That sounds just what I need, didn't want to go the hydroponics route but we also have sandy soil and water just does not stay in the soil, so thought that hydroponics would be the solution but wasn't sure that it would be chemical free. I also feel vegetables should grow in soil, giving us nutrients from the earth. Thanks to Greene's answer I checked it out and wasn't happy with what I read. Here we have a product called Nitrosol, which is a liquid organic fertilizer, I can use that in the containers.
Thanks so much, getting excited about my vegetables I'm going to grow already. Our summer veggie season is starting now so will be able to begin straight away.
