  1. so i have 120w cfls 6500k and a 150 w hps should i use both for veggin?
     
  2. YES! You want not only blue spectrum but the added lumens that the HPS gives out. Those additional lumens work wonders!
     
  3. So long as it doesn't cause a heat problem, more light is always a good thing.

    With CFLs make sure you are looking at actual wattage and not equivalent wattage.
     
  4. yes and make sure you have good ventilation.
    and fans :p
    having a thermometer is so handy
     
  5. One more quick thing is be sure to use the SIDES of the CFL's.... they give off more light on the sides than the tops.
     
  6. the hps light i have deff isnt giving off any blue spectrum, its more of an orange...is that not used for veggin?
     
  7. yeah. it's orange. some folks use HPS all the way thru grow. but you shouldn't use 6500 thru flower fyi.
     
  8. so it is ok to vegg with this red/orange spectrum hps? and 3500k for flower correct?
     
  9. ubet. that's the ticket.;)
