A spiral growing system is configured to be housed in a vertically elongated silo growth chamber to grow an agricultural crop. The spiral growing system broadly includes a spiral growing assembly and a movable crop support. The spiral growing assembly extends along an assembly length to at least partly define a spiral growing space to receive and feed the agricultural crop therein. The spiral growing assembly includes a continuous track and a feeding system. The track extends continuously along the assembly length and is configured to direct the agricultural crop along a generally downward spiral path. The movable crop support is operably supported by the track and is configured to be advanced downwardly along the assembly length to thereby direct the agricultural crop through the growing space with the feeding system providing direct root application of a supply of water and/or nutrients to the agricultural crop along the track.
