You could cobble a cheap fixture like this together,
OR use the 24" T8’s you have. Just about anything is fine for lighting clones. The T8’s would need to be closer to your clones, with the 9w LED bulbs you can have them 12-18" away.
CFL doesn’t give concentrated light, I’d rather see t8’s in use over CFL.
Those screw in LED bulbs are cheap and easy to modify for growing.
My seedlings seem quite happy under the fixture I pictured above.
Welcome back/Welcome to the new OG, happy growing, and post updates when you figure out what you wanna use!
