The Kratky Method
Author Food and Agriculture Organization of the United Nations.
The Kratky method: Another simpler approach to ensuring sufficient oxygen for plants roots using the DWC method is to leave a space of 3-4 cms in between the polystyrene and the water body inside the trough.
This technique is called the Kratky method which sees the polystyrene sheets suspended 3-4 cm above the water rather than floating on top to allow air to circulate around the plant roots.
This approach removes the need for air stones in the trough as sufficient amounts of oxygen in the air is supplied to the roots.

About The Author
Gardening has been the greatest adventure in my life. I began at the age of five working with my mother in her garden and in my grandmother’s garden to feed the other 5 children and Dad because we were poor. By the age of 6, I hated gardening. But the one thing I loved was Flowers.
Yet throughout the years I began to admire both Mother and Grandmother for all their efforts and hard labor. I finally fell in love with nature and the magic of what gardening can actually be to those who love to create them.
As you may know or do not know there are many types of gardening and I absolutely love them all. I have created this website not just for me but for you as well. A place where you can learn and create your own gardens to your taste.
This is a Membership website – I wish this to be not only a learning site but one where we can exchange thoughts and information as well explore all the different gardening techniques.
The membership costs are only $19 per month and will give you a great adventure into the works of all types of Gardening. I look forward to meeting all of you that join. We are going to have a Blast.
Warmest Regards, Coyalita
