why is my basil so sparse?

Doug says that you divided up the plants when they were growing so you have some root damage. Putting a root damaged plant out in the full hot sun is a recipe for disaster to begin with no matter how much you water the pot.
You don't say what your feeding or watering system is but I can tell you that unless you're feeding at least once a week and keeping this plant slightly damp (never letting it dry out) you're going to have problems growing it in containers.
You also don't say what soil you're using in the containers so if it's garden soil, you're up the creek again (compared to peat based artificial soils).
Let me suggest you check out the info on container gardening on this site and then check out the seminar on container gardening at my Doug Greens Garden website.
Good luck with the recovery.
