Abstract

Systems, apparatuses and methods for growing marijuana plants, particularly for regulated purposes, for example medical purposes or in some jurisdictions recreational purposes, have automated subsystems with sensors to provide feedback information about system, apparatus and plant growth parameters to one or more controllers so that the one or more controllers can alter one or more parameters to provide optimal conditions for the growing and harvesting of the marijuana plants. In particular aspects, the systems, apparatuses and methods provide for control of odors produced during the growing of marijuana, root management of the marijuana plants and control over important levels of chemicals provided to the plants, for example enzymes and flavor additives.

Claim(s)

1. An apparatus for growing marijuana plants comprising: a growth chamber containing a climate controlled micro-climate under negative air pressure; at least one marijuana plant support structure situated in the growth chamber for supporting a marijuana plant whereby roots of the marijuana plant are exposed to air in the growth chamber; a water management system in fluid communication with the plant support structure for delivering water and other chemical components besides water to at least the roots of the marijuana plant; at least one sensor for sensing at least one parameter of the growth chamber, water management system or marijuana plant, the at least one sensor comprising an optical device for detecting size and/or color of at least a portion of the marijuana plant, a sensor for sensing peroxide level in the water, a sensor for sensing nutrient level in the water, a sensor for sensing flavor additive level in the water and a sensor for sensing a marker dye level in the water; and, a controller in electronic communication with the at least one sensor and one or more of the growth chamber and water management system, the controller for controlling the growth chamber, water management system or both in response to a signal from the at least one sensor.;
6. An apparatus for growing marijuana plants comprising: a growth chamber containing a climate controlled micro climate under negative air pressure; at least one marijuana plant support structure situated in the growth chamber, the plant support structure configured to support a marijuana plant whereby roots of the marijuana plant are exposed to air in the growth chamber; a water management system in fluid communication with the plant support structure for delivering water and other chemical components besides water to at least the roots of the marijuana plant; at least one sensor for sensing at least one parameter of the growth chamber, water management system or marijuana plant, the at least one sensor comprising an optical device for detecting size and/or color of at least a portion of the marijuana plant, wherein the at least one sensor further comprises a colorimeter for measuring levels of one or more of the other chemical components in the water management system; and a controller in electronic communication with the at least one sensor and one or more of the growth chamber and water management system, the controller for controlling the growth chamber water management system or both in response to a signal from the at least one sensor.
