If you could split the closet all you would need is a ballast and hood.

Good light and good advice your getting. However do you under stand the difference between wick and DWC (deep water culture) ? You want to look up DWC. I had a drip dwc. You can drip the whole grow but you don't need it when the roots hang in oxygenated water. Just to get clones or seedlings started. Just an airstone a bucket or container some netpots and hydrotron maybe 1 inch rockwool for clones and seeds. Nutrients and cal-mag. about oh 100 bucks but worth it.

Jump in it's easy. Oh, hydrotron are expanded clay pellets that hold just the right amount of water as to not rot your root.

We must figure a ventilations system for you and what about the smell. I went to my bro's house and could smell 14 inch papaya's 5 feet from outside his door. You can't smell plants when you live with them. LOL
