"Ponics" means
to cultivate or work
9
"HYDROPONICS"
is therefore the cultivation of crops using NUTRIENT WATER as the MAIN component, some systems also include a MEDIUM (special material)
10
2 Main Types of HYDROPONIC systems
-Systems that use nutrient water ONLY
-Systems that use a growth medium (special material) & nutrient water
11
Multiple Choice
12
Yes! The system at School is a Nutrient Water with Medium (Special Material) system.
(Cocopeat is the special media)
13
14
[1st example] DEEP WATER SYSTEM
[plants are suspended in a large volume of nutrient water]
- roots are in greater contact with nutrient water
- simple setup compared to other water only systems
15
[2nd example] NFT (Nutrient Film Technique)
[plants a suspended in a thin layer of nutrient water]
-less water used
-less contamination closed system
16
17
[1st example] Bucket System
Uses buckets or bags filled with media which are fed by nutrient water
- can grow root crops (carrots, beet)
- can grow bearing crops (peppers, tomatoes)
18
[2nd example] Grow Bed system
Uses a bed of material that is fed with nutrient water.
- open system less disease spread
- no need to aerate water
19
The various types of SPECIAL MEDIUM used.
1)rockwool
2)oasis cube
3)expanded clay
4) Coco peat/fibre (used in our school system)
5) Perlite
6) Vermiculite
7)Rocks/Gravel
20
The hydroponics system at RLSS stats:
- Two systems in one (box and bag system)
- Drip irrigation used (fully automated)
- Electricity driven system (pumps)
- Uses Cocopeat as its media

Multiple Choice
How are the nutrients delivered to the plants in hydroponic systems?
24
Leafy crops & seasonings are best suited for hydroponic systems
- e.g Lettuce, pakchoi, Celery, Chive
- They are shallow rooted
- They are short term

Multiple Choice
What type of crops are BEST suited for hydroponic systems?
28
Why use Hydroponics?
Major Advantages
- Save water
- Uses less space
- Fewer pests
- Fewer Weeds
29
Some Drawbacks
Disadvantages include
- high setup costs
- technical knowledge/skill needed to setup & maintain
