I have now built and planted tomatoes in my windowfarm with a 200 l reservoir. I hope this will be able to keep the plants happy for long warm periods unattended.
My farm consists of 8 hanging pots that are supplied with water from a t-joint airlift and three large boxes that get water through some pieces of yarn. The reservoir can hold more than 200 l of water and I have added some liquid nutrient in the water.
I am growing tomatoes in the hanging pots and in the boxes I have an ash, rosemary, maple, rowan and white clover.
So far, the plants seem to be fine. Some of the leaves on the tomato plants have some white patches. I might need to adjust the amount of nutrients in the water, but that is just a guess.
