A tap (1000) for the controlled dispensing of water is described and claimed, comprising: a hollow column (1100) that is positioned vertically when in use, having a first end and a second end; a cartridge housing (1200) inserted into said hollow column (1100) at said first end, a cartridge (1300) of cylindrical or conical or prismatic or truncated pyramidal shape, adapted to receive at least one inlet flow of water from below and to supply an outlet flow of water from below or laterally, and adapted to perform a flow control action and, if necessary, a flow mixing action, said cartridge (1300) being inserted into said cartridge housing (1200), a spout (1500) located above said column (1100) and positioned horizontally when in use, with a closed conduit (1510) extending from a first end zone to a second end zone, and adapted to receive water from said cartridge (1300) and dispense it to a user, and a control handle (1400) located above said column (1100) and above said spout (1500), and coupled to said cartridge (1300) to control the operation of said cartridge (1300). Said cartridge housing (1200) internally defines a conduit (1210) coupled at its inlet to the outlet of said cartridge (1300) and which opens directly into said conduit (1510) of said spout (1500) at said first end zone from below; the coupling between the conduit (1210) of said cartridge housing (1200) and the outlet of said cartridge (1300) is achieved directly by means of a water passage chamber (1220); said cartridge housing (1200) has an axis; said conduit (1210) of said cartridge housing (1200) is inclined relative to said axis by an angle between 0° and 30°.

The inventive puzzle game cube comprises: a central shaft assembly (110) with a centre, six central blocks (120) separately fixedly connected to the central shaft assembly (110) along different axial directions, a plurality of corner blocks (130) movably connected to the central shaft assembly (110) and the central blocks (120), a plurality of edge blocks (140) movably connected to the central shaft assembly (110) and the central blocks (120). Each of the central blocks (120) comprises: a bottom portion (121), a top portion (122) fixed to the bottom portion (121), an adjustment piece (126) being cylindrically-shaped, located in a room internally defined by the bottom portion (121) below and the top portion (122) above, and connected to the bottom portion (121) through a toothed coupling (127), a bottom magnet (124) being in contact with the adjustment piece (126) in a lower region thereof, a connected element (123) fixed to the central shaft assembly (110), arranged along an axial direction and passing through a hole in the adjustment piece (126) and a hole in the bottom portion (121), a top magnet (125) being in contact with a head of the connected element (123) in an upper region thereof remote from the central shaft assembly (110). The bottom magnet (124) and the top magnet (125) are oriented so that they repulse each other causing an axial force between the adjustment piece (126) and the bottom portion (121) so that the toothed coupling (127) is maintained during use of the puzzle game cube (100). The magnitude of the axial force depends on an axial distance between the bottom portion (121) and the adjustment piece (126) according to a first function; by changing a rotation angle of the adjustment piece (126) with respect to the bottom portion (121) said axial distance and said axial force are adjusted; said axial distance depends on the rotation angle of the adjustment piece (126) according to a second function.

The system (100) may be used for managing soilless cultivations in a smart way and comprises at least: a basin (110) configured to carry plants (115), placed in particular in pots (112) or on a slab (113), and plant substrate (116), contained in particular in the pots (112) or the slab (113), and to collect any drainage solution (114), in particular from the pots (112) or the slab (113), a base (120) configured to support the basin (110), at least one weight sensor (130A, 130B) configured to detect weight of the basin (110) with plants (115), substrate (116) and any drainage solution (114), a temperature sensor (142) configured to measure air temperature above the basin (110), a humidity sensor (144) configured to measure air humidity above the basin (110), a radiation sensor (146) configured to measure global radiation above the basin (110), possibly a wind sensor (148) configured to measure wind speed above the basin (110), a drainage valve (170) configured to discharge drainage solution (114) from the basin (110), possibly an irrigation valve (180) configured to irrigate the plants (115) in the basin (110), and a controller (190), comprising in particular an loT device; the controller (190) is coupled to the sensors as well as to the drainage valve (170) and the irrigation valve (180), and is configured to control the valves based on data from the sensor. Such system is able to calculate automatically the current values of several important agronomic parameters as well as to predict for example crop biomass, crop evapotranspiration, crop growth and crop coefficient through one or more Dynamic Bayesian Networks as well as to measure pH and EC of the drainage solution, which is important for optimizing the fertigation in the soilless systems.
