1500 lumens

  1. will 1500 lumens work to grow a full healthy plant or do i need more also will 750 lumens be alright for a small plant until it buds or a couple of day later?
  2. I really think if you want a viable, smokeable plant you need about 6000 lumens, what do I base that on? Its the amount of light put out by a $9 wal-mart 4' 2 bulb flouro. You dont have to use 4' flouros but I would shoot for 3000 lumens per sq ft of floor space.
  3. I had 1100 lumens curley floro bulb on one plant directed at the top. And its been growing good. If you have 1500 lumens in a bulb (not a tube) and have the light directed with a reflector you should be good for veging but i would get another 2 for flowering and put them triangulated around the plant at mid level with reflectors behind them.
