sounds good I know I will need some hps lights soon, ya I am hopeing they don't die I would have liked to try this with homegrown seeds then pull out the better seeds when I had some better know how on growing but I will just keep pluging alone and hope for the best.As for how old, the bigger one must be about two months and the smaller, one or one in a half I never wrote on the calander when i started them. My bad.
