well your into a set-up from scratch for 1500 plus the ballast's bulb's pumps fan timers resv. plumbing and thats another 1200 or so. Maybe you just dont have enough money poorman and should save every penny cause once your pulling down the big yields like you would with a HYDROGON you'll look back on these days and laugh seriously though we've been building these things for years and got it dialed anyone who's ever put a 5 inch hole saw through a 6in piece of pipe can tell you what a pain in the ass it is anyway we've come along way since conception and now use a cnc designed jig to perfectly align our eliptical net pot hugging holes. This unit is way worth the investment
