is it 3' total. if it is the case you have to remember you have hanging lights, etc... if you are looking for bushes, you gota top them. everyone is different based on their needs, but for sure i would top. stay away from lowrider. smoke is horrible. if you take the time and read about topping here you can grow dank the same size as lowrider. the only thing lowrider has going for it is the autoflowering, but hell, a light timer can do that also. PEACE!
