Are the Z2 3000k cobs still good? I can't find any z4 or ABs anywhere, anyone know where else I could get two?

Do you think this would work? http://m.ebay.com/itm/310948865469?cmd=VIDESC

Sounds about right to me but I'm not 100% sure. Pretty awesome results for only one cob.

Sounds awesome dude I might get that same set and put it together too!! Stoked to get it going. You liking it so far? Can you power two cobs with that driver or just onee

Yeah that's what I was thinking too at a lower mA till I get some builds under my belt. What would be a good one for a 1 to 1

Yeah I was reading some of supars stuff on driving them less. Thanks a lot for the help man much appreciated. One last question do you think it's more effective to run one big heat sink and one big fan or small heat sinks and fans for every cob?

That's what I'm trying to figure out, for my area haha. Guess I'll just have to make a few and start from there. I don't want to work with to high of voltage right now since I've never made one before but it would be cool to get two cobs to one driver and drive them not to hard but enough and...

How efficient is that driver you think, will it power two cobs you think. Sorry I'm new to this and want to make some too.

which model would you recommend for a 4'x2'x5' area, Cuz I know there's a few different ones, I'd like to have good yields but still be pretty efficient.

What drivers would you recommend tho for my set up?, cuz this spring and summer I can use them, along with growing outside.

It's been pretty cold up here in Alaska right now 2 degrees F and my tent is in my garage so that's why I can't go 100% led Cuz it's like 50-58 in my garage with me lights on and it's around 70-75 with lights on with my exhaust fan going 25%. I'd just like to go cobs Cuz I know they use hardly...

I'm not in a big hurry to build this and it's still a little cold for me to have all LEDs right now so that why I'm still using a HPS to create heat, but I guess I could always get a small heater. if I buy the parts for these over time it's not a big deal in how much it costs. Just don't want to...

Yeah I've read thru that a few times, I'll read thru it some more.

Been reading lots and lots of threads on the Cob DIY it seems pretty easy enough to build. I'm just confused on what drivers to get for them, and how many cobs I should get for my tent , 4x2x5. Usually only grow 3 plants 4 maybe max. So what drivers would work best for these and most efficient...

How long did it take to get yours?

I just ordered some seeds from provision and there seeds so I hope I get the promo for being. RIU member. Stoked to try em out, and to do this comp. Props again FC!!

Oh good call I'll start working on that today and finally decide what fem seeds to germ.

Yeah I know just trying to figure out how contain them Cuz I'll need some sort of drain hole on it, I'd think. But maybe I'm wrong.

I've never done a comp like this before or finished a grow in party cup are you guys putting screens on your drain holes to contain the roots? Cuz I'd think trimming the roots would stunt growth wouldn't it, or am I wrong?

Hope your buddy is doin well man!
