The Bucket System
The bucket system is an easy system to setup.
Drill a 50mm dia hole in the lid
Fill the bucket with water and add your growing solution - I rotate my growing solutions to ensure that the plant is getting its required nutrients plus I also add Potash [soluble] to the solution for disease prevention.
Place your seedling into a container with holes for the roots to grow and develop then place the seedling into the 50mm hole.
Where possible airate the solution every 2nd day . [I use a small fish tank pump].
