  1. Alright so i recently upgraded tent size from a 2x3 to 4x4. I took the light I was using in the 2x3 which is a electric sky 180v3 and I also ordered an optic-led gmax150 to help fill out the tent!.. Now should that be enough light?.. if it helps I’ll be doing 4 7gl. pots with autoflowers

    thanks.
     
  2. 150watt lamp would be enough for a2x2 so you would need two more of those to fully flower a 4x4

    Edit: looking at the Electric sky lamp, they claim it can flower a 2x4 space, so you might be ok with just one more 150w lamp on top of the one you got.
     
  3. So your saying I’ll be fine in addition with the “two” light or I need to purchase 1 more gmax150?
     
  4. I think 1 more gmax at least.
     
  5. Most LED recommendations are for 30 watts per sq ft.
    Autos MIGHT need less, so 25 is probably enough.
    But that still means Needed Power = (16 sq ft)*(25 watts/sq ft) = 400 watts

    You'll have 180 watts + 150 watts = 330 watts, which would be about 20 watts per sq ft if all the space is used.

    Lights are getting very cheap, and many of the cheap white light LEDs on amazon are good values.
