Is this 4 x 150W HPS for a total of 600W? Hope ya have good ventilation! I'm guessing you meant "for", and it's a single 150W HPS

Tough call. I'd use the HPS with your current CFLs as sidelights, giving you about 225W of mixed lighting. Your flowering box is the same size as the inside of my closet (I'm using 300W of CFL): you should be able to do 2 or 3 plants in that size easilly with those lights, depending on strain, and assuming all other needs are met.

As far as vegging on the shelf below, there's no easy way to lightproof between shelves in a closet or wardrobe. You're prolly better off with a seperate veg area; during bud cycle absolute dark is important.
Volker Reviewed by Volker on . Lighting Question, is it worth it? Ok I found a website that sells a sun system 4 150 watt HPS light for like $100 brand new with a 5 year warranty and as of now Im growing with three 27 watt CFL (105 watt output) but for one plant. My environment for flowering is about 3ft wide x 1.5ft deep x 3 ft tall. I currently am pulling decent yield, but I wanted to expand to growing 2 plants at once. Will this single HPS lamp be a good buy and will I get better yields over the two plants with this light as opposed to the one with the Rating: 5
