Excuse my ignorance (new this year to growing also in containers) but what is the purpose of the vertical PVC pipe in the corner of the E.B.? Also, are drain holes to be drilled in the bottom / lower sides of the plastic containers for drainage.
Below is a photo of my container section. I have my pots sitting in basins, which retain about an inch of water after irrigation. Will the "wicking" action of the soil keep the growing medium in the containers too moist, and should I just remove the basins and let the excess water just drain out to the ground, or is the wicking effect beneficial to stabilizing the moisture in the container?
Thanks for the help,
Ray
