PURPOSE:To obtain the subject apparatus having small number of lighting apparatus and hardly plugged up by reciprocating lighting apparatus located over the middle part of seedbed by a transferring means at a low speed along the seedbed and by ejecting nutritive solution to upper inside of a seedbed panel from ejecting holes of an ejecting hose between seedbeds. CONSTITUTION:A lighting apparatus 8 suspended by a rail part 5 is located between each seedbed 1 and an ejecting hose 23 having many ejecting holes is located inside of each seedbed 1. Insert holes 3 of each panel 2 in the seedbed 1 are inserted rock wool, etc., in which seedlings are planted. The lighting apparatus 8 is reciprocated at a low speed along the panel and plants are irradiated. Nutritive solution is ejected from ejecting holes of the ejecting hose 23 to upper inside of the panel, then the nutritive solution is flowed down along the panel. |
