Abstract: Vertical growing uses a plurality of shelves to support plants. The system provides nitrogen and light to help grow the plants placed on the shelves. The system also circulates air that is filtered and mixed with the nitrogen before being distributed to the plants. The filters can remove odors from the circulating air.

Abstract: An indicator assembly for attachment to a fishing rod, which assembly gives a positive, visual indication of a fish bite. The assembly, which may be semi-permanently or permanently mounted on a standard fishing rod, does not in its first, stored position, interfere with the normal use of the rod, being mounted thereon by means which permit conventional use of the rod. The assembly may be placed into use by merely unhooking a weight, which is carried by the mounting means and through which the fishing line is trained, permitting the weight to move, by gravity, from its first position, to a second, use position, spaced from the rod and whereby a portion of the fishing line is drawn away from the rod, the weight, in said second position, being shiftable in response to the bite of a fish on the line, to thereby visually signal said bite.

Abstract: A fish bit-indicator assembly adapted for use with an ordinary fishing rod and line comprises a weighted, slack ring device slidably attached to a stretch of the fishing line between guide ferrules of the rod and produces gravity-induced sagging of the line away from the rod in the absence of a fish bite when the rod is in a position tilted from vertical to create a slack section in the line along the rod. The slack ring holds the slack line section between the rod ferrules in tension and functions in response to even minute movement of the bait in any direction during a fish bite to sharply shift in elevation and thereby signal the bite, even when the line between the rod and the bait is swayed due to wind currents or water waves. A fishing tackle mounted rod support is provided for maintaining the rod in a desired tilted position when unattended in order to allow the slack ring to create a slack section in the line of optimum configuration for signaling the existence of a bite.
