if you dont understand the tech and just want to get growing this would be a good investment http://timbergrowlights.com/model-2ts/ once you use it and understand the tech and want to expand and feel like taking a stab at building your own theres about $200-250 in parts in there

no beef, we all knew that again thats just a guess. if you tried 330W of mars next to 330W of your light results might be a lot more similar than you expect when it was understood that they are more expensive than, and less efficient than the HPS lights they are designed to replace. plenty of...

again thats just a guess. and your bar is mars and kind which arent considered to be in the realm of acceptability these days im sure it works and grows great bud but again the attributes you are giving it really have no basis. pull a mars apart and put bigger fans in it and you might see the...

there are many ways to rate LEDs. for our purposes these are the important ones -color temperature -CRI -efficacy in lumens/watt or umol/J

"Come by my place I show you all the proof you need." a light growing healthy plants is no measure of efficacy whatsoever not trying to be argumentative, what i speak is not my opinion and i am not talking down to you... it is the commonly accepted knowledge by which lights are measured in...

im not calling you a liar, just uninformed. What i say isnt "gospel" but it is accepted as fact if there was a light that put out zero heat on the market every single other light manufacturer on the market would be out of business the top top lights on the market are pushing 60% system...

thats impossible all current LEDs put out 40-60% of input energy directly as heat

4 citizen 1212s at 35W would work well in that space, efficient and economical. you can buy something like that from timber of build it from parts for less. depends on your skills. end result is the same

and there are a lot better options than this light for that

most of the 14-15W bulbs are 1600-1700 lms with the covers on prob 1700-1900 without the difffusers

the roxy was something else. one of the best shows ive ever seen out of hundreds and hundreds

most people use 3000k and 3500k

fuckin' clownshow for sure

yeah theyre all the same. jam a screwdriver straight thru that plastic globe and out the otherside and pop it off. the leds are on a flat plate down in the base

cost per watt for drivers doesnt vary that much by size. little bit but not night and day the larger drivers are a few % more efficient (say 96% for an hlg600 vs 93.5% for an hlg185)

sure but the "100W equivalent" 14-15W/600-1700 lumens are 5 bucks a piece and more efficient per watt. make sure to pop the covers off

they make all kinds of drivers in all sizes, you could have one driver running one fixture, multiple drivers running one fixture, or one driver running multiple fixtures

wasnt doubting you per se... their lack of info speaks for itself

no reason they cant any different than any other light. if youve got shading you vot shading no light is boing to penetrate through solid leaf to foliage below. more points of light will help in any case have you considered strips for side or intra-canopy lighting? yes i do run the site, you...

i didnt see that on their site
