A system (1) for growing produce (3) in greenhouses. The system (1) includes at least one greenhouse (5) for housing the produce (3) to be grown, the at least one greenhouse (5) being positioned, shaped and sized for receiving direct sun rays (7d). The system (1) also includes at least one reflector assembly (11) proximate to the at least one greenhouse (5) and being positioned, shaped and sized for redirecting indirect sun rays (7i) by-passing the least one greenhouse (5), towards at least one targeted area (13) within the at least one greenhouse (5), so as to provide said at least one greenhouse (5) with assisted complementary solar energy.
