Vertical Crop Cultivation System with Nutrient, Light, Air and Audio Control

The problem

In indoor and vertical farming, maintaining the correct water temperature for the nutrient solution is difficult when outside air temperatures fluctuate. Heating or cooling the liquid requires additional equipment that consumes energy and raises operating costs. Managing multiple environmental variables—light, nutrients, humidity, air composition, and even sound—at the same time across several growing layers adds complexity. Without coordinated control, conditions may drift away from what the specific crop needs during different growth stages, leading to uneven yields.

The solution

This system combines six main units to manage the growing environment inside a single enclosed space.

1. A building facility (10) surrounds the cultivation space. Inside, at least one layer frame (11) holds plural cultivation beds (12) in a layered configuration. Personnel enter through a personnel’s entrance (13) covered by a channel gate (14).
2. A nutrient solution supply unit (20) includes at least one reservoir (21) embedded under the earth’s surface. A nutrient solution pumping device (22) moves liquid through nutrient solution transmission & distribution pipelines (23) to each bed. The soil barrier reduces outside temperature interference, helping avoid freezing or overheating.
3. A light illuminating unit (30) places a photoelectricity mould group (31) at each cultivation bed to generate a preset light source after being powered.
4. An air-conditioning unit (40) uses at least one water Lian (water curtain) (41) communicating with the cultivation space. Supply equipment (42) connects to the water curtains and feeds at least one bubble mould group (43), which can include oxygen bubble generators (431), carbon dioxide bubble generators (432), or ozone bubbles generators (433).
5. An audio frequency adjust unit (50) places at least one loudspeaker (51) communicating with the cultivation space, driven by an audio player (52).
6. A control unit (60) connects electrically to the pump (22), photoelectric modules (31), bubble modules (43), and audio player (52), controlling whether they act.

Who it is for

• Commercial vertical farm operators looking to build enclosed facilities with layered beds and integrated climate, light, and nutrient management.
• Hydroponic equipment manufacturers seeking a complete system design that incorporates underground reservoirs and bubble-based air conditioning to offer buyers.
• Agricultural technology brands expanding their catalog with controlled-environment agriculture setups that include audio frequency adjustment.
• Wholesalers supplying greenhouse builders who need a documented multi-unit architecture to source components like water curtains, bubble generators, and layer frames.

How it works

The main parts

Operating steps

1. Prepare the reservoir: The nutrient solution is held in the underground reservoir (21), where soil insulation maintains its temperature.
2. Distribute nutrients: The control unit (60) activates the nutrient solution pumping (22) to send liquid through the pipelines (23) to the cultivation beds (12).
3. Illuminate: The control unit powers the photoelectricity mould groups (31) to provide the preset light source to the crops (70).
4. Condition the air: The supply equipment (42) drives the water curtains (41) and bubble mould groups (43). Depending on the setup, oxygen (431), carbon dioxide (432), or ozone (433) bubbles are introduced to adjust the air composition.
5. Adjust audio: The control unit signals the audio player (52) to drive the loudspeakers (51), introducing sound wave vibration frequencies into the space.
6. Coordinate: The control unit adjusts whether these components act based on the actual growth state of the planted crops.

Applications

Commercial leafy green production

Leafy greens require steady nutrient temperatures and consistent light. Operators use this system to grow crops on layered beds inside the building facility, relying on the underground reservoir to prevent the nutrient solution from overheating during warm seasons without adding external chillers.

Research and agricultural testing

Researchers studying plant responses to varied atmospheres use the bubble generators to introduce specific ratios of oxygen, carbon dioxide, or ozone. The control unit allows them to turn individual modules on or off to observe how the crops react to changes in air composition and sound wave vibration frequency.

Urban warehouse farming

When converting urban warehouses into farms, space utilization is critical. The tiered layer frames hold plural cultivation beds vertically, making effective use of the terrace space inside the enclosed building facility while personnel access the rows through the gated entrances.

Seedling propagation nurseries

Nurseries propagating seedlings need stable water temperatures to avoid shocking young roots. The soil barrier around the embedded reservoir keeps the nutrient solution within a suitable range, reducing the risk of freezing in colder months or overheating when outdoor temperatures rise.

Specialty herb cultivation

Herbs grown for culinary or aromatic purposes benefit from controlled environmental adjustments. Growers use the audio frequency adjust unit and the light illuminating unit together, letting the control unit manage both based on the practical growth conditions of the specific herbs.

Where it is less suitable

• Open-field agriculture - the system relies on an enclosed building facility and underground reservoirs, making it unsuitable for open fields.
• Large-scale grain farming - grains like wheat or corn require vast horizontal acreage rather than layered indoor beds.
• Low-budget hobby setups - integrating water curtains, multiple bubble generators, photoelectric modules, and a central control unit involves more infrastructure than a simple home grow tent.
