Okay, so I'm no noob, either in a growroom or here at RIU. I've spent the last couple of years developing a vertical growing system using 2 HPS thouies as lighting for the inside of a cylinder that's just over six feet tall by five feet in diameter. That's right at one hundred square feet... and yes, it produces.
I want to light the same cylinder I just described above with LED, and it needs to be better than merely 'HPS equivalent'. I'm after current state of the art... and just to throw a monkey wrench in for fun, fully wettable lighting would be ideal, though I suppose not required.
Anyone who says money is no object will soon be parted from his money, so I'm also after an education about what the options are, what they cost- and what I get for the cost.
Who's got some ideas?
