Ok so here's the setup thus far:

Veg/Flower phases:
4'x4' space, about 6' ceilings.
430w HPS Son Agro system/bulb in cooltube w/ batwing reflector
250 cfm fan w/ ducting to outside for cooling light system
several smaller fans circulate air around the plants for proper venting and to increase strength of stems

Mother:
flouro light (what's going to be optimal to keep her healthy and flourishing?)
organic soil

Clones:
rockwool
flouro light



I'm currently growing clones for 2-3 weeks in veg before switching to 12/12 for flowering to provide my plants with a good opportunity to establish themselves and give myself slightly larger bud size at harvest. The entire area is cooled with central air and kept at ~70-72 degrees constantly. I'm also going to go with a scrog setup and a good big bud x nl hybrid a buddy of mine and I have been working on for the last 6 months (we had several smaller stealth grows setup during that period and developed our cross from some seeds we'd saved over years of high-end weed deals :rastasmoke


Questions:

How much benefit would I get from upgrading to a 600w HPS (or 1000w HPS for that matter) or a 400w HPS + a 400w MH (I'm assuming that in order to get full benefit from the MH I would need to increase the veg time to get my money's worth on the bulb/ballast correct?) or by going to dual 400w son agro HPS's?

How much would hydro speed up harvest time, increase yields, etc... ?

What's the optimum number of plants for me to run in this setup to maximize potency, flavor/aroma, yield, etc...?

How much benefit am I going to see from adding CO2 enrichment to the grow space?

I've grown before and, from what I can tell, have a better than average grasp on the concepts used for indoor growing, be they hydro, aero, soil, etc... but that doesn't give me much in the way of numbers or quantifiable benchmarks. To try and get a better idea of what to expect with this specific grow in terms of bud potency/size and yield as well as where I can improve, I figured it would be best to ask the community here for input.

Much thanks for any help y'all can provide!

Peace :hippy:
