There was a post from last week that got lost that I was interested in. Basically talking about the efficiency of white LEDs and producing lumens compared to red/blue/other color LEDs. While I lean towards PAR over lumens I did find a grow using white LEDS and was surprised with the veg results. I would like to continue the discussion here. Hopefully RIU can keep our posts around. I lost a full journal.
