Getting ready to transition using 400 hps

Indoor Growing Lighting

@Donaldj I know you HP lights. When I transition I’ve read to only use 50% during that time. Since I’m using 400 HP with dimmable ballast should it be 50% or 75%. Thanks

I use MH for Veg and a HPS for flower. If you are referring to the transition between Veg and flower I go %100. I just put the light up higher to start and then lower it down after a few days.
But I usualy leave the MH bulb in when I switch to flower for a few weeks to help with the stretching.

Most companies don’t ship until payment is received. After payment it took 10 days

I typically run my 400w HPS 100% during transition always worked fine for me less stretch was my goal with lower watt HID’s

Thanks for your text. Knew you used HPs and wanted to know as some say to transition @ 50%. Heats been such a problem I’m sticking w/400 . Yield will be just a little smaller, right

Less light equals less yield in most cases

Quite a bit less? I was going to invest in ballast to handle 600 on next grow. I’m I stupid to wait? Will yield be considerably smaller or just smaller buds?

master the temps first because a 600w is a lot hotter
