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.

Is this the correct pot for dimming with a meanwell b driver? https://www.amazon.com/gp/product/B016W8Y5DQ/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

I've never grown them indoors. What do you mean by 10/12 is that hrs of light?, it's only 22 hrs.

I think its working, 20 min at lights out, 11 - 13 schd. this is 6 weeks 3 days, the sk1 is nearly done, the cryst cndy has some time.

New pics, I think the sk1 may be done... only 6 weeks and 3 days, 90% + of the hairs are red, buds rock hard. I'm flushing and letting go 1 more week. The crystal is looking great but still has a lot of white hairs, really solid though. I think the 11- 13 light with the far red is an improvement...

I've had mine at 11/13 this run, looks really good. I think the 11 hrs really makes them think its getting late in the season, time to pour on the sh... Tonight all the sk #1 are bending over, tied a lot up to supports. I need to get a better support system, its really nice without any until now.

https://www.rollitup.org/t/what-about-this-light-schedule-with-far-red.953779/page-2#post-13993085 My sk #1 & crystal candy that get 15 min of 730nm at lights out, has been 41 days and the sk #1 seems like it's pretty far along. The crystal candy seem to be coming along slower.

Hooked it up to the kilawatt and the range is from 94 watts to 290 watts, I let it run for a while last night at max, didn't realize it was that high, got pretty warm. I could hold my hand for about 1 sec on the driver or heatsink, at 94 watts everything is barely warm. I now have it set to 180...

We have a machine shop and this was leftover from a job. I've got about 12' left, that the cool thing about a shop thats been around since 1969, theres alot of "stuff" that is handy to have. heatsinks are somewhat rare though so I was happy to find this, I have been scrounging for heatsinks and...

Here are some pics. I dimmed the red and blue light for some, hard to see the details cause my camera isnt as good as some of you guys.

I think the far red is speeding things up or???? My skunk #1 has really compact buds and most of the hairs have turned red, it will be 6 weeks on sunday. One in the back still has more white but still pretty red.The crystal candy's look really good, some hairs are red, more what I would expect...

here is the qb288 fix I just assembled.

Not really finding one with a fuse that I could change, I only wanted approx 6 amps before it blew, 4 meanwell hlg-120h-48a would draw about 5.6 amps.
