The modular germinating apparatus provides a plurality of rods, each with an extendable insert whereby total length of the rod and insert is adjustable, the adjusted length selectively maintained by dual, outward pressed lock pins. Rods are positioned as chosen both horizontally and vertically between given objects, such as window sills. A plurality of planters with planter inserts is hung as chosen from the rods with extendable inserts, thereby providing for germinating a multitude of plants simultaneously, with great space efficiency. Each insert provides a plurality of individual compartments, each compartment having drain holes for draining excess liquids from the compartments to the planter below, thereby maintaining optimal germinating environments.
