Thank you, iamhigh...I'll expect tall and stretchy plants as one side effect of trying outdoor strains in a closet and try switching out bulbs and light cycles earlier...what say when the plants are 10 - 12" tall?

In my current crop, I switched out bulbs and light cycles when the plants were 15 - 18" tall. Now with pistil withering underway, my tallest NL is about 38" and they've all stopped vertical growth.

I've noticed that wide internode gaps aren't necessarily bad. Placed 12 - 15" above and a little off to the side, my 400 watt hps reaches most of the stretchy plant yielding many smaller well-shaped conical buds whereas it penetrates only the top third of the compact plants.

Thanks again.
