First grow here and things are looking pretty good. Two plants in coco/perlite using FF hydro food. Plants are 12 and 14 inches now (pretty bushy -- from seed -- feminized white rhino; seeds from Herbie's). FIM'd 9 days ago and I'm still not sure I did that right, but everything still looks pretty healthy.

Lighting is two T5 fluorescent light panels; each has four 6500K HO bulbs (2 ft, not 4 ft). This is in a 3x3x6' grow tent, so not much room.

I want to switch the light cycle to 12/12 when the plants hit 18 inches or so, and that will be pretty soon, the way things are going.

Question... Should I also switch the lights to 3500K tubes at the same time? Howzzat work? I've ordered enough 3500K tubes to change everything out and the plan is to swap the tubes at the same time I drop the timer to 12 hours. Does this seem right?
