if money means nothing to you then just keep using HPS. you'll get the same results your electric bill will just be 30% higher every month. If you can control you temps you can get the same LED density with HPS, theres really nothing special about either light that makes a huge difference in qualityHello Mr. CobKits! Pleasure to have you in the debate. I think you’re just the person I was waiting for to drop in and share his knowledge. I have 2 side by side hyper dialed in 8’ x 12’ rooms with 18-20 gallon Rubbermaid Brute DWC bins bubbling away. 6-600 watt hps in each.
8.5 months of the year I can dial in any temp. How would you light up both rooms so that I can first show the results with HPS lights (6 hortilux super hps 600 with adjusta wing avengers retracted to the 3rd adjustment hole) and than the superior results of what could be done with 2 side by side LED rooms. How would you light an 8’ x 12’ footprint to go head-to-head with 3600 watts of HPS ? I will buy your wares in Sep 2018 if you can suggest an LED lighting strategy. Keep in mind that money means nothing to me.
but back to yor question about a side by side, i would make sure they ae the same area, same nutes, same humidity. LED side should be 10deg F warmer to compensate for the lack of IR in the LED spectrum (or you can think about it as the gross amount of extra IR in the HID spectrum). in any case you probably need a dehumidifier to maintain the same humidity on each side. to the best of your ability try to keep root temps similar as well
if your 3600W of HPS is single ended you can probably match it with 2000-2300W of LED. If your HPS are DE, probably 2500-2900 W of LED. Depends on the efficiency of the LED rig you build. since you say money is no object we would probably want to spend a little more upfront to un a higher number of diodes softer for better efficiency (the cost of which would be offset in electricity over the life of the fixture)
