  2. even for supplemental thats good

    blue? for horizontal growth(leaf size)

    red? for stem growth (stem size)

    good luck
  3. Thanks since that post ive watched some help videos i understand alot more than before.
  4. Im a fan of 4000k its very white. (4500k i think is like noon time)
    cooler- 5000-6000k are more blue, and ive used them in veg, works good for veg, and 3000k is more warm or as you can see red/orange is better for flower, but ive used 4000k for both with good success.
    Hope this helps
