Yea man I did the same thing and jus jumped into it by buying a ag, and it was the biggest mistake ever. They will grow weed but the amount is not worth the 150 u pay for it. I also suspect the one ur gettin for 150 is the basic and not the deluxe. The basic has a shorter light arm and less light, plus when u get to 12/12 u will have to do it manually or buy a cord which operates the light seperate from the system, cause the timer does not set to 12/12. In a nut shell u would be better off taking your 150 and getting some cfl's and soil, or making a DIY system. All can be done with the 150 u were gone spend on the AG (If using cfl's).
