Hi I set up 6 150 Gallon Rubbermaid livestock water troughs as wicking beds . I put 6' drainage pipe in as a water reservoir covered by a foot of sand . That is total depth of sand including the drainage pipe of 12" . Then landscaping fabric . The growing medium is 50% peat moss mixed with 50% cow/ mushroom compost . Also some vermiculite , perlite and lime . The wicking action is not great so i am watering from above as well as from below .Growing medium is 10" deep .
Did i make a mistake by using sand ? Would sand be OK if i used less in terms of depth ?
Your insights would be appreciated .
Thanks
