Systems and methods for raising a cart in a modular grow tower

A system for raising a cart in a modular grow tower assembly, comprising:

• a modular grow tower assembly including a plurality of body frames and a plurality of lift frames, the body frames configured to support a plurality of carts moving along a path from a top end to a bottom end of the modular grow tower assembly;
• a harvest frame positioned adjacent to one of the lift frames, the harvest frame including a rectangular base frame, vertical supports, and a top support;
• a raising lift mechanism configured to pull a cart from the modular grow tower assembly into the harvest frame, the raising lift mechanism comprising a base frame, a rail with fork members, and rollers, wherein the rail is rotatably and longitudinally movable between an extended position and a retracted position, and the fork members are configured to engage wheels of the cart;
• and
• wherein the raising lift mechanism is further configured to move vertically within the harvest frame to position the cart for subsequent harvesting, sanitizing, seeding, and reinsertion into the modular grow tower assembly.
