Just ordered a phresh 750 and a hyperfan 710. I'll let you know how it works out. After reading lots of reviews (lots and lots) it was between this and can fan setup. And no! Carbon is not carbon. You need virgin activated, beware eBay imposters!!

Amazing work. Huge buds! Would love to hear the final numbers after you're all done curing. Subbed!

I talked to AN and also current culture. The DI water is safe, you can use any water for AN as long as its = or > 150ppm. Current culture told be because of my low temps and high LPM o2 that I will be running the AN at 1/6-1/4 strength. Woohoo! Money saver

The efficiency decreases above 25C. Hence less lumens or PAR. @SupraSPL has done extensive research and his graphs are available under this fourm

Awesomeness! Nice and clean. Looks great!

You need ac for sure. Not sure what fans you are using but pulling air is much more efficient thank pushing

Still trying to wrap my mind around this setup. A more lowpro approach might be to run the elbows from hole to hole (almost like and electrical setup in series) if you can find an efficient way to cool all that water (chiller) or maybe a small car radiator. I can see this being a good design...

Check out Craig's list. I found a 1/4 hp chiller for 150$. Once you get your cooling down. Maybe just run it through a chiller. Water+high voltage DC makes me nervous:shock:

Should be able to highlight copy, paste. Post a link to your other thread

What kind of LEDs?

I'm sure everyone would be interested in seeing your plans. I know I would. Can you post some pics?

From what I've read the liquid cooled setups aren't really worth the money. You can keep the cobs cool enough with a heat sink and fan. However there are several threads about liquid cooling, I haven't seen any badass, successful setups as of yet. Below 25C there really is no exponential gain in...

I just bought the nocturna 140mm and I can tell you they are worth every penny

To each his own. But it could.of been used for something. Donate it to a medicinal patient, smashing electronics just makes me cringe. Something of value can always be harvested, put in the misc box and used at a later time. And you are correct, hobby not profession

[/IMG] I used the existing transformer and bridge rectifier to wire the laptop fan/sinks. Plenty of power. Wired to the existing switches and made holes for pots through the hood. Works perfect. Runs cooler. Brighter. I was pretty proud of myself. Plus I got myself some experience before...

I won't even measure the Crees. Before I started on the grow setup. I ordered Chinese LEDs and drives on eBay for 10$ just to mess with them and figure it all out. I ended up retrofitting my nanocube fish tank using old laptop heatsinks and buck dimmers. Tank looks great and only cost me 40$...

I think @bicit hit the nail on the head. The meter need to be in series instead of fighting the led for current in parallel. Makes sense. Dumb move on my part. Good thing I originally experimented on my crappy Chinese practice LEDs. I wasn't going to make the same mistake twice with my precious...

Yep I was doing it all wrong. Thanks for the education!

I'm.not racist by any means. But that man is ignorant. He probably could of fixed it or at least harvested parts. Why would you do this? It's not a bad light. Maybe better for veg and not bloom. People like that have no business in our profession. Black or white it doesn't matter. Just plain...

Use the heat wattage dissapated. So it's total watts diss divided by your efficiency. Check @SupraSPL charts. He laid all the numbers out for us on a spreadsheet
