Feed sack containers are the least expensive of all the containers to grow plants in.
Due to the pores in them they are quite suited as containers to grow various vegetables.
Feed sacks come in different material: hessian bags or woven plastic bags.
They are good for one season and may have to be replaced every growing crop.
To construct a feed sack container, pour the growing medium into the feed sack and close the open end using a twine.
Place the feed sack on its flat side and cut 50 to 75mm square holes.
Soak the growing medium and plant the seeds or seedlings into the holes.
In this situation I prefer to plant seedling growing in Rock Wool, this enables the seedling to continue to grow without going into shock.
