Have you done par measurements?

Hey naiveCon! Tell us about your grow!

I'm 60% water. Not a very scientific reasoning for crapping on something. The bacteria culture may require it.

Ohhh, what are those? What kinda yield are you getting per watt?

This is weird, because I've seen growers with zero stake in selling things have a substantial grow difference in tests with mammoth P. But I know Dude Grows is pretty damn reputable. Watching!

Heh, you might've noted my earlier comment about "2am and stupidness". I measured everything with a micrometer, and it looks like the driver is operating outside the norms. 202V and 1.35-1.4mA. Actually too hot for the driver rating.I'm going to see about returning it and getting a new one.

Series, cobs needing 36 forward volts at 1050mA. I was just tired/frustrated and saying the wrong things. Went over the wiring with a fine toothed comb and used the driver on a different set of cobs just in case. Same problem, so driver specific. Checked the wiring to the power cable as well...

I'm running 18 gauge solid. The driver acting weird has a 7' line from the lights to the driver board. All other drivers are working fine, including the ones with a 10' line (2.23% loss, if I'm right about 36v at 6.3A), though their cases are too hot to rest your hand on. (Really need to get a...

Wow, everyone is building tonight. I hung up the panda film and I hung and wired up my COB rig, with my drivers mounted on a wall outside the tent. One half works fine, but the other... womp womp. Lights go for 5 minutes. Then they turn off. After I unplug it, it stays off for 2 second and...

Posts like this save me from 80 hours of research with no real outcome because conflicting info/no best practice/etc. Thank you Worchester!

COB lighting is a type of LED. (Circuit On Board) Currently the most common do it yourself LED lighting for us growers that are good with a small amount of electronics/framing work. Bosgrower and I just built our own lights for a fraction of what you would see online. We (I'm volunteering BosG)...

Yeah, those pin heatsinks are boss. I saw a comparison between that and the extruded aluminium and the difference is staggering.

They haven't been back at the site went down.

Thank you for paying attention. Anything else we should know on that front? (Also, would you think a building with three separate apartments and a shared basement count as "3 households"?)

Do we want to try and mobilize the troops by calling our state Congress reps?

I was going to play with that and the lighting specific CAD program (luxeon?) But I just haven't had the time to learn how to use them. I'm super interested in seeing what you do with them!

Ttystikks, can you share with us your room set up? Someone mentioned you/it on Crazy Dago's Roundtable last night and now I'm curious. (pointing me to a thread describing it is also fine) Unrelated, gods I am enjoying this weather! Also, I don't know if anyone here knows, but setting up...

How is the light distributed from most COBs? Is it even across the 120 degrees? I've been trying to figure out how to DIY my own COB set up and I'm running into this stumbling block as to where to place them and if I should bother with reflectors/lenses in a closed room.

My friend was JUST talking to me about that. Are you just mixing them with water and saving shit tons of money?

Ugh, I want to look at the data but no pictures! ::cries:: ::varuca salt::
