Hi guys.im growing wite widow autos and using a mars pro 2 1200w should I be using veg setting until flowers start then turn on bloom. Or should I be runing both settings all the time
As always thank you everyone here is awesome

I am pretty much doing what you are. I keep both lights on because as I understand it that would be full spectrum.

First welcome @Tirod After they get 6 to 7 inches high I would go ahead and swap to both veg and Bloom.

I have an old Mars unit and asked the same question directly from Mars. They told me to run veg. only when in veg. and both when switching to flower. I know many, however, that do run both at all times. Good luck!
