1. A floatable plant cultivation device comprising:a plurality of floatable parts each having a first passage defined through a center thereof and a plurality of second passages located around the first passage and defined through the floatable part corresponding thereto; a plurality of connection members each having a plurality of engaging ends which are engaged with second passages of individual floatable parts, each engaging end connected to a distal end of one of extensions extending from an underside of each of the connection members, each engaging end including two lugs with a gap defined therebetween and each lug including a notch on an outside thereof, each second passage including a first flange extending inward from an inner periphery thereof so that the notches of the two lugs of each engaging end are engaged with the first flange, and a plurality of pots respectively engaged with the respective first passages, each pot having slots defined through a wall thereof. 2. The device as claimed in claim 1, wherein an annular groove is defined in an outer periphery of each of the pots and each first passage has a second flange extending inward from an inner periphery thereof, the second flange being engaged with the annular groove.3. The device as claimed in claim 2, wherein the outer periphery of each pot is a tapered outer periphery and each first passage includes an upper partition and a lower partition, each of the top and lower partitions having a tapered inner periphery, the second flange located at a conjunction of two respective narrow ends of the upper partition and the lower partition.4. The device as claimed in claim 1, wherein each pot includes a periphery that includes an upper portion with a plurality of slots defined therethrough, a close area and a lower portion with a plurality of slots defined therethrough, a porous bottom connected to the lower portion, a diameter of the close area being smaller than a diameter of the upper portion so as to form a shoulder portion which is engaged with an annular edge of the first passage define in a top surface of the floatable part.5. The device as claimed in claim 1, wherein each pot includes a periphery that includes an upper portion with a plurality of slots defined therethrough, a close area and a close lower portion, a bottom with a central hole being connected to the lower portion, a diameter of the close area being smaller than a diameter of the upper portion so as to form a shoulder portion which is engaged with an annular edge of the first passage define in a top surface of the floatable part.6. The device as claimed in claim 1, wherein each pot includes a periphery that includes an upper portion with a plurality of slots defined therethrough and a close lower portion, a bottom with a central hole being connected to the lower portion, a diameter of the close lower portion being smaller than a diameter of the upper portion so as to form a shoulder portion which is engaged with an annular edge of the first passage define in a top surface of the floatable part.7. The device as claimed in claim 1 further comprising a lip extending outward from a top edge of the top portion of the pot.8. The device as claimed in claim 1, wherein each of the floatable parts has a hollow interior.9. The device as claimed in claim 1, wherein each of the connection members composed of at least two plates which are connected with each other, each one of the at least two plates having one engaging end.
