To ensure good hygiene, place the polythene sheeting underneath the bag.   Cut 3 or 4 drainage slits around the outside edges of the bag, approximately 10 mm from the base, to remove any excess nutrient solution.

Cut holes in the top of the grow bag to allow plants to be inserted.  Four to six plants per bag is usually sufficient, but the number will vary according to the type of plant grown or the size of the bag.

Thoroughly soak the medium in the the grow bag with dilute nutrient solution, before inserting the plants.  Plants should receive nutrient when required.  Use a plastic watering can or drippers to apply the nutrient solution.
