In this study, a gel/liquid interface is utilized for growing a new (calcium‐phosphate)/carrageenan garden. The hydrogels are made from carrageenan loaded with either sodium phosphate or calcium chloride, while the interfaced solution contains a source of the salt not used in the hydrogels (i. e. the sodium‐phosphate hydrogel with the calcium‐chloride solution and vice versa). The physical and chemical properties of tubes grown from both systems of the same amount of carrageenan have been reported. Interestingly, when varying the amounts of carrageenan (and thus controlling the stiffness of the phosphate‐hydrogel system), it is possible to control the thickness and height of the tubes.
