Lighting Question and LST ?s

Is 8,900 lumens, in a 2' x 2' x 2' space this is a combined lumens from HPS and CFLs above 2 plants, and could i grow 3 maybe 4 plants under this amount of lighting if i add more CFLs, top them so they grow wide instead of tall, and use either Low Stress Training or SuperCropping Methods?

You can grow how many you want, but the result may be awfull. You should tell the wattage of the bulbs, but a 250w HPS will do fine for 2, lst them and it will probably do for 3, maybe 4..... And alot of CFL surrounding them as well.
