mate that panel should only be doing a 4x4 spread.you need 2 for that tent.why don't you push it to the one end.then get a cob kit,build a diy light for a 4x4 area.do a comparison grow.then ,when the cobs kick the panels arse,ebay the panel.buy more cobs.lol.I just have the one 1200w cob, its the full spectrum pink kind with ir and uv. I was thinking I could get about 6 or 8 cobs like you have and surround my current cob with them to get a uniform light spread. The 1200 watt(6x200 watt cobs) just barely covers the 4x8 and I dont get the huge colas like I want, thats why I was considering hps.
Whats the difference in the 80 and 90 cri besides the price?ok now i got a better idea of what your trying to do.i think i would suggest you build or buy 2 bars of 4 or 5 and mount them on each end of your tent with your panel in the center.so theres lots of ways to build these but i like the 2 main types of drivers which is 1050ma and 1400 ma.once you get above 1400ma with cree chips your losing some effeciency and as i have said my 35 w cobs do an awesome job on 5 foor tall plants so i dont see a need to go past 50w on these.plus when you drive them soft you have alot less heat coming from them and they should in theory last forever.that cobkits site has some decent prices for diy and so does northerngrowlights.com.personally i like the cree chips with ngl 120mm heatsinks driven with meanwell 1050ma.but you can use this driver to run 4 cree 36v and get 50w each from the cobs and still be safe on the 120mm heatsink for passive cooling.here the driver for that http://www.jameco.com/webapp/wcs/st...reId=10001&catalogId=10001&productId=2189345&
heatsinks here https://cobkits.com/product/120-mm-passive-pin-fin-heatsink/
cree chips here. i picked the 3000k because i like them but i also like the 2700k chips as much lol.
CRI is a measure of how closely the light projects a visible color spectrum nearest the sun. Do colors under this light appear as they would in a well lit outdoor area? The higher the CRI, the broader the spectrum and intensity of the light. The relationship between this rating and its effect on cultivation?... no fucking clue but I figured spend the extra couple bucks a cob and get the 90's. Right?Whats the difference in the 80 and 90 cri besides the price?
more reds color wise and less lumens because of the enhanced spectrum.i like the 80criWhats the difference in the 80 and 90 cri besides the price?
yes and those are not bad price wise if you dont mind active cooling@sixstring
Would two of these one on each end of my tent work, and is this a good deal?
what it be brosef,where in the hells ya been hiding this time lol ? snowing hard here now,bout to get a decent amount maybe 8 or 9 inchesLooking sweet as always Six, hope you're keeping well.

yeah im still pretty close to 1 cob per sq foot.but yes i still have 1 gavita left on that side but its almost not needed now.3 more bars or 12 to 15 cobs will finish out this side of my shop.if i had more time i would be building bars for the other side as well ,but it will happen soon.Six you still think 1 cob per sq ft over your growing area?It seems like you are running less or is their still alot of Hps in there too?
Woah. The $299 includes the CXB3590s? That's a phenomenal price.@sixstring
