i have seen it done with 250 wall CF bulbs, the buds came out nice but tiny. Why bother with hydro if your not pushing the plants with lots of light? it seems like a simple 3 gallon soil bucket would be simpler? A lot can go wrong with a true hydro setup and its hard to get great flavor unless you really know what your doing. Use some good organic soil and a little organic grow and bloom and your guaranteed great tasking smoke without the risks of crop failure associated with hydro. just my opinion. good luck!!
