So, a couple of questions.
You are using 32 ounce jars for some. How often do you find they to have water/nutrient added for, say, a large sort of lettuce or kale? Any benefit or pro/con for a one-time filled bigger container versus topping up a small container?
You fill them back up with the same as the initial mix?
When you finally harvest a jar, can you just top off and reuse the same solution? Any limit on that, or does the water just eventually get nasty?
I see you don't use things like seed sponges. Does it work okay just seeding the clay pellets directly? Do you have to make sure the liquid begins up at the level you drop the seeds, of does the clay wick at all?
Any comment on the difference between using jars and using much larger buckets and containers holding multiple cups? Do you feel your plants get a large either way?
Also, I am going to put a rack on a semi-enclosed back porch. One side is a house wall, one is a glass wall, the third glass wall sliding doors, and the fourth screen windows with louvers. How important is the ambient temperature? It would never freeze, but in parts of winter, it certainly would get much colder than an inside room or a basement would get.
Jars seem to offer a lot of versatility for the small grower, things like shuffling jars between shelves to keep the lights right height. I saw someone, I think Indian, being very frugal and using a found big plastic bowl and just some sort of rescued plastic laid on top with holes and cops.
