Subbed Nivek. As a past bonsai enthusiast this one is interesting. Love the raisable light system. Brilliant adaptation. That's some sweet training you have going there as well.
Tulip has an amazing thread on CFLs that I'd recommend. It's what I've used as the basis for my own grow, which is clicking along with amazing ease.

The basic plan is 100W per plant, and the 23W bulbs turn out to be the most efficient lumen output. Your shooting for at least 10,000 lumens over square foot. Do feel free to exceed that. I'm growing two autos and as of today I have surrounded these bushes with 390W total - ten 23W bulbs split between six 2700 lumens and four 5000 lumens with four 40W 2700 lumens used as canopy lights (2 over each plant). That means I'm flooding these beauties with 23,200 lumens. It's important with CFLs to always have a mix of spectrum. The only exception to this is with seedlings, which aren't a concern for you.
To get really dense buds with CFLs you should work out some way to get some serious side lighting as well.
I laughed right out loud when you mentioned the grandkid's parents not understanding. I share that frustration and need to practice stealth with a child who should know better.
It will be fun to watch you work through the challenges. I like your style.
Edit: flat Ultra-white paint on that light panel will give you better reflective properties than the foil. Worth a thought. Love the grow space.
