secret420 Reviewed by secret420 on . Grow room construction This thread is for anyone who wants to basically design a grow room in 3-D to see how everything will fit and just to play around with. Basically what you do is take the dimensions of the space you are working with and mirror them in a 3d enviroment, you can add almost anything to your room including premade hydro setups, plant potters, any size flourescents, even an airconditioner and flexible hoses. this program rocks!!! The program is called google sketchup pro. it a 500 dollar program but Rating: 5
