Urban Farming

Extension of Crop Harvest Period Through Customised LED Light Recipes
The majority of the local indoor farmers grow crops that are harvested for their leaves. One way to increase the growth rate of such leafy greens is to provide a longer period of light. However, some of the crops grown, e.g., spinach, are long-day plants that flower when the light periods are longer than their critical day-length. While important to a plant’s life cycle, this vegetative to reproductive phase change is undesirable for farmers, not only because it shortens the harvest period hence reducing the yield, but also because it changes the taste profile. To tackle this problem, a light recipe that was able to suppress flowering was formulated. Plants grown under this light recipe showed a faster growth rate than those grown under flowering-suppressing short-day photoperiod. Moreover, they do not flower even when the light period has surpassed the critical day-length. Positive results were obtained when this light recipe was tested on spinach and arugula. This technology would work for other long-day crops, and it will be beneficial to indoor farmers who are interested to try it.
Living Plant Installations
Living Plant Installations is an integrally unique way of interacting with the vegetal environment. By converting plants into biological switches, we can activate lights, sounds, music, videos, and a myriad of other devices by touching plant leaves. Applications in smart cities, architecture, domotics, experiential marketing, events, and city spaces.   Video: https://drive.google.com/file/d/1Vwdb3Yj26arHi5omVH3CAxLHNL9qowCi/view?usp=sharing.
Novel Compounds that Keep Plant Fresh: Controlling Stomatal Aperture
Stomata are small pores present on the surface of leaves, which are opened or closed under the control of a pair of guard cells for gas exchange with the atmosphere. Through these pores, plants uptake the carbon dioxide necessary for photosynthesis and release water by transpiration, which enhances uptake of nutrients from the roots. Therefore, regulation of stomatal openings is essential for plant growth as well as survival in response to various environmental conditions. Through random screening of a chemical library of over 20,000 compounds, the technology provider has succeeded in finding new compounds that can control stomatal opening in plants. Analysis of stomatal closing compounds (SCLs) revealed that they inhibit the signaling components between the blue light receptor phototropin and the plasma membrane proton ATPase (PM H+ -ATPase), thus inhibiting light-induced activation of PM H+ -ATPase and leading to suppression of stomatal opening. Some of the compounds have shown to prevent leaves from drying up and suppress wilting when sprayed onto rose and oat leaves. The beauty of a chemistry-based approach instead of classical genetic techniques is that SCLs can be applied very easily to all plants. It also circumvents GMOs regulation.
Agricultural Sensors Powered by the Soil
Every day, the use of sensors in agriculture becomes more widespread. Sensors are used to measure climate conditions and soil parameters (such as humidity and pH), to predict crop yields and to identify potential dangers. Chemical batteries are the most common solution for the storage of energy in smart agriculture systems. They exhibit short lifetimes and must be replaced at least every 12 months under normal conditions. There is no reliable alternative to chemical storage in the market today. Solar panels have often been put forward as the sustainable power source of choice for remote sensing, however, they require constant maintenance resulting in high operating costs, and their connection to the sensors by cable is simply too expensive. Furthermore, all alternative solutions are either too expensive (wiring systems) or get easily deteriorated over time (piezoelectric) due to the harsh conditions, including dust, floods, and oxidation of internal components. This renders such solutions unreliable as power sources for periods of more than 2-3 months, making them unsuitable for remote monitoring in the majority of agricultural settings.  Our product is a ground-breaking sensing solution that completely eradicates the problem with powering agricultural sensors. 
A Decentralized Urban Farming IoT System
This Internet of Things (IoT) software architecture addresses a decentralized framework to provide the ability to exchange data between IoT devices autonomously without any centralized server. In recent years, the development of IoT applications has become increasingly complex. Thus, our technology addresses this problem by providing the ability to simplify the streaming of data to the IoT platforms over the web. The IoT platform is designed to assist the modern-day farmers in monitoring the entire farm seamlessly. It can be customized to suit each farm depending on the type of sensors, machine vision camera, cloud storage, etc. Equipped with detailed data tracking and analytics to provide the most accurate growth process from start to finish. This design can be customized for other applications.
Vertical Farming System Optimises Growing of Pesticide-Free Vegetables in Urban Spaces
Conventional forms of agriculture can be land-, water-, energy- and greenhouse gas emission-intensive. With growing urban populations and potential disruptions to food supplies, food security has become a pressing issue which has resulted in growing interest to produce food in urban environments. A key challenge of urban agriculture or farming is the limited land availability in urban settings.  An agri-tech company has developed an innovative vertical farming system that simplifies the process of growing pesticide-free vegetables productively within the constraints of urban spaces. The utilisation of vertical spaces – such as unused or under-utilised spaces like rooftops – uses less space for more produce and enhances the amount of harvest by 70% per sq ft. Compared to conventional farming methods, this technology promises 3.5x more yield with 30% less human effort. 
Customisable LED Software for Use indoor Farming
By the year 2050, nearly 80% of the world earth’s estimate 9.8 billion population will reside in urban centers. In addition, factors such as climate change, limited arable land and pollution will make indoor farming an attractive option. Current technologies used in traditional farming will definitely be inadequate and for Singapore, it will be even more vital to achieve food security with limited resources.  The technology described herein consists of a software and a horticultural LED system to target two main concerns of urban farming - operation cost and crop’s yield. The technology allows remotely control of all light's characteristics, including spectrum, photoperiod and intensity depending on the types of crops. This analytics can result in optimizing energy costs and also improving crop’s yield. This feature will be useful for farmers new to LED lighting. In addition, farmers can also use this technology to forumate their own “light” recipe to optimise the growth rate of their crops. The technology provider is seeking for collaboration from industry partners to commercialise this technology.

The technology and products are IP protected which serves as the basis to endless seed varieties for specific needs from clients from food companies.  
Innovative Dual Function Soil Moisturizer
Soils which are exposed to iterative wetting and drying in a tropical region, such as Singapore, are prone to develop hydrophobic coatings on the soil particles which results in hardness and water repellence. This condition limits the rate and capacity of water absorption, which leads to poor infiltration and water retention in soil. In these circumstances, water has tendency to either evaporate or run off instead of infiltrating into the soil, resulting in poor irrigation efficacy and water wastage. This problem can be further compounded by sloping terrain such as on mounds and on hillsides, where water is more likely to run off. These terrain will dry out quickly and requires additional irrigation, while the runoff collects in lower areas, creating wet spots that contribute to promoting soil compaction and encourage disease. Such phenomenon is detrimental to plant growth. A new formulation composed of surfactants and super-absorbent polymer dispersions, RetenSol, is createdto promote both soil wetting and moisture retention.The technology has been tested for a range of plant species and shown to improve the long-term water availability, serving as a mini water reservoir. During irrigation, the innovative formulation is able touptake large amount of water, and the locked water moleculeswould not easily evaporate and serve as a reservior that will release water during drought stress.
