Urban Farming with Hydroponics: Grow Fresh Food Without Soil
Why hydroponics is booming in land-scarce Singapore
Singapore imports more than 90% of its food, and the national "30 by 30" goal aims to produce 30% of our nutritional needs locally by 2030. Hydroponics — growing plants in nutrient-rich water instead of soil — is at the heart of that push. It uses up to 90% less water than traditional farming, needs no arable land, and can run indoors under LED lights all year round.
What exactly is hydroponics?
Hydroponics delivers water, oxygen and dissolved nutrients directly to plant roots, so plants grow faster and cleaner without soil. The common beginner-friendly systems are:
- Deep Water Culture (DWC) — roots sit in oxygenated nutrient water; simplest to start with
- Nutrient Film Technique (NFT) — a thin film of nutrient solution flows past the roots in channels
- Kratky method — a passive, no-pump setup ideal for herbs and small greens
- Ebb and flow — periodically floods and drains the grow bed
What you can grow
| Crop | Time to harvest |
|---|---|
| Lettuce, bok choy, kai lan | 3 to 5 weeks |
| Basil, mint, coriander | 3 to 6 weeks |
| Kale, spinach, chye sim | 4 to 6 weeks |
| Cherry tomatoes, chilli | 8 to 12 weeks |
In our hands-on class you build and run a working hydroponic system, learn to mix nutrients, balance pH and EC, and troubleshoot common problems. The WSQ Basic Urban Farming with Hydroponics course takes you from zero to your first harvest.
Who should learn this?
- Home gardeners who want fresh, pesticide-free greens year-round
- Aspiring urban farmers and agripreneurs exploring a new business
- F&B owners wanting to grow their own herbs and microgreens
- Educators, community-garden leaders and sustainability advocates
Fund your learning: WSQ funding + SkillsFuture Credit
This is a WSQ-accredited course, so eligible Singaporeans and PRs enjoy up to 70% WSQ course-fee funding, and Singaporeans can use SkillsFuture Credit to offset the balance — often bringing the out-of-pocket cost close to zero. Company-sponsored staff enjoy the same subsidies plus absentee payroll support. Check your funding eligibility and class dates here.
FAQ
Do I need a garden or balcony?
No. A hydroponic rack fits in a kitchen corner, spare room or office pantry under LED grow lights. We cover compact indoor setups in class.
Can I claim SkillsFuture Credit for this course?
Yes. As a WSQ course it is SkillsFuture-eligible — apply the WSQ subsidy first, then use your SkillsFuture Credit for the nett fee. Our team handles the paperwork.
Is hydroponics hard to maintain?
Once your system is dialled in, it takes only minutes a day. The skill is in the setup and nutrient balance, which is exactly what the course drills.
