Microgreens Malaysia: How to Grow Them at Home (Cara Tanam Microgreens)
Growing microgreens in Malaysia is simple: sow seeds thickly on a shallow tray of moist growing medium, keep them covered in the dark for 2–4 days until they sprout, then move them to bright light with good airflow and harvest with scissors once the first leaves open, usually 7–14 days after sowing. The one local challenge is mould, because our warm, humid air is ideal for fungus. Good airflow, bottom watering and not oversowing solve most of it.
Microgreens are young seedlings of vegetables and herbs harvested just after the first leaves (cotyledons) appear. They're different from sprouts (taugeh), which are eaten whole with the seed and root and grown in water. This guide is for growing them at home, on a kitchen counter, windowsill or condo balcony.
What You Need
| Item | Notes |
|---|---|
| Shallow trays | Two trays: one with drainage holes for growing, one without for bottom watering. Recycled food containers work if you poke holes |
| Growing medium | Cocopeat, fine potting mix, or hemp or jute grow mats |
| Seeds | Buy seeds sold for microgreens or sprouting, untreated |
| Spray bottle | For misting seeds in the first days |
| Cover | A second tray, plate or lid to block light during germination |
| Light | Bright windowsill, shaded balcony or a small LED grow light |
| Scissors | Clean and sharp for harvesting |

Best Microgreens to Grow in Malaysia
Fast-growing crops are easiest in our climate, because a short grow time leaves less window for mould.
| Microgreen | Days to harvest (approx.) | Difficulty | Flavour | Tips |
|---|---|---|---|---|
| Radish (lobak) | 7–10 | Very easy | Peppery | Fastest and most forgiving first crop |
| Mustard (sawi) | 7–12 | Easy | Spicy | Grows fast in warm weather |
| Kangkung | 7–10 | Easy | Mild | Large seeds; soak a few hours first |
| Sunflower | 8–12 | Medium | Nutty, crunchy | Soak seeds; remove hulls before eating |
| Pea shoots | 10–14 | Easy | Sweet | Soak overnight; harvest when 8–10 cm |
| Broccoli | 8–12 | Easy | Mild | Popular; keep airflow good |
| Bayam (amaranth) | 10–14 | Medium | Earthy | Tiny seeds; colourful red types |
| Basil (selasih) | 14–21 | Medium | Aromatic | Slower; seeds go gel-like when wet, so don't oversow |
Times vary with temperature, light and seed variety. In warm Malaysian conditions many crops grow at the faster end.
Microgreens How to Grow: Step by Step
- Soak large seeds. Peas, sunflower and kangkung benefit from soaking for several hours or overnight. Small seeds like broccoli and radish don't need it.
- Prepare the tray. Fill the holed tray with 2–3 cm of moist cocopeat or potting mix, levelled and lightly pressed. Pre-moisten the medium; it should feel like a wrung-out sponge.
- Sow evenly. Scatter seeds densely but in a single layer, with seeds close together but not piled up. Oversowing is the main cause of mould.
- Mist and cover. Mist the seeds, then cover with another tray or plate. Some growers put a light weight on top, which helps roots anchor.
- Blackout period (2–4 days). Keep covered in a shaded spot. Check daily and mist if the surface looks dry.
- Uncover and give light. Once most seeds have sprouted and are pushing up the cover, remove it and move the tray to bright indirect light or under a grow light.
- Bottom water. Pour water into the solid tray underneath and let the medium soak it up for 10–15 minutes, then pour off the excess. Watering from the top wets the leaves and invites mould.
- Harvest. Cut just above the soil with clean scissors once the first leaves are fully open, or when the first true leaves appear. Rinse gently and eat fresh.
Most microgreens don't regrow after cutting (pea shoots sometimes give a second, smaller cut). Compost the used medium and sow a fresh tray.
Mould Prevention in Humid Air
This is the part most overseas guides skip, and it matters most in Malaysia.
- Airflow is everything. Run a small fan on low near the trays for a few hours a day, or grow near an open window. Still, humid air is the biggest mould trigger.
- Don't oversow. Crowded seeds trap moisture.
- Bottom water only after the blackout stage, and don't leave water standing in the tray.
- Keep it clean. Wash trays between batches with soapy water and rinse well.
- Don't keep trays in a closed cupboard after they sprout.
- Harvest on time. Overgrown microgreens get crowded and start to rot at the base.
Mould or root hairs? Fine white fuzz on the roots right after sprouting is usually root hairs, which are normal. Mist them and they collapse. Grey, web-like fuzz on the soil surface or stems that spreads, smells musty, or makes stems mushy is mould. Discard that tray rather than eating it.
Light and Location
- Windowsill or balcony: bright indirect light is enough. Harsh afternoon sun can dry out a shallow tray within hours on a hot day.
- Indoors under an LED: a small grow light 10–20 cm above the tray for 12–16 hours a day gives even, green growth.
- Pale, leggy, leaning seedlings mean too little light.
Malaysia's heat speeds growth but also dries trays faster, so check moisture daily, especially on balconies.
Microgreens Benefits: What We Can Say
Microgreens are a fresh, flavourful way to add vegetables to meals: toss them into salads, sandwiches, nasi lemak, omelettes or noodles. Some studies have found that certain microgreens contain higher concentrations of some nutrients than the mature vegetable, but this varies widely by crop and growing conditions. Treat them as a healthy addition to your diet, not a supplement or medicine.
About selling microgreens: some Malaysians sell microgreens to cafés and neighbours. We don't make any income claims. If you're thinking of selling, start small, learn your local demand, and check food safety and business registration requirements with the relevant authorities first.
Food Safety
- Use seeds sold for eating, sprouting or microgreens, not garden seeds coated with fungicide (often brightly coloured).
- Wash hands and tools before handling.
- Rinse microgreens before eating and store in the fridge in a container with a paper towel. Most keep for several days.
Frequently Asked Questions
Microgreens apa yang paling senang ditanam?
Lobak (radish), sawi dan kangkung paling senang untuk permulaan. Ia tumbuh cepat, biasanya boleh dituai dalam masa 7 hingga 10 hari, dan kurang berisiko berkulat.
Kenapa microgreens saya berkulat?
Biasanya sebab biji terlalu rapat, air terlalu banyak atau udara tak bergerak. Kurangkan biji, siram dari bawah dulang, dan letak kipas kecil supaya ada aliran udara. Kalau kulat kelabu dah merebak, buang dulang tersebut.
How long do microgreens take to grow in Malaysia?
Most take about 7–14 days. Radish and mustard are among the fastest; basil is slower at around 2–3 weeks.
Do microgreens need sunlight?
They need light after sprouting, but not harsh direct sun. A bright windowsill, shaded balcony or LED grow light works well.
Can I grow microgreens without soil?
Yes. Hemp mats, jute mats or even damp paper towels can work for small seeds, though cocopeat or fine potting mix usually gives stronger growth.
