You should give the DLI it can handle without damaging the plant. If the specs are accurate for your lights, it's an easy process to guesstimate DLI. If you can do this in 16h or 18h that's fine. More hours above local max dli (depends on local variables a bit) is wasted electricty and stress on the plant. Also, you want a dark cycle. I'd only do 20/4 or greater hours of light if the light is underpowered and that's the only way to max out DLI relative to local variables.

Airpots allow alot more air than fabrics to reach roots, meaning the medium will dry at a faster rate than fabrics. Nutrient can only uptake where moisture is present. I have personally grown 3 airpots 1 fabric and noticed undeniably the airpots dried substantially faster than fabric pots. Nutrients can only uptake where water is found. If 1 pot is drying 20,30,40% faster, the production line is halting. Mediums that regularly go from one extreme to another can cause calcium to have problems with uptake too which would effect final produxt product.
