So i am growing 6 auto flowers right now they are about 1 1/2 weeks sprouted out of the ground looking great and currently i have the 400w gavita HPS in the socket because it has a higher lumens then the MH correct? Should i still have the MH in and wait to use the HPS untill i see flowering? Thanks starass

What you said is correct. switch to hps on flower.

use mh until upward growth has stopped. keeps the nodes nice and compact. then put the hps in to fill up the buds.
