I planted basil in the upper 20cm deep vat.
I planted onions and chard in the 30cm deep medium-sized tub. They go well together and both tolerate drought fairly well and have the same water requirements, i.e. they don’t need much water.
I planted tomatoes in the large 40cm-deep lower tub, which go well with basil and chilli peppers. Normally, 1m2 can accommodate one and a half (1 &1/2) tomato plants. With dimensions such as 80*40*40cm, I have more volume and I’ve accommodated 3 plants.
I combined onions and carrots in my pots. It’s true that in terms of density, they risk being cramped when they’re growing. But I trust their intelligence to develop. There’s room for everyone. What’s more, I’m not obliged to harvest large vegetables, but smaller, young vegetables with just as many (or even more) vitamins and nutrients.
If you’d like to play around with the different depths, I’ve given you some suggestions in the photo gallery. As far as the ideal substrate equation is concerned, you need to bear in mind the concepts of ecology and economy. There are plenty of alternatives to vermicompost and sphagnum moss.
Greener. More local. More economical. More coherent. Let’s exchange ideas here?
