Is that a soil pot in the middle of the grow bed? I'm no expert, but I feel like that could cause you a lot of problems, especially if it has nutrients already in it. Also, doesn't the soil get too wet? You might want to consider germinating your seeds using the paper towel method, and then transferring them to a soil-less option such as rockwool. Then you wouldn't have to worry about cleaning the peat off.
Here's a link for rockwool off of amazon:

I honestly don't know how much time I spend with it but i doubt it's much. I check water levels, test it with digital meters, and make any adjustments based on those readings 3 or 4 times a week. I don't really do a "harvest" because we just grab what we need when we need it.
In terms of cost, it can get somewhat expensive if you don't do your homework. For example, buying pre-mixed liquid fertilizer like this is easier to use but you're paying a premium for water and food coloring. You can get water soluble powdered fertilizers and add epson salt, which provides micros. I can't make a recommendation on those yet as I'm still testing various blends. I'm also going to try compost tea soon.
You'll also need a material to start seeds in. Rockwool is the most common but it can get expensive if you're just getting started because you'll likely kill a lot of plants. There are alternatives like coconoir but it is the easiest substance I've found thus far.
Finally, you'll need balancers that you'll use to adjust PH levels. That's something you won't need to buy often though.
Might be helpful if you post a few pics of your setup.
1: 18-24 inches. make sure you have good airflow over plants to minimize tip burn. Us a small fan if you can.
2: If you are only growing lettuce and harvest fast enough, you should be fine. The distance between plants is more important since lettuce will take up at least 8-10 inches per plant.
3: I have great luck with these rock wool cubes that drop right into 2 inch net pots after they germinate and send roots out (10 days or so) :

have fun
Thanks!
When I looked up sea of green, I got this, would using these work?
Sorry for all the questions, this is all a little overwhelming.
If you want simple, cheap and portable then DWC is the way to go. My DWC lettuce setup was super cheap to build and can be moved around easily, and I've had several very successful lettuce grows with it. I just bought a $15 container store plastic drawer and drilled some holes in it for net pots, and piped in some air for airstones. I used two of these powered by one of these. Medium is rockwool based in clay pebbles housed in standard plastic net pots.
So tallying it all up...
Container - $30 (could probably have found something much cheaper)
Air pump - $16
Air stones - $6 x 2 = $12 (could also have probably gotten away with smaller/cheaper stones)
Net pots = $6 (for a dozen, so that's 9 sites plus 3 to grow replacement seedlings to swap in)
Clay pebbles = $10
Rockwool = $16 (for a sheet that will last you through many harvests)
Lettuce seeds = $2
Grand total = $86 for absolutely everything needed (assuming you're using sunlight) you need to grow.
There's a few places I noted where you could probably buy cheaper than I did, so You could probably do the whole thing for under $70.
In terms of tools for assembly you will need a dremel or something similar to cut the holes, since the plastic is pretty tough. I suppose you could manage with some very heavy duty shears, but it would probably be a nightmare to cut by hand. And a drill for the air hose holes. Some black spray paint to keep down algae growth in the water supply would be good too.
Can't speak to climate, but leafy greens are pretty hearty and have continued to thrive during a few very high temp days here, so I suspect they'd do fine in Florida temps.
