Nice set-up. Ladies looking good, too.

Just a couple of things from your first post...

Curious why didn't you just paint the inside white, since you had the paintbrush out already? The ease of use with painting inside with an enamel flat-white paint, in my opinion, far outweighs the 200 or so lumens (random number chosen, but the jest is obvious) gained by the reflectivity of the mylar-type stuff. Plus, the flat white paint is extremely reflective, cleanable, won't come un-taped and land on the lights or plants, won't rip or tear, and is completely silent.

Is there adequate airflow giving resistance to the plants? Venting cool air in, and heat out is good, but actual airflow increases the strength of stems, and assures no dead-spots. (stagnant air and heat)

Personally, I have two timers. One for the veg room, (18/6) One for my flower room. (12/12) My ladies go from one to the other with no acclimation. Whether indica, sativa or hybrids...they've always dealt with it just fine. :thumbsup:

Yes, you can use the HPS from seed to harvest, but it's kinda overkill using HID lights for seedlings.
