Maybe more fancy than you need to do. I would install whatever you need to as maybe a second door accessible from outside of the room. Then no worries about light leaks to flower room. And your veg area doesn’t necessarily need to be light tight anyway.
I think whether you do pocket door, bifold, or standard door, it’s probably best way to go.
Sounds like you could make pretty small veg space and shelf it so it has basically upper and lower grow area. 2’ deep and maybe 3’-4’ wide on 7’ wall would give you room to put another door.
U going to grow autos, n photos, no clones? Pick a light for cracking, n build ur space for that light. I got a sf2000 with adjustable lighting, n ratchets for propagation the light is perfect for the 2’X21/2’ space I built for that procedure. Adjust ur light n height as needed. It’s n the same area as my veggy space separated with Mylar curtain. That left me with aprox. 4X4 for veggin I found for quality control purposes 3 r 4 plants veggin, wasn’t even close for my needs. Now I’m talking continuous grow here. So I needed a 17" to 19" plant to replace the harvested one every 10 days, to allow 10 weeks for flower. Pulling a plant a week. Easier said than done. So get ur light to fill that space, whatever light u choose to use, LED probably. My door is n the front, so when I open, cracking on the left, vegging on the right, both set on same light cycle. My flower space is next to veggy, separated by a set of stairs, u build a wall to separate the areas, with a door n front. Two separate rooms easily vented, well lit, n easy to clean. With my state legalizing medical grow, I’ve made some changes to b legal, but we’re just spit balling here. Good luck I hope everything works out for u my friend…
Room layout is exactly what I was thinking. Only instead of autos I would cycle plants into flower room from veg space. Any time you can spread out work load is usually a bonus. If you can take half the room every 4-5 weeks or even a single plant every week or two isn’t as overwhelming as having to drop a whole room at once. Just my perspective as a guy working 60 hours a week and having to come home and change diapers lol.
This is my current grow space. I was playing around with an existing storage closet to convert it to additional grow space. I am retaining this closet and expanding elsewhere. I am giving the layout so you can relate it to the space I converted to vegging / seed starting etc. I decreased the number of floor cabinets and moved them to obtain a 36" wide area
I had to take out another shelve because I needed the additional height until I figure out where the plant in the 5 gallon SIP bucket is going. I added some mylar which I will retain when I put a shelve(s) back
Because I use a tent, I do not need to be concerned with the veg light. In your case, being able to have the 2x4 area described by @PharmerBob open to the basement, would simplify things and give you the most flexibility for the flower area.
I have to put pencil to paper to lay things out to see how it works together.
Good luck with the project.
I’d consider prioritizing cold water (hot wouldn’t hurt) and a drain. Maybe you have a slop-sink somewhere else, but those are really convenient. If you’re far from a waste line, you can look at macerating sumps, or just use a less-expensive condensate pump cautiously. I just know that, for me and my back, having water wherever I need it instead of carrying it is huge.
I’ll be watching this, and I’m happy to help you detail it out.
Crown is on inside casing of door frame and mounts flush with door, this creates another barrier for light to have to escape.
Now I have to be honest I don’t allow anyone in the area during lights off and I’ve taken out the ability for the family to turn on switches that would cause issues
