Comment to 'Viparspectra P2000 and distance between LED and plants Tops'
  • Look at the ppfd map for the light, I wouldnt accept any thing less than 500 ppfd in the corners of the tent and an old school rule of thumb was 35 watts per Sq Ft minimum. Personally I think 40 watts is closer to the min and 200w/6sqft 33w per sq. ft so that light would be under powered fir me. Search the old messages, RbtAsq has a good light with great PPFD coverage for a 2 X 4 area but I am not sure if that would over kill for a 2 X 3 area.
