Thanks for the link, I didn't know what ones had been tested. I just order 2 of them.

It don't matter what kind of heater they are all designed to create heat and most are very efficient at that. I'm not suggesting anyone put one in a tent or grow especially not an oil/fire based heater, that just sounds dangerous. I would insulate really well first off then reduce exhaust or...

Space heaters are designed to produce heat, the are very efficient at that. ;)

The one to ask about that would be @Eraserhead

for $38USD shipped thats not even a bad price even if its only a Z2, no import fees from china.

@iPot , the graph Pos posted the first page of this thread shows it. If the CXA has a Tc of 55C and you use a Constant Current driver that outputs 1.4A the CXA will draw 37V at 700mA the CXA will draw about 34.5V and at 2.8A just about 41 volts. while I was typing he beat me too it but you...

Looks to be about a 3% difference in efficiency. #'s courtesy of supraspl

I get $3 12' 300V 16/2 extension cords from the dollar store like this and just cut the ends off. Its the cheapest source of wire I could find locally, works out to $0.25 a foot. On the label it says its rated for 13A/125V 1625W max. The electrical supply store near me wanted close to double the...

You say you don't get root rot problems, how do you keep the water cool in the warm mini fridge?

I couldn't find a way to chill single a waterfarm and 1 gallon bucket DWC containers. Its not cost effective for a chiller and ice bottles don't really fit in such small containers. Everything would be going great with beautiful white roots and within 2-3 days you could see them go through brown...

I have been trying DWC and waterfarm type styles for the last 2 years with nothing but failure, just root rot problems every time. It doesn't matter how much scrubbing/bleaching I do, I tried a bunch of crap I can't keep the water temps down and ph stable. I have tried a few things and no matter...

^^^^^ Looks good man, I never thought that would work but you're definitely proving otherwise.

@FrozenChozen thats a nice looking plant, I forgot you were doing DWC. Can we get a root check? ;-)

@SomeGuy, Man does that look GREAT you could use that canopy as a table its so flat! I would love to see some PAR #'s from your setup as I'm sure at that distance and with that much power its gotta be damn bright in there. Do you think that level of light saturation which must be far beyond the...

Link to cheapo driver please? if you're talking about the perfectdeal_us (JLX-LED) ones, they have been sold out for a while now and only available if you buy it with the a crappy COB which makes the drivers not so cheap anymore plus there is a 15$ import free to canada. Is there a different one...

I don't know how to explain it that well, this is a excerpt from http://forums.anandtech.com/showthread.php?t=157631 Its not a big deal for just a few drivers but the more you have the worse it becomes costing you more in electricity. Really though for the individual its not a big deal, its...

The 48v is the only option in the lpc-60-1050 and the CXA will run around 36-37v at that current, which is about 88% max load. The further away from the 48v max, the less efficient the driver becomes. Since there is no efficiency chart in the LPC spec sheet I couldn't tell you how far below the...

I like the idea of 730nm not being on a separate timer and I think the IG pontoon has the best idea with the battery powered initiator at lights out. If I knew how to build a circuit to charge the battery during lights on and then run off the battery during lights out I would definitely build...

I forgot to mention that the data logger has a RTC circuit built in so multiple timers is not a problem I think (I really dont know), its all done with 24hr time not millis. With a 4 relay module I can turn LED and fan drivers on and off, and plan to control them all through PWM...

I have arduino control multi-channel lighting on/off timer right now in a test (party cup) cab. Eventually I will be trying to fade them on/off with corresponding PWM fan speed control. I also have the data logging shield for temperature and humidity, eventually it will be ethernet and I will be...
