Photosynthesis -The importance of Illumination/Light

Why do Plants need Photosynthesis? All living things need energy to grow and reproduce. As for plants, they use cellular respiration to produce Adenosine Triphosphate (ATP). ATP is the energy-carrying molecule found in the cells of all living things. This respiration process needs glucose thus photosynthesis. Just like humans eat food to survive, plants make their own “food” through photosynthesis. Moreover, carbohydrates are also needed by the plant to build plant cell structures, like the cellulose cell wall. How does photosynthesis work? In the simplest explanation, it is a process where plants use light, water, and carbon dioxide to make glucose to survive. The complex explanation is that plants take in and use carbon dioxide through tiny holes in a plant’s leaves, flowers, branches, stems, and roots. Water is then absorbed by the roots to make the plant’s food with the presence of lights. You might be wondering by now; How does a plant take carbon dioxide and water to generate food? This is when the light comes in. The energy from light causes a chemical reaction that breaks down carbon dioxide and water to make sugar (glucose) and oxygen. The sugar is then broken down into energy that can be used for the plant’s growth. The oxygen that

What am I growing?

I was at friends gathering a few days back and the topic of discussion when into urban gardening. Had a great discussion sharing our experience in gardening in an apartment. Most of them tried growing flowers types like orchid and hibiscus. When I mentioned I mainly only grow edibles, it seems like I’m one of the minority. Some of them did try growing herbs but not vegetables like Lettuce and Xiao Bai Chai. As I thought it will be a good time for me to start a post to list the type of edibles I had tried growing and hopefully extend the list as I progress. Will list the easiest to grow to the most difficult, at least in my context using mainly Hydroponics.

Hydroponics System – EBB, DWC, NFT?

Starting your indoor farming using hydroponics and considering which hydroponics system is best suitable for your case? In this article, I'll be discussing the most common hydroponics system in use today and hopefully, you can use the information to decide the best system for yourself.The 7 SystemsLet's start the list from beginners to expert level.  I'll share my experience on each of these system and any recommendations using them. We can break these systems down to 3 main topics; 1) Is it a circulating or non-circulation system.  2) Is it possible to build it yourself or better to get it off-the-shelf from manufacturer.  3) How much time needed to maintain the system weekly. KRATKY SYSTEM - The idol proofIt is the only system in this list that allow you to grow without any moving parts that need electricity. It can be a 100% "hands off" system if you choose the right crops to grow. This system was first research and recommended by Dr. Bernard A. kratky from University of Hawaii at Manoa, hence named Kratky System. Dr. Kratky published a whitepaper on this topic in 2010 and has made it available publicly.  In this system, we fill the bucket/reservoir with nutrient water to the top touching the net pot holding the

Hydroponics – What is it?

Hydroponics is a subset of hydroculture, the method of growing plants without soil, using mineral nutrient solutions in a water solvent. The nutrients in hydroponics can come from an array of different sources; including byproduct from fish waste, duck manure, or normal nutrients. - wikipediaA Brief history of HydroponicsAncient examples of humans adopting technique of hydrocultureHanging Gardens of Babylon created in  3rd Century BC was the first of the seven ‘wonders’ of the world that used up 8,200 gallons of water a day. There are trees and plants in small man-created fields constructed on top of roofed colonnades which gave an impression of plants suspending in mid-air.An illustration of the gardens by the 16th century Dutch artist Martin HeemskerckAztecs and Chinese developed a similar system of floating gardens. In Aztec, their engineers created “floating” gardens using rafts anchored to the bottom of the lake, or to a strong tree. On these rafts, they piled dirt and muds to plant seeds to grow chilli peppers, corn, tomatoes, beans, and squash. These raft garden became extensive gardens reaching up to 22,000 acres across the surface of the lake. Marco Polo discovered similar floating gardens during his exploration of China in 13th centuries. A

Indoor Urban Farming. Is it worth the efforts?

Do you know anyone around you that are doing Urban farming today in their home? Have you ever wonder what are these urban farmers farming and why are they doing it? We’ll explore the “why” in another article but for now, let’s try to understand what we mean by Indoor Urban Farming. In order to do that, we need to explore 4 important concepts that enable us to be successful in Indoor Urban Farming. 1) What is an Urban Farming Movement? Urban Farming is when people are able to create food on unused land and space regardless it is a private or public housing estates. Urban Farms has also been created successfully in eateries, malls, schools, and offices. Many developing and developed countries worldwide are adopting urban farming in their city master plan mainly due to food security. Many non-government agencies are promoting the movement to grow your own food in suburban and urban cities because it provides fresh food, generates employment, recycles urban wastes, creates greenbelts, and strengthens cities’ resilience to climate change. 2) What is Indoor Farming? Indoor farming moves the creation of food from outdoor setup to an indoor environment. In Singapore, AVA is providing financial support to the farmer who is keen
