Grow Box Advice CFL's + 150W HPS Soil System

Waddup fellow tokers

I have recently decided to stop growing outdoor and temporarily grow only indoor for the time being.
After doing hours of research and jibber jabber with my best mate and grow partner we've decided on a mother/clone system and also a separate seed sprouted plant section that will be under Scrog.
These will both be accommodated in 2 separate stealth boxes with a 3rd for drying. I however will be doing the seed to harvest strategy under scrog to my growing until I have sufficient knowledge to do a proper strained mother/clone harvest strategy.

List of equipment:

150w HPS system
Mylar reflective material
3x23w CFL's
Veg/mother-clone cabinet Hybrid 100cm H x 30cm W x 30cm L
Flowering Cabinet/Scrog Hybrid 100cm H x 80cm W x 80cm L
Bio-Bizz Neuts
Bagseed

What I want to achieve from my grow boxes:

perpetual harvest of 15-30g's every 2 weeks for personal medical consumption with minimal plants at a time.

Advice I would like from the professional growers I've seen on this forum :

How many plants at a time should I be growing? Keep in mind that my location/country its illegal to grow on any terms, so stealth and minimalism is needed.
How many grams (dried) can I look to harvest off the advised amount of plants?
Suggest a simple feeding plan and light schedule to achieve my goals?

Thanks in advance and I will post pics of the box's when they're ready to grow

https://www.rollitup.org/grow-journals/131013-master-kush-scrog-150w-hps.html this is a 150w SCROG grow done in a mini fridge. To sum it up and save you some math; the guy used a small screen 15"x18" yielded 3.5oz total giving him .36G a square inch. He decided that only 1.5oz of that was smoke worthy giving him .15G a square inch. He did a really good job jamming the plant and filling the tiny screen so the numbers may be skewed a bit. I think tho, its something to shoot for. BTW the other 2oz that weren't smoked he used for making canna-butter I believe. Hope it helps a little!

Just worked out the math for you 31.5" x 31.5" = 992.25sq", 992.25 x .15 = 148.8375 grams, 148.8375grams/28grams = ~5.32 Oz -- keep in mind that is on the low end and the fact that you have a larger space and will need to at least supplement with high power cfl's if not double up your 150 -- a 400w might fit your grow with proper ventilation but don't take my word for that ... do your research. [edit] as to your # of plants question to reach the numbers I mentioned you'd need 4-5 but figure 1 plant = 1 - 1.5oz's
