Im using Led,300w full spectrum for now, in the future i will get stronger light but also Led.Led is better in much more ways than Hps! With Hps you can possibly get better yield(that is what people saying but im not convinced) but with Leds you dont need ballast, heat is not a problem like with Hps and finally you got much more room.In your place i woud get some Led definetly.Good growing
