Gonna go in the yard and dig for earthworms. Try to find at least four for each container. Should reproduce with four in a box. Earthworms should aerate the potting mix real nice. Can not find worms I will go to a bait shop to get some.
Vegetables plants are still green. 
Had a decent rain last night. Potting mix is draining very nicely. It should seeing I cut enough 1/4 inch slots in the five inch wide boards I used for the bottom and sides. Want the potting mix moist, not flooded with water.
May go to Walmart at some point in time and purchase an electronic PH and water content meter which comes as one unit.
