Both would be good, you will get more per watt with a HPS but its allot less watts. get a 400W HPS....you could probably find some for around $100 if you look hard enough.
Cyclonite Reviewed by Cyclonite on . mh vs hps ok I have a 400 watt mh light that i will be using for veg growth, but i was thinking about buying a 150 watt hps for flowering. My question is would i get better flowering from the 400 watt mh because it has more output or would it be better to use the 150 watt hps because it has a better spectrum for flowering? thanks in advance Rating: 5
