Learn About Hydroponic Management (Hydroponics II)
Hydroponic Management course online (Hydroponics II) offers an even more in – depth online course than Hydroponics I, where we take a closer look at a few plant species in particular.
Hydroponic grower trials attempt to simulate conditions under which a crop might be grown commercially, but on a much smaller, and less costly scale.
They often compare the success of growing a number of different plants, or groups of plants. There are many different variables that can affect the success or failure of a hydroponic crop. These fall into different categories, including:
Type of system
Nutrition supplied
Water supplied
Plant cultivar being grown
Environmental conditions (eg. Temperature, light, air quality)
Exposure to pest and disease
Cultural Management (eg. Pruning, spacing, harvest time, etc).
Understanding How a Plant Grows in Hydroponics: Roots, Stems, Leaves, Reproductive Parts
Controlling the Growing Environment: Light levels, Air temperatures, Root zone temperature, Relative humidity and vapour pressure deficit, Water, Plant nutrients, Heating and ventilation systems, Thermal screens, Blackout, Shading, Lighting equipment, Link to external weather station, Ability of systems to record data
Controlling Plant Growth: Stopping, Spacing, Disbudding, Trimming, Training, Growth control – Chemical and cultural for ornamental crops, Pest, disease and disorder control: (chemical and cultural), Cultural controls
Intercropping

Excerpt From The Course
How to prepare salad mixes from harvested hydroponic produceChlorination levels and washing of produce Salad greens should be harvested early in the morning to obtain turgid tissue (with a high water content). Leafy greens harvested during warm greenhouse conditions are often slightly wilted at the time of harvest and will have a greatly reduced shelf life. It is important that where-ever greens such as herbs, lettuce etc. are to be cut, that a very sharp knife is used for this purpose (i.e sharpened on a regular basis and cleaned after each day’s harvest). A sharp blade minimises cell damage and the resulting oxidation of cellular fluids after harvest. A lettuce cut by a sharp knife with a slicing motion will have a storage life approximately twice that of a lettuce but with a chopping action. Shelf life of lettuce is much less if a dull knife is used rather than a sharp one. After harvesting into clean field bins, the salad greens should be cooled to below 5 C before processing into salad mixes. In cases where a cooler is not available, the harvested product should be immediately placed into cool water – adding ice cubes, cooler packs or crushed ice to the washing water will serve this purpose. Most salad greens, apart from those which can suffer chilling injury, such as basil, should be given this treatment. Care needs to be taken when cut basil is to be part of a salad mix as it is temperature sensitive and should not be washed or stored below 10 C, as it will discolour and go black once packaged. Basil and cilantro should not be incorporated into salad mixes that will be stored under refrigeration (below 7 – 10 C) as it will blacken in the salad mix. Salad greens should be washed in cool water as soon as possible after harvest. This water needs to be chlorinated to kill the microbial life on the leaf surfaces which would later cause fungal growth and tissue discoloration. Washing the cut product removes sugar and other nutrients at the cut surfaces that favour microbial growth and oxidation. Water should be chlorinated with 0.2 ml per litre of chlorine. Any leaves which need to be further cut should be done so before washing. After the chlorinated wash (at below 5C), the leaves should be rinsed twice in fresh, clean, chilled water and water in wash tubs replaced frequently. After washing and rinsing, any free moisture on the leaves must be removed – centrifugation is generally used, although air blast driers can also be used for this purpose. Many smaller salad processors use `salad spinners’ either hand or electric powered to remove the moisture from the leaves. Excess moisture left on the leaf surface will result in condensation within the salad pack and the growth of moulds, bacteria and other problems during storage. After drying, mixes can be combined and packaged into bags or punnets and cooled to 2 – 3 C,. The faster the product is cooled down to a storage temperature of 2 – 3 C, the longer the shelf life will be. Prepacked salads typically only last 2 – 3 days at 25 C, but can last in excess of 8 days at 1 – 3 C. Packaged product should not be shipped or transported until it has reached the required 1 – 3 C and delivered under refrigeration where ever possible.
Assessment
Assessment is based on a combination of completing all assignments and sitting for a final short one and a half hour exam, in your own location.
If you don’t cope well with exams then you may elect to undertake a project instead. This is a popular option.
In addition, most modules have a Set Task at the end of each lesson placed before the assignment. This is an opportunity to undertake practical work to help you acquire knowledge and skills and practical experience. This ADL feature is an added bonus not found at most online schools. Set Tasks are not required for assessment.
Some courses also have optional Self-Tests which are available on our online learning platform. These are not available by correspondence or by USB, and do not form part of your overall grade.
How our courses work
Choose Your Learning Method You choose how you would like to receive your course material, i.e., Online, USB or Correspondence. The choice is yours. You may also work on online or offline.
Tutor Allocation Every student is assigned their own dedicated tutor who is an expert in their subject area. They provide as much or as little individual contact as you require. You can contact your tutor whenever you need – your hours are not limited.
Feedback and Assignments Tutor Feedback is an essential component in helping you understand the subject matter. Tutor feedback is given in the form of notes written on the assignment. We encourage you to contact your Tutor where help with clarification and understanding of course material may be required.
Your assignments are located at the end of each lesson. You submit them for marking whenever you are ready. There is no time limit.
Set Tasks and Self-Tests Most modules have a Set Task at the end of each lesson before for the assignment. This is where you get the opportunity to undertake practical work to help you acquire knowledge, skills and practical experience. Many modules also have short Self-Tests.
Exams Once all assignments have been completed you may then elect to sit for a one and half hour exam in your own location. If you prefer not to take the exam you do have the option to undertake a project instead. Once the exam or project part of the course is completed, your Certificate is then processed. Please allow approximately 4 weeks for this.
Design Your Own Qualification ADL offers students the flexibility to self-design their own qualification – bundling together a combination of 100-hour modules into a qualification higher than a certificate.

Assessments
Q. Assessment – how does it work? A. For each 100 hour module you are assessed by assignments (at the end of each lesson) and a final one and a half hour exam (or you may elect to complete a project instead of sitting the exam) – the choice is yours – you sit for the exam in your own location, or you can visit us in Canterbury, England to sit the exam if want to. Exam fees are included in the tuition fee you paid. You can read more about the examination process here. At the end of each lesson, there is an assignment. You submit it to the academy who then submits it to the tutor for marking, comments and feedback. Our policy is to have a grade for you within 5 to 7 days.
Q. If my assignment is not up to standard is there an opportunity to resubmit my work? A. Yes – If you’re not happy with your work submitted you may re-submit the assignment again.
Q. How many assignments do I need to complete for each module? A. At the end of each lesson, there is an assignment – so if a course has say, 10 lessons there would be 10 assignments. The number of lessons per module varies from module to module. See the course content from our website for further details.
Q. When do I have to hand in my first assignment? A. There is no deadline for handing in the first assignment. Submit when you are ready. There are some students who hand in assignments within the first couple of weeks of enrolment – while there are others who submit their work 6 months later. It’s all at your own convenience to suit you. Everyone has different work and home commitments and we cater to these needs.
Q. I am having difficulty attending workshops/industry meetings, what can be done? A. If your course requires attendance at workshops, conferences, or industry meetings; alternative arrangements can be made in your country; however, there may be an additional expense. We can appoint an appropriately qualified person anywhere to work through curriculum documentation supplied by us, to satisfy the requirements set down in a course.
Qualifications
Q. What qualification will I receive? A. For individual modules, you would receive a Certificate (providing you complete all assignments and the exam). If you just want to complete the assignments only, then a Letter of Achievement would be awarded. For more details on qualifications awarded please click here.
Q. Is there a next level to progress to? A. Yes – you can progress from one module to a combination of many modules and to higher qualifications i.e. Advanced Certificates, Diplomas and Higher Advanced Diplomas. Read more about course levels here.
Q. Can I customize my diploma/higher qualification? A. Not all educational institution’s certificates /diplomas meet everyone’s needs. The opportunity to design your own diploma at the Academy (subject to our approval) is an added bonus, not found at other colleges. It’s a very popular option and widely used by many students. You quite simply choose the appropriate number of related modules needed to complete the qualification and submit them to us for approval as a custom diploma.
Q. What do I get when I complete the course? Will I receive a transcript? A. At the completion of a 100-hour Certificate course and providing all assignments and exam have been completed, you will receive a Certificate and Transcript. The Transcript will list your GPA. Each 100-hour module is worth 3 credit hours.
Exams
Q. Do I have to sit for an exam? A. Exams are optional but need to be undertaken in order to receive the Certificate or higher qualification. Exams are one and a half hours long. You appoint an adjudicator (subject to our approval) to supervise the exam. You sit for the exam in your own location. Its that simple.
Q. I don’t cope well with exams – what can I do? A. If you feel you don’t cope well with exams you may elect to undertake a Project (set by the tutor) instead of sitting the exam. Many students prefer this option as they find researching the material for the project sharpens their research skills.
Q. If I don’t sit for the Exam do I still get a qualification? A. If you don’t sit for the exam but complete the project alternative, you will still receive your endorsed qualification. If you don’t sit for an exam or complete a final project, providing you have completed all the assignments you will be awarded a Certificate of Achievement.
Q. Do I have to sit for the exam at the Academy? A. No – whilst you are more than welcome to come to our location in Canterbury, U.K. and sit the exam in our classroom; the more popular option is to sit for the exam in your own location. You appoint an adjudicator to supervise the exam. Click here for more information on that process.
