hmm, read this thread from beginning to end... all these "experts" weighing in with their personal opinions, lots of talk of spectrum intensity, lumens/w.... high and low outputs in certain light ranges.
tf you all on? has everyone in this thread had nothing but smoke blown up their ass to help confirm their personal beliefs (most of which are total fucking bs btw...) in terms of legitimate output, quality of flower, potency and yield. fact of the matter is, there are only 2 values that should be considered. lumens/sqft, and CRI... its amazing how a thread about nothing but lighting... 5 pages in, and not one person has touched on the subject of CRI ? tf is wrong with all of you. simply put, even though its old tech, it has Not been surpassed by any other style of lighting. Ceramic metal halide is hands down without question, the absolute best. far from cost effective though, LED, HPS, MH, Induction... all fall short to CMH. CMH has a CRI (with quality bulb) of ~95%+. 2nd closest will be induction, followed by HPS, and then LED and finally MH. argue, bicker, bitch, complain, attack me personally. none of this will change the facts. when it comes to best of the best and concentration on quality of product, CMH simply cannot be beat. not going to argue, discuss, nor respond... believe differently and want to dispute? theres this amazing thing referred to as search engines... do some research and learn something. as to the rest of you claiming this or this is the best.... you have no idea what youre talking about. and function on purely on ego. Prove me wrong. With verifiable facts. until then.... CMH is the goto in terms of yield and quality. HPS is best in terms of value /$.... LED isnt far behind hps but has a very high initial buy in price. Induction is on par but wildly over priced... MH will beat out HPS on potency but never match in terms of yield. Realitys a bitch.
