How to sow tomatoes in capillary boxes

Is there anything better than the taste of tomatoes that have grown sweet and juicy in a warm greenhouse? No, right? That might have something to do with the transport of self-cultivated tomatoes. The transportation from the ground to the table is reduced to just a few meters.


The Danish garden enthusiastic couple, Nanna Nørholm and Frederik Skovgaard, has on their Instagram profile “Udkansk” made an Instagram story which shows how to grow tomatoes in capillary boxes. Juliana has gotten the green light to make their stories into a guide. The couple is from Denmark; hence the text of the stories is in Danish.


Good Luck!


What you need:

A capillary box

A growbag

Two tomato plants

Lots of water


A capillary box is a polystyrene box with three “funnels”. The system is made in a way that the box works as a self-irrigating unit when you put a growbag on top and cut three holes in the bottom. You should fill the “funnels” with some of the soil, so when you fill the box with water it can get into the soil.
