  1. how many lumens do i need to grow a healthy plant? just one would 3400 lumens do for a lil while?
  2. 2000-3000 per sq ft.
  3. thanks im doing flouros
  4. I agree, 3000 per sq ft,

    Imho, you need about 6000 total full spectrum flouros to harvest 1 healthy plant.

    I used flouros for 3 years.
