what's the problem? light airy buds? low potenty? most likely your conditions are not right. poor lighting/ventillation, high temps/humidity in flower. harvest too early? i use 400hps for my main flower chamber and get close to a lb ofb really good, top shelf headies but i also have a small 350watt cfl scrog chamber which yeilds about a qp and the buds are almost the same quality as the 400hps grow. my point is you can get good bud with low light as long as you use it correctly. if you use cfls you must either flower only small plants or go scrog so you can keep the lights really close to the canopy (2-4inches).

give more info and maybe i can troubleshoot a little better for you. lights, ventillation, temps, ferts, soil/soilless or hydro, strain, etc. would be some of the info to include.
