Claims

[Scope of utility model registration request]

A device main body 2 is formed into a long and shallow box shape and is arranged so that the bottom surface 1 is gently inclined in the longitudinal direction. a weir plate locking part 4; a weir 5 which is removably fitted between the pair of weir plate locking parts 4 and 4 and whose upper edge is lower in height than the side wall 3; a gap 6 for forming an underground flow formed between the lower edge of the weir and the bottom surface 1 in a fitted state;
A hydroponic cultivation device configured to supply a nutrient solution from upstream and allow the nutrient solution to flow over the weir 5, and also to allow the nutrient solution to flow downstream from the gap 6.
