just like the title. when do you switch your mh to hps. the same day you switch to 12/12? the day that sex is apparent? when the buds start to grow? i usually switch bulbs when i change the light schedule but i'm curious what you all have to say.

I also switch bulbs when I switch the light schedule. I think that is the only way that makes sense if you are going directly from veg cycle to flower cycle without a phase-in. This question becomes an open debate if you are talking about transitioning the light schedule over a week or so, such as subtracting an hour of light a day until reaching 12/12. If I were to do that, I would still switch the bulb at the start of the transition.
