Easy too.. clean it up paint the inside to assist reflection replace the tubes with 2 warm whites and 2 cool whites thats important to get the plants to grow proper lower on a chain, to about 1-2 inches of the top leaf adjust daily don't over water its easy on T5/T8's later if you continue remove all lower growth below 12 inches from the top light won't reach that far, take clones of them and improves ventilation keep a small fan there too once done go watch Starsky and Hutch on TV just like we all did in the 1970s ...lol good luck ps once you hit 12x12 remove cool whites and replace with warm whites
