first, be careful with only one plant, remember that if it turns out male the whole operation was bust. femanized seeds helps prevent that however, sometimes plants can run into problems like disease, parasites, and other misc. problems. I would go with at least two plants.

As far as CO2 goes, a simple box fan will provide plenty of air for your babies, just don't forget to make an intake as well as a vent (only one fan required, it sounds stupid but it has been forgotten before).

For lights look into some CFL's, the spiral fluorescents that fit into a typical socket and you can buy really convenient clip on work light sockets with reflectors. They are probably the best option in fluorescent lighting available for growers. Remember to check the lumens, it should be marked on the box. Sylvania just came out with a new 65 watt CFL, go to Menard's (the best source IMO for CFL's) and check some out. If you Mylar the interior it will distribute the light very effectively.

Good luck, hope I could help. :jointsmile:
