Building and using these lights reckon you guys are the ones to ask these questions
How would you compare HPS to LED watt for watt, would you say 3 watts HPS = 1 watt LED ? or a bit less

How much would you say 480 watts of LED should yield
Reason why am asking my grow area is 8 x 5 with 40 plants was running 2 x 600 HPS an never felt have reached optimum yield
Changed to LED for this grow, nothing special generic Chinese brand 4 x 120 watt panels they stated 2 panels would cover a 5 x 5 area for flowering as a fold open unit. to get a more even par I took them apart an extended them with a couple of pieces of alloy angle.
Totally impressed so far plants are more flexible leaves a nicer green and having real problems this grow getting stretch as i burnt the roots when transplanting which caused them to stunt. It seems the LED is keeping them tight as well with the lights 3 foot of the canopy for 5 weeks there still showing little signs of stretch and its the last week of the flower stretch phase.
Did the same a few grows ago (didn't learn did I) what I found was they shot up later in flower but that was under HPS am wondering will these do the same under LED can only wait c on that result.
