So at 32 watts, that would mean your fluorescents are T8's & not T5's. (T8's are standard shop lights). As long as they stay short & 'stumpy', that's fine. CFL side lighting is almost a must though. You do know that you can switch those out for 40 watt tubes? They come in a two pack at walmarts really cheap (T5's are 54 watts). I'm currently vegging under a shop light myself, then they'll go under a 6 tube T5 system with CFL side & under lighting for flower. I grow 'stumpys too, SOG. I find it more cost efficient indoors. Growing the big girls, way too expensive. I save those for outdoors......
