dont expect any bud of your plants lol sorry but its true, having only 1 florescent bulb is not even close to enough light for budding.. dont try LST there under enough stress as it is. and dont mist them when there budding you want it dry,,, Im not sure what lights you should get.. what
chucktownskunk said sounds ok im not sure what CFL bulbs are though,, but yea I would get a couple more florescent fixtures and some warm white bulbs for budding but even thats not enough to get good bud.. for veg get cool white and worm white,, if your gonna keep your plants growing under the same lights there hole life, get three fixtures 2 bulbs per fixture then get 3 worm white also called soft white and three cool white..4 footers thats gonna be like 60$-80$ bucks..I hope you understood all this .
