We have our own Bokashi system that gives us Bokashi juice and compost. However, composting requires time. This is why we sometimes order compost.
We order at Bio-Kultura, because they sell organic soil and compost - plus, we get a discount with them. So if you want to order, you can send them an email and ask for the business prices. Attached you can find the order of October 2019 and April 2020.
You need around 320 liters of compost to fertilize all the grow beds over a year's time, that comes down to 8 bags of 40 liters.
Transportation costs are always € 38,50 per pallet. This means that even though you have 1 order with soil and compost, you will pay double the transportation costs.
