Aerogarden Lights vs. Pump Settings?

Reading all I can about using AG for weed. Most users add lights which are controlled externally with a timer. What of the pump? It stays on all the time? I have started an auto bean in my AG and it's growing freakishly fast.

You say that like it's a bad thing. Can't speak for AG, but a in homemade system I made, the pump ran 1 minute on and 5 minutes off 24/7.

I think the AG has the pump on 24/7.. Not a bad thing at all.. Just amazing that the little bean that began germination less than a week ago is now sprouting! I looked at the roots and it's already almost 3in down into the pod. Faster than expected!
