you can overdrive the 4 foot t8 bulbs by as much as 4x by using a 4 bulb ballast driving 1 bulb. I have a few 2x overdriven fixtures and they are a lot brighter than stock. they are pretty much as bright as a t5.
I am sure you could do a sog style grow for maximum yield.

Fluoro Tubes vs CFLs Hey all, Im new here, however i was a faithful member of OG may it rest in peace :( Im about to start my second grow and wanted to gain some more info so i can improve SIGNIFICANTLY from my first grow. My question is what is better the basic fluoro tubes or cfls? I do realize that most people feel HID is THE way to go, however i have found it quite difficult to find appropriate HID for growing. Also the price to buy and run fluoros is much less than HIDs. Sure the plants may yeild Rating: 5
