The HLG series is encapsulated in silicone(?). Not worth trying to get to the PCB for repairs.

wiki: "Pyrex (trademarked as PYREX) is a brand introduced by Corning Inc. in 1908 for a line of clear, low-thermal-expansion borosilicate glass used for laboratory glassware and kitchenware. Pyrex sold in the United States is made of tempered soda-lime glass; outside of North America the...

From the American Institute of CPAs: http://www.360financialliteracy.org/ No high school student should be given a diploma without demonstrating knowledge of compound interest, IMO.

I have a deep plastic shop sink and keep a solvent tank next to it containing two gallons of Simple Green and two gallons of water. Works great for a 16 inch bong. My solvent tank: http://www.irisusainc.com/p-613-ucb-fb.aspx

I got worried when the brown phlegm stopped. That means the cilia in the lungs are laying down and not bouncing back up. A year ago, it happened to me so I quit smoking for a month and now I'm back hitting the big bong and doing the morning brown lugee. Forty-five years of bong hits and I can...

Move to Nevada?

Tweak it with the power on. There aren't any bare conductors in there (the HLG guts are encapsulated). Pro tip: keep one arm behind your back and don't stand in water if you're afraid of being electrocuted.

I'm glad my drivers are adjustable for current. I keep building more COB luminaires but I don't have the ambition to expand my grow. The HBG's just got turned down to 45W (from 55W) at the wall. I'm heavily invested in Cree but I wouldn't buy it today, based on what I've been reading...

The WA state rec stores carry kief and hash but it's a specialty item, just for old hippies like me, I guess. I don't patronize the stores very often (47% taxation) but this is a good blond for $35/gram including tax: Leafly.com menus will list this stuff under Concentrates but it can be hard...

I use the pain test. I grab the heatsink with my uncalloused fingers. If it hurts before a second has elapsed, things are too hot. (Of course, if the COB is incorrectly seated the heat will not be transferred to the sink.)

I'm sure it's not recommended but I scan the COB from a couple inches away and grab the max reading. I installed a thermocouple on one luminaire and results were similar. I want things below 85C; I'm running CBX3590's.

The Luxdator uses a three-in-one style of dimming like MeanWell, I believe. From MeanWell: "Output constant current level can be adjusted by applying one of the three methodologies between DIM+ and DIM-: 1 ~ 10VDC, or 10V PWM signal or resistance." Luxdator is providing the 12Vaux for a DC...

I had red/blue/white dials on my Lumigrows but never really used them. Putting a 5000K COB right over a flowering plant hasn't stopped phenotypical stretching, in my experience.

Thanks, Rahz. I grabbed the 1050's for a couple trays of surplus 72V CXB3590 (parallel/series for 35W each).

I was just mentioning what I would do. Go ahead and grow everything out; I've smoked lbs of seeded weed from south of the border.

From the pics, it's gone full male. Myself, I wouldn't bother to hash it. Are there hairs on the other plants? If not, they might have avoided massive seeding.

I'm not understanding why not. I don't see it mentioned here: http://www.ashireporter.org/homeinspection/articles/inspecting-tandem-circuit-breakers/2047

(forum doesn't accept my rotations) One of my bars has three 50W COBs, the center being 2700K instead of 5000K (at 25W). This is the third run from seed and no extra stretching under the warmer spectrum.
