a 400 would be about ideal for your 2 by 3 area while your 250 will work it is a little underpowered for the space of 6 sq ft puts you at 41 watts per sq ft.
bejay Reviewed by bejay on . too much light? i have a grow area 6'sq which requires about 15,000 lm of light, if i bought a 150watt HPS light that would produce 16,000 lm which seems enough but i was told the more light you have the better the bud so if i bought a 250 watt producing 28,000 lm would this be too much light. what would happen if i flooded my plants with light? thanx 4 the help.
