Ya dontwaste your time with a 150....You need light..A 400 watt hps/M H would deffently be thesmallest id go personally.You can get a complete light system as you described in a 400 watt on amazon for about $160.00
Trust me you need more light.Ive got 6 plants and using a 1000 & 400 watt HPS and great buds!
