Hello all just hear for some info. Mly last grow i grew under a 400hps and it did the job for veg and flowing but i had pretty good results all in all. But in my reading ive read that an MH bulb would be better for veg and switch over to the hps when you get into flowing. Does anyone have any experience in this would i be wasting money getting the MH bulb does it make a big difference in yield? Any info would be appreciated thank you.

The MH is more of a blue light so it is a bit better in early to mid veg. Can help keep the plants a bit smaller with tighter node spacing while building a better stalk and root system. While HPS is the flower power. Back in the oldin days many of us ran both in say end to fixture setups to use both bulbs through the complete grow cycle. Some switched bulbs out. While many others just ran straight HPS. Most didn’t run MH full cycle.

@Blastfact thanks man! I seen that BH is more on the blue spectrum and thats why they say its good for the veg i just didnt know if it would be worth running for veg and switching to hps during flowering. Or if the diffrence isnt that big and just stick with the hps through it all.
