1. Start by beating the growbag so the soil is loosened and mixed.

2. Put the capillary box in the greenhouse and put the growbag on top of it. You can put the capillary box in a capillary box planter. Now cut off the plastic on the top of the growbag and irrigate the bag thoroughly before transplanting your tomatoes, as the soil should be well moist. Cut two holes in the bottom of the bag, where the growbag meets the capillary box. (You can remove the soil and cut the holes from above with a box cutter. Make sure you fill the three holes in the capillary box with soil.

3. It is time to transplant the tomato plants into the growbag. Tomatoes get big and need space, so Frederik recommends putting a maximum two plants in each growbag. They take up a lot of space in the soil, so it is important to keep some space between the plants. Make a hole in the soil above the “funnels” – tomato plants are different from most, as you can plant them deep in the soil. If you plant the tomato deep in the soil you get a more stable plant, as it can send roots from the sides of the buried stem. It is quite spectacular.

Remember that the root collar is a bit sensitive, so make sure to transplant it in the same depth as it was in the pot. The soil may cover the root collar just a bit.

4. A small tomato plant like this grows quick and gets big, so make sure there is room for it.

5. Finally, you can fill the capillary box with water in the small hole in the corner. The box can hold a lot of water, which means you don’t have to fill it that often.

6. As the tomato plants grows you need to snip off the corner shoots.
