id say get a 400 hps... and use your mh for clones/veg. and make a harvest every 60 days..... dont worry on the 400 hps compared to mh (the watt to lumen ratio is different) because hps still has the advantage with lumen and spectrum output..

have a good one =)
ronjohn420 Reviewed by ronjohn420 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
