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
why dont u use both?????????
it's hard to say man. but you really dont want blue spectrum on your flowering plants and you also dont want such low wattage too.
I would say go for a bigger HPS (it's not much more to upgrade) because thats when power really counts
just buy a mh bulb with added red spectrum
how big of a hps dou think would be good, and about thow much would it run me?
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.
how many plants??? and or how big of a grow room??Quote:

my advice. If you are deciding between two lights say 250w and 400w go with the bigger (As long as you can afford) b/c more light more buds and if you ever decide to grow more you'll have the capacity.
thats a good point. you also want to take into consideration, 'how many females are you going to be left with?' unless you are going with feminized seeds, i wouldnt expect all 4 to go the distance. either or will be fine if you have the money, but if you only end up with 2 or even 1 female, 400w would be alot of energy to spend on just 1 plant. its all about the benjamins:DQuote:

have a good one =)
