unfortunately that kind of environment pretty common in industry. class I div 1 would be the electronics class you want if your goin into a hexane tank. Div 2 just 1 step below that is like being in the room that the tank is in (assuming good engineering of the room). Im doing a little looking right now for a lower explosive rated one

I'd be real happy with IP67, dunkable, and I'll happily settle for IP65, washable with firehose.

So based on my totally noninclusive search on the interwebs the "HL" in the meanwell name is hazardous location. seems more common with the higher output drivers

Parallel just shares the total amperage among however many cobs you add righ like hlg-600h-42. With 7 Cobs it would run em at 600ma each?
Sorry I thought someone answered this but I think it could drive them at up to 14.3/7 amps or 2.04 amps? It's adjustable though down to 7.1 amps so it'd be about an amp per cob. Please please if anyone sees an issue with this please post.

The 600 refers to watts not amps, caused me a bit of a hangup.

Makes you wonder what made them design a driver to qualify for and get that cert?
I used to work at a one of the now infamous factory that made airbags. The facility I worked at handled a lot of the propellant used in these devices. Most of the rooms were designed to be completely flooded during a catastrophic event.

I imagine it's for instances like that.

Its choppin day 100 days in from breaking ground started photoperiod shift the last week of January so about 70 days in flower (this time I didn't have far to shift was only running 15-15.5 hrs of light, just gimme a break on this one Im comin off a 10 year hiatus). Glads indicate I'm probably a bit early (est. 15% had color, 50% were cloudy, 25% clear, and 10% just developing ball) by maybe a week or so but I'm not too concerned because I have what looks like the same phenome still going so I can compare). These first ones I have are bag seeds possible genetics include Cindy99, Ghost Train, og rugburn, and who knows what els, should not be feminized as dispensary has a good ole' fashioned plants bumpin uglys sex breeding program and this was likely just carelessness on their part, anyone with an eye for phenomes please comment.

The stats - 28in tall, 9g fan leaves, 19g sugar leaves, 191g for the rest. wet
No SCROG, minimal training and coercion, Foxfarm ocean forest, a base 5-5-5 mix, some happy frog conditioner, CANNA flor, bloom, zyme, carbo during bloom, and bio genesis mineral micro nutes.
The goal was to get an oz, I think I'm right there.

My apologies for the crappy pic but I was shakin with excitement and the light in my garage is crap.

Things I'm gonna try next - I want to reduce or remove the perlite and being that Ive been away for 10 years I haven't any knowledge of bias of coco so long as I can keep ph in line Im thinkin this could be a substitute. SCROG, Ive got a topped plant and will be doing 2 more today so theyre ready to rotate in in a couple of weeks. Oh yeah, and the DIY leds.

A special thanks goes to those I've been trolling the last month, I won't say you made it possible but you did make it better by either asking good questions, answering said questions, posting random shit about what they're up to. So in no particular order here is your thanks,
@kmog33 (I still wanna see inside your box!), @Ttysitikk @welight , @bobbyg, @Bachomp , @VegasWinner , @Greengenes707 , @Growmau5 , @Airwalker16 , @selfmedicatedvet (i don't have your screen name right) and others posting about nutrient uptake in his garden post. I'm missing a number of people so don't be buthurt just post here and remind me my memory is in exactly the condition I should expect it to be.

oops the pic...

thanks Kmog not knowing how those wires are connected (thanks for using rated wire) if they're not soldered please consider getting some pushin insulated connectors. Cheap insurance available at home depot.

For those thinking about building your own heatsink I have some free advice for you -
  1. Go buy a heatsink
  2. Refer back to 1
  3. you obviously don't get it so here - go find a friend with a vertical mill, have them flatten your piece of stock, then have them cut the fins in it and viola you have made your own heatsink.

4. Talk to @ttystikk about other options, lol. Fair warning; they get weird, fast.

4? there is no #4........well there is but please not flatstock from the depot more like the Andes mountains, 20 or so hours to get close enough that I don't think I'm gonna catch anything on fire.

I thought I saw something with a ceiling fan, mtb wheel, a 600w or so ....
LMFAO yeah, that was from several years ago, and not one but two thouies! It was a kludge, for sure.

But think creatively about the problem; one is simple mass; if you can thermally bond that chip to something big enough, it would warm up for 12 hours, then just cool off overnight.

There's the guys using CPU coolers, too.
