growing in Clouds).

The last bubbaponics module was a 5 Gal. bucket with a screw-on top.
No water pump, no timer, just a honkin' big airstone and decent air pump.
Drilled a 3/4" hole in the top and mounted a 5" net pot filled with Hydrotron clay balls to the bottom of the lid.
Tied 12" lengths of cotton string all around the bottom of the pot and filled the bucket with nutes so it just wets the strings.

Not critical, the bubbling keeps the strings wet, the strings wick water up to the clay and the clay draws in enough water to keep the roots happy until they reach the water.
It's a tight system for vegging, you can leave it unattended for weeks.
Come flowering I'll use the "Bubba-res" that I mentioned in Opies fogging thread to keep the water level constant and an embedded tube w/valve for sucking out the old nutes.
The res. hose will then serve to add the new nutes.
At least that's the current plan.


Let me know how I can help.
