PARK RAPIDS -- Come learn the basics of hydroponic vegetable production from Barry Thoele, a grower with 20-plus years of experience in hydroponic growing. This workshop will feature the basic science, construction, and operation of hydroponic systems. Hydroponics is the cultivation of placing roots in a liquid nutrient solution rather than in soil.

This presentation will be held from 1 p.m. to 4 p.m. on Saturday, March 9, at Northwoods Bank, 1200 E. First St. in Park Rapids. A light snack will be provided.
