Water culture block

A water culture block comprising:

• a block body including a bottom plate and a plurality of side plates, each side plate being perpendicular to the bottom plate, the block body having an inner space formed therein, and the bottom plate comprising a plurality of drain holes;
• and
• an overflow partition zone comprising:
• a plurality of anti-interference column pipes upwardly extending from the bottom plate and respectively positioned above the plurality of drain holes, each of the plurality of anti-interference column pipes comprising a lower end connected to the bottom plate and an upper end opposing the lower end, and
• a plurality of overflow partition walls upwardly extending from the bottom plate, each of the plurality of overflow partition walls respectively connecting two adjacent ones of the plurality of anti-interference column pipes such that the plurality of overflow partition walls and the plurality of anti-interference column pipes together surround an overflow drain space in the overflow partition zone,
• wherein each of the plurality of anti-interference column pipes comprises an inner side opening in fluid communication with the overflow drain space to discharge a fluid overflowing in the block body through the inner side opening and a corresponding one of the plurality of drain holes, wherein the inner side opening continuously extends from the lower end to the upper end of each anti-interference column pipe to cause the fluid overflowing from the inner space into the overflow drain space to be discharged through the inner side openings and the drain holes,
• wherein the plurality of anti-interference column pipes comprise a first column pipe, a second column pipe, a third column pipe, and a fourth column pipe,
• wherein the first column pipe and the third column pipe are disposed diagonally to each other, and the inner side opening of the first column pipe and the inner side opening of the third column pipe face each other, and
• wherein the second column pipe and the fourth column pipe are disposed diagonally to each other, and the inner side opening of the second column pipe and the inner side opening of the fourth column pipe face each other.
