Autonomous plant growing systems

1. A system comprising:

a camera;

one or more light sources; and

a controller programmed to:

receive an image of one or more plants from the camera;

apply a segmentation algorithm to produce a binary image from the image;

apply a thresholding algorithm to classify the one or more plants within the binary image as being in one or several stages of plant life; and

control operation of the one or more light sources based on a classified stage of plant life including controlling operation of the one or more light sources to:

expose the one or more plants to darkness for 36 hours to induce a transition to a flowering stage; and

expose the one or more plants to one or more selected from the group consisting of: a high ratio of at least 75% red light prior to the darkness and a low ratio of 25% or less red light after the darkness.

2. The system of claim 1 , wherein the controller is further programmed to control operation of the one or more light sources to apply more blue light than red light during an early stage of plant life selected from the group consisting of: planted, sprouted, and growing.

3. The system of claim 2 , wherein the blue light includes a wavelength of about 450 nm.

4. The system of claim 1 , wherein the controller is further programmed to control operation of the one or more light sources to apply more red light than blue light during an late stage of plant life selected from the group consisting of: flowering, fruiting, and ripe.

5. The system of claim 4 , wherein the red light includes a wavelength of about 650 nm.

6. The system of claim 1 , wherein the controller is programmed to control the one or more light sources to generate a high ratio of at least 75% red light prior to the darkness.

7. The system of claim 1 , wherein the controller is programmed to control the one or more light sources to generate a low ratio of 25% or less red light after the darkness.

8. The system of claim 1 , wherein the one or more light sources include one or more blue LEDs and one or more red LEDs.

9. The system of claim 1 , wherein the segmentation algorithm is a binary segmentation algorithm.

10. The system of claim 9 , wherein the binary segmentation algorithm is Otsu's method.

11. The system of claim 9 , wherein the binary segmentation algorithm is a watershed method.

12. The system of claim 1 , further comprising:

one or more pumps adapted and configured to apply one or more fluids to the one or more plants;

wherein the controller is further programmed to control one or more pumps based on the classified stage of plant life.

13. The system of claim 12 , further comprising:

a flood tray in communication with the one or more pumps, the flood tray adapted and configured to receive the one or more plants and the one or more fluids.

14. The system of claim 1 , wherein the controller is further programmed to:

send alerts to a user.

15. The system of claim 14 , wherein the alerts relate to needed user interventions.

16. The system of claim 14 , wherein the alerts include alerts regarding low fluid levels.

17. The system of claim 14 , wherein the alerts are directed to a user's smartphone.

18. A computer-implemented method of growing plants, the computer-implemented comprising:

receiving an image of one or more plants from a camera;

applying a segmentation algorithm to produce a binary image from the image;

applying a thresholding algorithm to classify the one or more plants within the binary image as being in one or several stages of plant life; and

controlling operation of one or more light sources based on a classified stage of plant life including controlling operation of the one or more light sources to:

expose the plant to darkness for 36 hours to induce a transition to a flowering stage; and

expose the one or more plants to one or more selected from the group consisting of: a high ratio of at least 75% red light prior to the darkness and a low ratio of 25% or less red light after the darkness.
