Hydroponics cob light/driver selection ideas

  1. Hello everyone,

    I am a newbie and have a hydroponics setup with vegetables (lettuce, basil) that require 250 -300 umols/sec, DLI requirement around 15-20 mol/day. I have trays that are 80 cms long and 15 cms wide. I am currently using some cheap leds and want to convert to dimmable low wattage cobs which may provide a good light distribution on each tray. I am thinking of having 4 cobs on each of the tray but not sure on what would provide me the PPF I need. Any suggestions?
    Thanks

  2. i am in the same situation with same area, and surely would like to compare notes. i have not yet measured the umol/(m^2*s) yet will do so soon. you are the first person i have seen that references DLI. it is a new science for me.
