Root growth optimization method
A farming method may be shown and described. In an exemplary embodiment, plants may begin in a germination phase. Next, plants are brought to a nursery for a period of time before optionally being transplanted to one or more subsequent nurseries. Plants in the nurseries may be stacked vertically in trays. During the nursery phase, root growth may be optimized. Finally, plants are transplanted to a greenhouse where they may grow until they are ready for harvest. In an exemplary embodiment, the nursery phases may be vertical farms while the greenhouse phase may be a traditional, hydroponic, or other type of farm which may receive sunlight. AI may be implemented to optimize environmental conditions and robotics may be used to harvest the plants.
1. A method for farming plants, comprising:
planting a plurality of plants in one or more trays, and placing the trays in a nursery;
in the nursery, placing each tray above a surface of water, wherein a root zone substrate of each of the plants contacts the water during initial placement;
transplanting the plants to a modified planting tray, wherein in the modified planting tray the root zone substrate is suspended over the water;
encapsulating a plurality of roots in the root zone substrate in a protected chamber, wherein the protected chamber comprises a microclimate and is configured to guide root growth outside of the root zone substrate, and wherein the roots inside the protected chamber are protected from air pruning;
after placing the trays above water, and after a plurality of roots begin to develop from the root zone substrate, separating the root zone substrate from the water, creating a gap between the root zone substrate and the water, wherein the root zone substrate is still at least partially or periodically submerged in the water after separating the root zone substrate from the water;
monitoring a size of the roots of the plants, and continuously reducing a water level to increase the gap as the roots grow;
after the roots reach a predetermined size, moving the plants to a greenhouse where the roots of the plants are directly submerged in a stream or body of water.
2. The method for farming plants of claim 1 , wherein the plants are arranged in a vertical farm in the nursery and in a horizontal farm in the greenhouse.
3. The method for farming plants of claim 1 , wherein the plants in the greenhouse receive lighting from at least natural sunlight.
4. The method for farming plants of claim 1 , wherein the trays further comprise an open bottom, such that the roots can grow in a direction towards the water without obstruction.
5. The method for farming plants of claim 1 , further comprising
storing plant historical data comprising the monitored size of the roots along with a plant growth time and
identifying an optimal time to move the plants from the nursery to the greenhouse based on the plant historical data.
6. The method for farming plants of claim 1 , wherein the plants are placed in one or more rafts immediately prior to the greenhouse, and the rafts are placed in the greenhouse.
7. The method for farming plants of claim 1 , wherein the nursery phase comprises a nutrient film technique, ebb and flow, or deep-water culture.
8. The method for farming plants of claim 1 , further comprising at least one additional nursery phase, wherein the additional nursery phase comprises a different watering system than the nursery.
9. The method for farming plants of claim 1 , further comprising monitoring plant size; identifying an optimized plant density based on the plant size; and arranging the plurality of plants according to the optimized plant density.
10. The method for farming plants of claim 1 , wherein the nursery comprises a first nursery phase and a second nursery phase, and wherein the first nursery phase comprises an ebb and flow watering technique and the second nursery phase comprises a nutrient film technique.
11. The method for farming plants of claim 1 , further comprising harvesting the plants.
12. The method for farming plants of claim 1 , further comprising at least one additional nursery, wherein the trays are modified in the at least one additional nursery to remove a bottom portion of the tray such that the plant plugs directly face and contact the water, and such that the roots grow towards the water unobstructed.
