For the stiff necks out there, let me stress that mix cfl lighting is superior to just switching from blue to red, I have had some very successful grows under this system, the only problem is... the amount of work needed in adjusting and making sure you are supplying enough lights, we have a CFL pro on the web site who has grown a pound of Jane using a bubbleponics and about a thoundsand watts of cfls, I don't know if he used mixed lighting but he is the only one I can call a true master at this cfl game. So unless you have had very satisfying grows with CFLs, STOP being snobs, I breath this shit, and have paid bills with this shit.
