Growing systems may include a number of modular growing chambers adapted to be configured in a stacked arrangement with each growing chamber surrounding a corresponding portion of the plant. The grow chambers may be selectively added or removed during plant growth, such that different sections of the growing plant may be influenced differently using aeroponic, hydroponic or other growing techniques. The grow chamber stack may be portable and provided with integrated or independent lifting devices to assist an operator in adding or removing chambers from the stack. Three growing processes may be facilitated using such systems. These include a process for producing assorted product from a single plant for simultaneous harvest, a process for producing an extended harvest of a desired size product from a single plant, and a process for extending the productive life of a plant and provide for multiple, continued, and perpetual harvest.

A soil moisture sensor and a soil moisture sensing system are provided. The soil moisture sensor includes a double groove helical structure having grooves and formed from an insulator. The soil moisture sensor further includes at least a first electrode and a second electrode formed from one or more metals deposited at at least two different locations on the grooves. The soil moisture sensor also includes a processor for processing a soil moisture measurement signal based on a conductivity between the electrodes. The soil moisture sensor additionally includes a wireless transmitter for transmitting the soil moisture measurement signal to a remote location.

A combined PVC gardening profile includes a main profile. The main profile includes a main-profile base board; a main-profile outer bottom frame is disposed on a left side of the main-profile base board; a main-profile invisible groove is disposed in the main-profile outer bottom frame; a main-profile invisible trench is disposed on a bottom surface of the main-profile invisible groove; a main-profile strengthening rib is disposed on a right side surface of the main-profile outer bottom frame; a main-profile cambered plate is connected to a top right corner of the main-profile outer bottom frame; a main-profile fluorescent lamp groove is disposed on the main-profile cambered plate; a main-profile inner side board is disposed at a lower end of a right end edge of the main-profile cambered plate; and several main-profile fastening pin holes are provided at a right edge of the main-profile base board.

The present invention provides a longitudinally split immature tiller separated from a rhizome (LSITR), a cluster of multiple in vitro shoots (CMIT), a cluster of stem segments containing shoot primordia (CSSSP) and an in vitro tiller of Miscanthus x giganteus (Giant miscanthus), and their uses in propagating Miscanthus x giganteus (Giant miscanthus).

Apparatus, systems and methods are provided for crop stand optimization. In some embodiments a field is planted at a first population prescription determined based on a first data set including forecasted weather. A subsequently determined second population prescription is determined based on a second data set determined after planting, and the planted crop is thinned according to the second population prescription. In some embodiments the crop is selectively thinned to remove plants having a plant removal index below a threshold.

A soil testing device includes a housing and at least one sensor assembly rotatably connected to the housing. The at least one sensor assembly is configured to insert into soil and to output an electrical signal corresponding to a soil parameter to be displayed on a display unit. The at least one sensor assembly includes a rotating portion and a detecting rod, the rotating portion is connected with the detecting rod, and the rotating portion is disposed in the housing, the detecting rod extends out of the housing from an interior of the housing.
