Need lighting help for my closet.

Hey people.

NooB here, currently on my first grow, have three white widow plants in my 6 foot wide, by 6 foot tall (to the rack), by 2 and a half feet deep closet. I did a TON of homework before I started my grow, and things are going well except....(duh) my lighting.

Currently I have two shoplight fixtures with 4 Daylight bulbs pushing 3050 lumens per bulb... things were going absolutely GREAT until the plants started getting some height on them, then I quickly found that this is not enough. I have 4 lamps with daylight bulbs at about 2000 lumens per bulb, BUT they are on the third plant alone, because I used MG soil and burnt it up, transplanted to Ace Hardware Brand Organic and it's recovering, but WAY smaller than the other two.

OK, on to my situation. I really wanted to go HPS, but I cannot vent because I'm renting this home, and I do not want to cut a whole in the closet that I will eventually have to pay for. So it'll HAVE to be flo grow. Side lighting is an option, but I don't know how to hang or mount the lights.

Could someone give me some recomendations on a CFL or Tube setup that would work well for me? I like those 200W CFL's but they are over $100 a bulb!!!!

Also, does anyone know where to get a multi socket fixture either medium screw size or mogul CFL?

I included a pic, but it's fuzzy cause it's from my phone.

Any and all help is GREATLY appreciated.

Hey, just wanted to ask because I forgot to, how many lumens overall would be optimal for a flo grow....4 WW LST spiral stylie, grow space is 6 feet high, 6 feet wide, 2.5 feet deep.

Thanks for any help.

Ok, found an 8 tube T5 fixture, 40,000 lumens comes w/ 16 bulbs. That would make 52,000 total lumens from my other lights as well, is 52,000 enough to grow 4 WW LST?

I'm planning on just 2 for flowering.
