Mari's Gardens Organic lettuce farming

Mari's Gardens features a large selection of plants and produce on 18 acres. They specialize in organic farming and are the largest aquaponics farm in Hawaii. Aquaponics combines growing plants hydroponically, and growing fish through aquaculture. On their farm they produce tilapia and Chinese catfish. The water from the fish tanks they use to produce high-quality Manoa lettuce, green oak leaf, red oak leaf. Apart from lettuce, they also produce mizuna, spinach, tomatoes, cucumbers and lychees. Their method of farming is sustainable, organic and are food safety certified.

Tipburn Challenge

Manoa lettuce is a type of mini lettuce that has a uniform, compact, upright shape and is very popular in Hawaii. The manoa lettuce is locally grown in Hawaii. Consumers use manoa lettuce in place of any other lettuce, such as romaine and butter lettuce. Manoa lettuce is popular with the local consumers. The variety is susceptible to tipburn. Tipburn is the breakdown of leaf tissue and results in brown dried out spots on the leaves. Tipburn is a big problem as it is reducing the sellable product by 25%.

Tipburn also reduces growth results in a smaller crop. A problem in Hawaii is that the irrigation water is warm 23.9 °C (75 °F). In the morning and in the afternoon, temperatures can go up to 26 °C (79 °F). Mari’s Gardens goal was to improve the production quality by growing larger, sturdier crops and eliminating tipburn.

Ultrafine bubble Benefits

Maris Garden opted for an agriGaLF. They installed the agriGaLF onto a 2.6 m3 (700 gallon) nutrient feed tank. The nutrient feed tank connects to a hydroponic rafts gutter system of 15,000 heads of lettuce. The nutrient feed water recirculates all the time in this closed loop system.

Maris Garden started the trail recipe running the ultrafine bubble generator in intervals of 2 minutes on and 20 minutes off. The result was an increase of DO levels from 6.5 to 7.8 mg/liter. Higher DO levels reduced the amount of tipburn problems. After 2 weeks they increased the operation time from 2 minute to 10-minute intervals. Now the DO levels were up to 8.43 mg/liter.

Upon achieving these DO levels, the tipburn problems disappeared. Increasing their sellable product immediately by 25%. On top of that Mari's Gardens was able to grow lettuce with a higher EC which resulted in a firmer crop. In consideration of these results, the agriGaLF can be a lucrative solution for many greenhouse operations. Especially those with warm irrigation water and low DO levels.

"I am proud to grow organic vegetables, including Manoa lettuce. The agriGaLF improves the quality of our produce greatly" — Fred Lau, owner of Mari's Gardens

Young plants growing with turbiti nanobubbles for better results

Acniti partner Foreport in Taiwan conducted a vegetables young plant cultivation trial, irrigating with oxygen nanobubbles. The nanobubble irrigation water had a DO of 20 ppm versus the regular irrigation water which had 6.8 ppm. After 6 weeks results were taken it was concluded that the crop treated with nanobubbles was 25-30% heavier. The nanobubble irrigated crop also had a better developed root system which will lead to less root diseases and better survival rates during hot summers.

How to measure fine bubbles?

Nanobubbles can be measured by the same technology as measuring small particles. You can measure bubbles by camera (count pixel size) or laser (count blackout time), also as a simple method to know number index, you can refer information of turbidity. When you measure UFB, most common way is to analyze Brownian Motion.

The zeta-potential important stuff for nanobubbles

The electrical properties of gas bubbles are important in determining the interaction of nano-bubbles if and when they merge together and how they interact with other materials such as solid particles or oil droplets. Knowledge about this helps application development in for example, protein skimmers, froth flotation, food processing, washing surfaces and purification.

Nanobubbles are useful in accelerating the metabolism of living organisms, but the mechanism is not yet well understood. In a study, they investigated the production of reactive oxygen species (ROS) by Nano Bubbles and the effect on seed germination. The conclusion of the study was seeds in nanobubble water had a higher germination rate than all those submerged in the different other conventional used solutions.

葉先焼けのない魅力的なレタスを栽培する

Manoa lettuce is a lettuce variety susceptible to tipburn. Tipburn is the drying and dying of leaf tissue along the edges of the leaf. During a test at a grower in Hawaii it was shown that by increasing the DO levels and adding ultrafine bubbles, reduction of tipburn is realized and quality and production improvements are made.

Washing of surfaces and laundry is one of the promising areas were ultrafine bubbles can make a difference in the application. Reducing the amount of detergent, has a positive effect by reducing pollution, washing laundry without detergent, would greatly benefit the environment. Ultrafine bubbles can lower the surface tension of water, the large amounts of oxygen molecules in bubbles charge the water negative.

Bubbles are all around us, in our foods, beer, pop drinks bread and cheese, but also in the bricks of our house. Bubbles are gas-filled cavities in water, the lifetime of a bubble is short at most a few minutes, only ultra-fine bubbles are stable for longer periods like months, that is making them very special and that enables us to change the properties of water.
