To provide a plant raising apparatus increasing absorption ratio by the plants and promoting raising of plants through arranging a mixed light source section mixed in good proportion with red light emitting diode and blue light emitting diode each effective for photosynthesis acting.

This plant raising apparatus 1 by the mixed light source of red LED and blue LED forms a transparent cylindrical body 3 for implanting seeds or seedlings and other plants 6 in soil 5 contained on a foundation 2 and covering the whole, and vent holes 7 on the transparent cylindrical body 3. A water supply hole 8 and a shower section 9 for scattering water and a growth agent from the water supply hole to the inside of the transparent cylindrical body are each formed on the cover 4 of the transparent cylindrical body 3. The LED light source has the mixed light source section 10 which forms inside the cover 4 a panel 13 established in the proportion of about 6:4 of much of 3cd red LED 11 and 1cd blue LED 12 each simultaneously emitting, and a switch 14, a timer 15 which fixes irradiation time and a power source section 16.
