Dont vent the light like crazy as 75% of the energy a bulb uses is to get up to temp to run. For CO2 consider yeast water and sugar and shake it once a day. It works great. In an apartment I used to have I build a cabinet out of a dresser. I took out the drawers and smashed off the backs then glued them back on. the whole front lifted off. I had two plants in bud when the owner sold the house and no one was the wiser. Any way good luck and have fun
One love
