I'm trying to make an automatic beetroot farm. I'm using observers behind the plants and dispensers with water. Each plant has 4 observer stages. The observer is triggered when:
- the seeds are planted.
- the seeds grow one stage.
- the beetroots grow another stage.
- the beetroots are ready to harvest.
The obvious solution is to make a kind of counter that waits until the observer has been triggered 4 times and then triggers the dispensers. I am not sure how to achieve this, although I imagine it will involve some sort of hopper with 4 items.
How do I achieve this while still keeping it compact enough to fit in a beetroot row?
(I am doing one dispenser per row, and I will plant the beetroot that triggers the observer last so that all the beetroot will be harvest ready when the dispensers are triggered)
