Ok, so Ive decided to go with an HPS light to grow my girls in Flowering stage.
Right now they are only 7 days out of cracking from the seed, so I have time, but ideally want to order my light now.
What I am confused on is this:
What all do I need to buy? From what I can see I need to buy the ballast, the bulb itself, the reflector/cooling vent hood... anything else I would need to buy? Do you have to purchase the "bulb scew/housing" for inside the hood?
So here are some factors that Ive been mulling over on WHAT type of light to buy...
1) I was told by my local grow shop owner that a 400w HPS shouldnt need to be vented. This is based on my grow area that is a 8ft x 5ft deep room. Is this true? I live in a tropical climate with AirConditioning inside, so Im thinking I don't need to vent this light for HEAT purposes, right? (So thinking I don't need a vent hood for 400w)
2) I've been reading about HPS/MH switchable ballasts. Since I'm using Floro's to veg at the moment, I think it would be "better" to veg under MH... so should I get one of those digital switchable ballasts? Any reason not to?
3) I plan to duct this bathroom in a few weeks to prep for the flowering smell with an inline fan. The room is already plumed for exhaust, so I just need to hook up to it with a cabon filter. Should I just bite the bullet and upgrade to a 600W
(rather than just the 400w) and throw it inline with the fan since its only a couple bucks more? Or is 600W overkill for the 12 plants I plan to put under this light?
Thanks for all the help ahead of time!
