Grow media has become the next best thing since, well, since actual natural garden soil.  And, in fact, probably better.  In addition, that is the point really.  Good grow media has to be used with aquaponics, you cannot use garden soil in aquaponics.

 

 

When you grow your plants indoors or in a confined space, you want to ensure they are getting the best nutrients to their roots, more than enough air and water, are allowed maximum room for their root growth and can be physically supported as they grow.

 

Grow media can offer all this and more.  However, it is important to choose the correct grow media that fits your budget and is suitable for aquaponics.

When it comes to choosing your grow media for aquaponics, it’s important that media not be too small, so it doesn’t block your pipes. The more surface area that media has, the better, as this will mean more beneficial bacteria to convert the fish waste to food for your plants.
