Two Pot Grow System
Make a system hydroponics system by slotting the 18 Litre square pot with holes into the 24 Litre bottom bucket.
The bottom bucket is deeper creating a small reservoir. Fill the top pot with the growing medium, and drip feed. The nutrient can then drain through to the bottom bucket where it can be discarded or recycled.
Join as many together as required with the use of Tub Outlets.
