There are a number of advantages to using a spiral grow tub, says Dr Stephen Fagan.
“You can grow up to about 50 plants in it and that’s good for a family of six.
It also allows you to keep the temperature low.
The tube itself is much more than a pot.
It’s a container.
The tubing can be removed and used to grow a wide variety of plants.”
A spiral grow system can also be used to produce seeds and fertiliser, which can help to increase yields and to prevent pest problems in your garden.
