Not sure what threads you've been reading, but everything I read says the leds give less yield but better thrichome coverage. That is the white cob leds, not the targeted spectrum blurple leds.
Hey man, I've seen people pull off full grows with a basic t5 lighting setup. It's all about maximizing your environment. You could have great lights but if all other factors are off it won't matter.
There are many threads here, the search button is your friend. It's amazing the results people can get with certain set ups. Good luck and keep us updated!
If it makes you feel any better I've changed between hps, mh, led, and t5 a ton. I think it's possible to grow good weed under any of these as long as you know what you got and use it correctly
