I have a future need to set up a indoor closet garden for medical marijuana and I have the closet (4.5' x 6.0' x 7.0') I bought Marijuana Buds for Less by SeeMoreBuds that describes using the screw-in type
CF bulbs.

In the past I have enjoyed Marine Reef Keeping that result in me having two compact fluorescent fixtures that I think I could re-purpose for some of my lighting needs. Both units are designed to hold two four square pined dual tubes. One unit used 55W tubes and I found out that there are specific lamps (total light after I buy the new agro tubes would give this unit a total light output of 8000 lumens of light at 6,500 kelvin) made for growing plants (it has reef type lamps right now.) The other unit uses two 28W 6700K lamps that are designed for plant growing (marine algea.) Both these units have reflectors built-in. I also have a 175W 4300K Metal Halide bulb, ballast and wiring harness that I could use for the vegetation stage of plant life. I'd need to buy a reflector for the 175W system as it has no reflector.

I also have CO2 tanks with regulators from my home brewing days. I don't want to spend money unnecessarily, if this equipment can serve my new closet. Any thoughts about this are welcome.

Thanks
