Hey guys/gals... long time reader, first time poster. I've been around the interweb quite a bit trying to figure out if my lighting is adequate for flowering, and I'm coming up a little short.

I started growing bagseed the 1st week of September, no idea what strain or species. Started in the garage with halogen work lights until they started to lose color and thus my new hobby began... reading, learning, patience, etc...

The first thing I did was buy some t12 lights from a big box store and built a fixture and wired them up.. I have since acquired a bunch of stuff from a old pal of mine on loan. I have a 4 bulb, 4 foot t5 setup, which 'the site' says is 20,000 lumens. The t12 setup I made is standing in the closet providing side lighting. I suppose I should hang it horizontal on the wall and maybe it would do some good for more than the closest plant. I also have a smaller 2 foot, 2 bulb t5 setup which I assume my friend used for clones providing side lighting on the other side of the closet.

All of that along with 7 plants is in my 6 foot long, 2 foot deep, 6 foot high mylar encased closet. I could go higher up to 8 feet if I wanted by removing the shelf, we'll see. As awesome as it might be, I don't want to have to stuff the plants in the closet to shut the door, so I'd like to start flowering very very soon. All of my plants have been on 24/0 since they sprouted, all have alternating nodes and all are showing female preflowers. I also just installed a bathroom vent fan in the ceiling and have a small clip fan to provide some circulation.

From what I understand, MJ needs about 2500 lumens per square foot. 6'x2'=12 square feet, so by this rationale I should be providing 30,000 lumens. I'm 10,000 short. My bud also let me borrow a 400 watt HPS set-up. I need a power cord for it, but before I go and redesign my lighting- do you think I need it? Should I just use the 400watt HPS, or use it in addition to everything else?

Thanks in advance.
