Just bought a 150 watt sun system,for my 3'x4' veggie room (old tiled shower in basement)hps 150 watt bulb=16,000 lumens.The reason I picked this lite is because of space.Will this lite be enough good growth? Should I add another one.Have a bigger room,4x7x7,for flower.This is my first lite,hav'nt opened it yet.Just got mylar up and doors on. All new ball game (inside)for me,but am an avid out gardener.Am 64 yrs young,so don't believe that can't teach an old dog new tricks story thanks tri-panic
