Hello all, This is my first post after many informative learning sessions. This is my first grow, I'm running 600w mh/hps in a 31"x 31"x 71" tent. Been up and running beautifully for a week and when I went to check on my baby girls about 2 hours after lights on and....the lights WEREN'T on but fans and ballast we're running. My mh bulb blew, yes after only a week. I quickly replaced it with my hps bulb since the temp had dropped under 60°F. I still have a warranty on the shoddy bulb so it will be replaced, I just don't know when. My question is this; Will my plants be ok after going from mh to hps after a week, then back to mh when I get the new bulb? Will this cause undue stress or unwanted hormone changes that lead to stress? Or anything that might negatively impact the life of my plants. Would it be best to just leave them under the hps for the rest of their cycle? Anyone have firsthand knowledge of this issue?
