i used cfl's with the clamp fixture. i used 4 23watt (6400k durnig veg then switched to 2700k's for flowering)cfls. i lined my grow space and aluminum foil shiny side out. i'm at week 8 of budding and my plant is 3' tall and got some healthy buds on it. there are better lights out there but...
Buddy gave me some 48" florescent lights 3000k. I was wondering if i could use these vertically during flowering. i know they aren't as good as say 2700k but they are free:clap:.
