Called the well people and they are looking up the results from when it was drilled, otherwise its about $475 to have a complete test done, and another $175 for heavy metals.

I did have a new 280 foot deep well drilled in approx 2002 so it was tested then and deemed safe to drink. The previous well was drilled in the 1900,s and had some nitrate contamination from the chicken ranches that used to be here. The previous well casing was letting contaminants in from...

I've already thrown plenty of money away so if the r.o.would make a big difference I'd go for it, don't tell me I need a cell phone though!

I just bought some on amazon, came with the knob, worked good, i also got the resistors and put one in but really don't know why.

What's in your water? I do r.o.for the drinking water but I have drank this unfiltered water since I was born less 5 years while I was moved away.(That may explain a few things....) Up until about the 80's we had no filtering system. Not discounting what you are saying but my outdoor gardens...

The water I use is well, is 400 ppm high in calcium. I did give them a very light feeding of mega crop though so that may have helped. I'll prob brighten them up again and see what happens.

I have 4 qb120's in my veg area about 3' x 5', approx 18" above the canopy. The girls were looking a little yellow at the tops with leaves drooping. I dimeed them way down and 2 days later everything is perking up, I guess it was too much light at that distance.

Here are some pics of all my homemade lights so far. First two are the new one at 194w and 30w. next two are of my "light bulb light", the first one I made, next two are qb288 fixture. Pic 7 is the first cob light with the cheapo full spectrum chips, last two are a qb120 fixture, I have 6 of those.

Wouldn't it be good to line your cab with reflective material?

Works good now, thank you, dims from 193 watts to 31 watts.

That would be alot easier, not sure why I thought they needed to be in parallel with that driver, is the 18 ga wire that I have soldered to the cobs big enough?

I think I'm better at building the enclosures... So finished up, turned on nothing blew up but its not very bright. Dimmer is working, unplugged that to see if it changed the wattage, no, only getting 57 watts. The leads from the driver show 140 volts dc, those were attached to the terminal...

Sk1 is close to being dry, will get it jarred today. Killed the light on the crystal friday night, cutting them this am, that will be 36 hrs of dark.

Somewhat, I usually get the details drawn in autocad, then my programmer converts that to the flat layout to laser cut.

It helps to have a sheet metal shop with a 5000w c02 laser, the enclosure is .06" 5052, the heatsink is leftover from some job.

Mines pretty vanilla compared to this.

Thanks, it's still looks like a rats nest with all the wiring. Compared to the quantum board fixtures these are a pain with all the wiring, I guess I thrive on figuring things out and the build process, I spent about 6 hrs today soldering and figuring things out.

Here is my latest build, the cobs are warm white cheapo's, 100 watt chips, 3500ma max, running at 1400ma. Still need to get the dimmer hooked up. Next up are 2 similar except using luminous cmx 22, going to 9" spacing on the cobs and an A drivers.

Cut the sk1 last night, now the crystal get the whole room for a while.

Thanks for all the info, I just bought some.
