The greenhouse dome is constructed of identical rhombic surfaces on identical struts and is mounted on a base with vertical surfaces and can be both land and water-based. In the water-based embodiment, the shell (51) rests on a block of foamed plastic (42) with a central through-pipe (46) for ventilation and serving as a point of attachment when the entire arrangement is lifted up out of the water by a crane. For construction on land, there are vertical pipes (47,48) for insertion of supporting legs. Air circulation (53,46,49,52,50) can be regulated by a damper (55). The water is collected in a reservoir (54) on the sheet (43) enclosing the bottom of the floating body (42). Nutrient solution is circulated from the bottom (58) of the cultivation troughs (59) with a pump (57) to the highest point (60) of the troughs. |
