First time starting a thread so bear with me.

Been in the scene for 15 years and just finally crawling out of the basement.

So, as the title states, Water-cooled cobs.... Lets talk about it. Seen some great info out there and want to help contribute to this movement. I've been working on a new water-cooled fixture and like most could use a little help. I DON'T TAKE KINDLY TO NAME CALLING, ARGUING, OR RACIST COMMENTs... Everything else is fair game. ; )

Where do we start? Of course, build porn... So here is prototype number 1

Ok so that is prototype 1.... Learned some things from that one.

1. Watercooling kicks ass!....Ambient air temp outside the ten was the only limiting factor.
2. 6 cobs created an uneven canopy
3. Dewpoint... Better learn about relative humidity ( and No, thats not the sweat dripping of your sister)
4. Led tech moves rapidly
5.As long as chilled water is near, I'll never pay for cooling again in a sealed room.
6. That I need a custom extrusion because these motherfuckers were heavy! ( 20kls-50lbs) each

Every time I hear someone talking/posting about building a watercooled light, I roll my eyes.

But holy fuck that is awesome! Great work. Is that a dehumidifier hanging in the middle!?

Yes that was a dehumidifier in there. I was growing in a 3x3 square geo pot and the humidity got crazy..

If youre using chilled water are the fans even necessary? Or worse yet possibly counter productive?

In my opinion, ditch the fans on the mounts. They could be used far more efficiently elsewhere in the setup.
