Man I love this forum. Good looking out

Graphite powder might work well for something like this.. .hmmmm8-)

Always lube it up fellas. That goes for most things in life...:hump:

Appreciate that. I was wondering about the max/optimal torque to snug em down...I think you guys have convinced me...I'll give the tap a try. I have a drill press too so shouldn't be to bad

Off topic: Researching seed banks now. So many. And they all have mixed reviews :/ Oh how I miss Marc Emery He personally gave me my first volcano bag at CC headquarters in Vancouver.

If I just drill pilot holes the sheet metal screws will effectively tap themselves. What's the advantage of tapping a fine thread I into the sinks?

@SupraSPL Love this! What a clean looking setup! I already have 110 wired in the room. So I'm thinking maybe run a dedicated 220v for just the lights and use the existing 110v for fans etc. I have attic access in my room (hallelujah! ) so I'm thinking of keeping my exhaust fans in the attic to...

Badass! Thanks for the info :blsmoke:

Update! After doing a lot of heatsink research(see prev. Posts) I had decided on 2 sinks with 5 lights each...until I realized...SHIT I ordered 10 cobs for my bloomroom. With 2 drivers per cob I would be stuck wiring one driver to 2 separate sinks..fuck that. Soooo. I've decided to go with 3...

Good deal. I know I'm a worrier, I just want to make sure I have all bases covered. Thanks for the input guys!

Thanks for the article. :bigjoint: I have a pretty good grasp on it. But what I'm wondering is: 7 drivers x 50a inrush?? I can't imagine they really pull that much. Can anyone who has exp. With the hgt-120 or 185 series chime in here? I haven't seen anyone speak of a dedicated 100-200a breaker...

Ok guys one more question Running the meanwell htg-120-1050.. Differences between input of 110VAC and 220VAC? Aside from amperage draw. I plan on installing a dedicated breaker for the room so that's not a problem. Everything else running will be 110VAC so having to run two separate lines will...

So I have my lighting all worked out see: https://www.rollitup.org/t/first-led-build-cxb3590.868236/ Now on to the room design. I have pretty much set my heart on an aeroflo36. Suggestions for Carbon filters and fans? I have attic access in my room so ideally I would like to have my fan up in...

Easy fellas... @brimck325 most of the prefab led arrays are over priced and underpowered. I've done a lot of research, seems that DiY with cobs is the way to go. Do you have some specs for that light you posted?

So I've decided on my heatsink. 12" x 32" x2 5 cobs per HS Total dissipation 377.7w each Which gives me a static air temp c/w/3" of 35.4C. I expect this number to come to exponentially because I will be actively cooling the sinks, but if the fans die it won't fry my cobs Thank you @REALSTYLES I...

I will do some experimenting with the lenses...maybe just put them on the cobs I mount to the perimeter. I have read good things a bad things about the lenses. I think that they are worth it, just to have the cobs protected from the moisture and dirt of the room, and for ease of cleaning, I can...

Yep. $3 a pop...he even said if that was a bad price we could negotiate... I laughed to myself and gladly gave jerry $3 a piece. Some places in the us are charging upwards of $20 for these things! :o I see Newark has them for 2.68 but jerry threw them in my order so I don't mind paying an extra...

@SupraSPL Forgot to mention that the ideal holders and lenses also came from jerry

@REALSTYLES How many watts per sink? What type of fans? Can you give me Tc, T-heatsink and ambient room temp?

The 90cri is only available in 2 step....seems like the higher step the wider spectrum range....wish we could get 4-step 3000k. Seems like the step supersedes the cri factor...but I'm just guessing here.
