PURPOSE: Provided is a transparent bulkhead for greenhouse to have good effects economically by separating the transparent bulkhead if necessary and to save the cost and protect resources by using the recycled waste synthetic resin materials as the transparent bulkhead materials. CONSTITUTION: In the green house(1) comprising the multiple bending frames(3) formed in a gap and on one side, the transparent bulkhead(2) for greenhouse are inserted and mounted between the bending frames(3) and have the multiple flexing parts to control the transmission range of light. The transparent bulkhead(2) for greenhouse is composed of synthetic resin materials or glass materials. The flexing parts have the multiple prominent convex spheres formed on one side thereof.
