Hello all. Currently in the design phase of my closet grow, and I have been doing my research regarding lights. My space is 4’10 x 3’4 x 7’10, or ~16 square feet, and I intend to scrog and use every inch of space available.
I know that HPS is the “industry standard”, and that 1000 watts are recommended per 16 square feet of canopy. That equates to ~1000+ ppfd, typically higher if it’s mounted close and air-cooled. However, I can’t justify using 1950s technology in 2018 because it’s inefficient, hot, and ultimately outmatched by new white phosphor LEDs in terms of spectrum, light distribution, and photon output.
So here’s the thing: I want to create an LED array that will break 1100 ppfd. My research first led me to COBs, then Quantum Boards, and now I’m looking at SolStrips to use as my light engines.
I also want to create a uniform light distribution, so I’m looking at 9-12 2-light SolStrip bars or 6-8 Quantum Boards and running them soft for efficiency and heat management. Ideally the array would stretch from edge to edge, without hotspots or gaps.
Now the question: is this too much light, or is this a reasonable build for a 1000W HPS replacement?
