$2700 for a setup with 1 400w light?!?! You could build the same setup for less than $1000. If you like DIY projects, than I would say DIY , for me building my cabinet was half the fun.
For $2700 I could rent an apartment on the east side, and do a complete 400W grow from beginning to end, and that includes three months rent! I bet I could even up it to TWO 400W lights, and do it in hydro.
