Well I'm going to finish this grow up with CFLs. I would like to use the HPS once I get the cabinet built as I'm having real slow and slightly poor results with the CFL. I know I'm going to use mylar or the reflectix..I also have a couple computers laying around so I'll be taking out the fans. For the exhaust I'm really not sure maybe the tubing for dryer venting? Not sure if that would work..
If I end up having to use the CFLs for the next grow I need to figure out a better way to set those up..I live in a small enough town that today I couldn't even find the adapter to go from one light bulb to two!!!! SAD!!
