Hose 'n' Fert System
This fertigator system is easy to use and saves a lot of time when fertlising or treating large numbers of plants.
A video of the system is available here: https://www.youtube.com/watch?v=bHsZpb1OKUo
We found that a 4 litre bottle with a small hole cut in the lid for the flexible tube to fit into was easier than a bucket holding the fertiliser.
You can use this system with any fertiliser, insecticide or fungicide.
