Hey guys,

I have two questions,

1. will it be ok to use both HPS and CFL (soft white) together while flowering?
HPS at the top, CFLs at the side

2. Is MH works as much as HPS does while vegging?
I'm in dellema here to go either with :

a) CFLs to veggi then HPS to flower
b) MH to veggi then HPS to flower with HPS/MH switchible ballaster
c) Use MH convertible bulb which works at HPS ballaster for veggi,
then HPS with same HPS 'only' ballaster to flower

Reason is, obviously HPS only ballast is much cheaper than HPS/MH dual ballast,
and at the same time, I heard that while in veggi period that light is not that
important compare to flowering, so why not just CFL during a veggi time
(save some bucks)

Any advice?
