Yes. As you might have understood, the Groasis Waterboxx® and Growboxx® plant cocoon are a part of the planting technology. Its function is to bring the roots 3 meters deep in the first planting year. The box contains only 16 liters of water while a big tree maybe evaporates 10 liters per day. Because its roots are over 3 meters deep within one year, the tree takes the water from there and it survives without the box. For this reason we take off the box after one year and use it to plant the next tree. The advantage of the Growboxx® plant cocoon is that we leave the box and that he creates optimum circumstances even after a year, since the Growboxx® plant cocoon while degrading will keep a bit humidity around the stem and will cool down the soil around the stem.
Never mix the idea of planting technology (= Groasis Ecological Water Saving Technology incl. Waterboxx® and Growboxx® plant cocoon) with irrigation (= giving water while the tree is big).
