Day oñe for purple chem. Grew one last year. You could smell it four blocks away even with a new filter.
Ha yea , us old school dudes , I got the same one with the same wires hanging out the top , was the best option at the time , I remember being so happy when I found it at h depot , it was like the future of lighting back then .....Mogul base 65w cfl bought at home depot 20+ years ago.
