I think your question is about light?

HPS do not use the same ballets as a MH light. Are you switching your transformer or is it one of the new switchable ones?

If you are ready to flower you need to switch to the HPS light. MH does not have the proper spectrum to flower. However they do make a few Mh bulbs that are enhanced spectrum for flowering in a MH transformer.

I bought a 400w MH highbay...after research, I decided to change from standard MH to Agrosun GoldMH w/ enhanced red spectrum......Another thing if I might add...Take the light apart and get rid of the dome...less radiant heat and more light exposure
