HPS for flowering.
MH for vegetative.

Fine...

I'm thinking that during flowering, the plant will have what it needs from the HPS... but, if you add a MH, you'll help it in various other processes that it still runs. Even though it's flowering, it isn't like it "shuts off a switch" to the MH spectrums...

At least, those are my thoughts...
turtle420 Reviewed by turtle420 on . MH AND HPS during flowering??? I have a 1000watt MH system with a conversion bulb in currently for flowering. I heard a nasty little rumor that if you run BOTH MH and HPS to run BOTH spectrums of light during flowering that your buds will be more potent... Is this fact or fiction. If fiction, what CAN you do to ensure maximum potency? If fact, I have a 400 watt HPS with conversion so I can run 1000Watts of yellowish orange light and 400 watts of blue. Rating: 5
