highest yield . hands down is the hps. for flower. that's why every pro or commercial grower uses them . leds are for the technology geeks . that spend thousands of dollars to save some money on electric and it will take 15 years to get your money back from the initial investments , cfl or t5 high out put give a ok yield as well. 30 to 50 % less then hps depending on how its set up number of plants so on . led I compare to t5 florescent this is my opinion only. what I have seen in the past , I will choose the t5 over an led any time . if I had to pay for the price cost of led. but I use hps and combination on mh and t5 for veg. to save electric.
What type of lights are best to use for highest yield? In other words so I can grow fewer of them. I've read so much that I'm really confused. I would like to try LEDs the most but have read mixed reviews. Thanks
I'd say before you go into deciding what kind of light to use, first ask yourself what you expect at end result. Shooting for ounces or pounds? How much are you willing to invest? How much space do you have? My best suggestion for a complete new grower is start small, then upgrade as you gain experience. Try T5 with mutiple fixture bulbs. If you're ready for bigger and better then go with Metal Halide for vegetation and High Pressure Sodium for flowering.
