this is why i run my cxa's at higher amps. at the time it cost less to make more umol with more amps vs more chips at less amps. and in total id save about 5 bucks a year in power to run things at max efficiency.. i mean if your power costs a shit ton where you live. than i guess a 2 to 5%...

i hope to god an iceland happens.. but i hope that for here too.. and free heath care.. its rad.. your country should try it.. but it would mean disbanding your private heath bullshit and having everything govt run and have things price capped..maybe you guys should just vote for us to be your...

according this and many other polls trump should win..but i know for a fact Hillery will be the next puppet

I have a 2x4 tent and was wondering how many lumens I should have of light in there?. I already have 2 3070's running about 100w's each and putting out roughly 20,000L total. Im thinking of doubling that. but with those t5 led tubes. there cheap and they seem to last a while. would 40,000Lm's...

ohh i use the cold air for my tent in the winter.. and wind turbines...yeah maybe once i get a few acres.

he is right http://astro.unl.edu/classaction/animations/coordsmotion/daylighthoursexplorer.html that being said. if i had been growing a photo strain out here it would not have started flowering yet or just have pre flowers. frost has already happened as of sept 12 so id be screwed. though the...

where in the shit did you get that strain?.. ive been looking hard..and no i don't live in the states so clones probably wouldn't make the border.. starting to think maybe i should save up for another cob.. or just go against all advice say fuck it and get the cheap asian shit panel. i have...

even to supplement the same wattage cxas? i already own 2 cxa3070's and they run at 100w's each.. just want to see if i get better results adding blurple. or would it be better to just add more white? maybe something like 6000K to compliment my 3000K chips?.. also does someone make a Blurple...

I happen to live only a few hours drive from Alaska. of course the growing season is short. but what most of you southern folk forget about, is our daylight cycle. you see, from about late may, after the last snow fall, usually may long weekend, the sun begins to hang in the sky and not come...

im looking for a blurple panel to add to my cree cxa set up. wanna give the plants more a "full" spectrum.. i dont wanna go over 200 bucks and i want something at least half decently made.. hopefully 10,000ish lumens. yes i know build it yourself.. been there done that have my cxa lights and...

im gonna get pretty much the same light to go along side my 2 Cxa3070s they run at 100W's each http://www.ebay.ca/itm/1200W-Full-Spectrum-COB-LED-Grow-Light-For-Hydroponic-Gardening-Greenhouse-/302035843800?hash=item4652bd3ad8:g:8bYAAOSw0UdXqC-4

its a cheap asian one 37v 2.23 amps and 88% eff.. its been a while since ive looked at my set up. im about to do another grow soon. but i wanna add more light to it..

ok so what would be the best chip IE most lumens per watt i could put on a driver running 40V 2.5 amps?

If i have a led light setup using a cxa 3070 chip. can i switch it out for a 3590 or vero 29 or a clu058? with out changing drivers?

just treat a COB like a cpu.. i love using cpu coolers for my chips. maybe someone might even think of putting one onto a water block

anyone ever try to grow with a cheap LED flood light? like one of these http://www.ebay.ca/itm/LED-Outdoor-Flood-Light-Industrial-Lamp-Spotlight-10W-50W-100W-150W-200W-400W-US-/182005511721?var=&hash=item2a605fb629:m:mCw90hrWULKygBXo02CtoBw I own a cree cxa set up.. running at 210Ws and...

besides if the cheap asian chips blow on the thing could I not just install a cree version of the same thing.. even if i had to switch drivers out?

what cheap blurple style light can i get for around 200 bucks? .. needs to be 100 plus actual watts though..ive been looking around.. and yes i know i could build my own panel but im way to lazy to try to find all the materials to build it. Id have to order everything online.. i cant even buy...
