nice one temps are spot on in the room now,22-25 lights on,18-20 lights off,looks nice have no probs with bud development just never seen the red in the stem before,thanks for the reply take it easy.

You dropped what? While doing what? When?

Red stems may just be a trait of the plant. I've had them before and the plants turned out just fine.
