When seeds fail to germinate, the seed packet gets blamed. It's usually not the seed — it's the medium they were sown into, or a container that dried out at the wrong moment.
Starting seeds properly requires very little equipment. Most seed-starting "kits" sold online bundle things you don't need alongside the two that matter.

The medium matters more than the tray
This is the part people get wrong. Potting mix and seed-starting medium are not the same thing, and using the former for germination causes a lot of unexplained failures.
Seeds carry their own food supply. They don't need nutrients to germinate — they need moisture, air, and something fine enough for a delicate root to push through. A rich potting mix is too coarse, holds too much water around a tiny seed, and its nutrient content actively increases the risk of damping off, the fungal collapse where seedlings emerge fine and then topple at soil level within a day.
Cocopeat is the practical choice in India. It's cheap, widely available, holds moisture well while staying airy, is fine-textured, and is essentially sterile out of the block — which matters a great deal for damping off.
Buy it as a compressed block rather than loose; it's far cheaper by volume. A 5kg block expands to roughly 75 litres with water.
Cocopeat Block (5kg, expands to ~75L)
If you buy one thing for seed starting, buy this rather than a kit. The medium determines germination success far more than the container does, and cocopeat's near-sterility is the main defence against damping off.

Pros
- Fine, airy texture that delicate seedling roots penetrate easily
- Essentially sterile from the block, which sharply reduces damping-off losses
- Compressed blocks are dramatically cheaper per litre than loose bagged medium
Cons
- Contains almost no nutrients — seedlings must be moved on or fed once true leaves appear
- Some batches are high in salt and need rinsing before use
- Expanding a full block produces far more than a small garden needs at once
Why individual cells beat an open tray
You can germinate seeds in almost any container with drainage. The reason cell trays are worth buying is what happens later, at transplanting.
Seedlings raised together in one open tray have intertwined roots. Separating them tears roots, and torn roots mean transplant shock — often losing seedlings that germinated perfectly. Individual cells let you push out a whole intact root block, which is the single biggest factor in transplanting cleanly. The full method is covered in how to transplant without killing the plant.
On cell size: small cells (98-cell trays) suit greens and anything moved on quickly. Larger cells (50-cell or fewer) suit tomato, brinjal, and chilli, which sit longer before transplanting. Small cells dry out fast and need daily attention in warm weather.
Humidity domes: useful, not essential
A clear dome holds humidity around germinating seeds, which helps for slow or fussy germinators and in dry indoor air.
For most Indian conditions it's optional — ambient humidity is often sufficient, and a sheet of plastic wrap over a tray does the same job for nothing.
What you can skip
Heat mats. Genuinely useful in cold climates. In most of India, ambient temperatures are already in or above the germination range for common vegetables for most of the year. Save the money.
Peat pellets. Convenient, but expensive per seedling compared with cocopeat and cell trays, and the netting on some brands restricts roots if not removed.
Grow lights, unless you're starting seeds indoors in a genuinely dark room. A bright windowsill or a sheltered outdoor spot works for most of the year here.
Expensive "complete" kits. Most bundle a tray, a dome, and a small quantity of medium at a considerable markup over buying a tray and a cocopeat block separately.
Getting germination right
How deep to sow
- Sowing depth: roughly two to three times the seed's diameter. Too deep is the most common error — the seedling exhausts its energy reserve before reaching light. Very fine seeds are pressed onto the surface, not buried.
- Moist, not wet. Cocopeat should feel like a wrung-out sponge. Waterlogged medium rots seeds before they sprout.
- Water from below where possible. Standing the tray briefly in shallow water draws moisture up without dislodging seeds or compacting the surface.
- Label everything. Seedlings of different vegetables look nearly identical at the two-leaf stage, and you will not remember.
- Move them on once true leaves appear. Cocopeat has no nutrients — a seedling left in it past the true-leaf stage stalls and yellows.
Frequently asked questions
Can I use normal potting soil to start seeds?
You can, but germination rates drop. Potting mix is too coarse for delicate roots, holds excess water around small seeds, and its nutrient content raises the risk of damping off. A fine, near-sterile medium like cocopeat performs noticeably better.
Why do my seedlings collapse at the base after sprouting?
That's damping off, a fungal problem caused by overly wet medium, poor airflow, and non-sterile soil. Use a sterile medium such as fresh cocopeat, keep it moist rather than soaked, ensure airflow, and remove any humidity dome as soon as seedlings emerge.
How deep should I sow vegetable seeds?
About two to three times the seed's own diameter. Sowing too deep is the most common cause of failed germination — the seedling runs out of stored energy before reaching the surface. Very fine seeds should be pressed onto the surface rather than buried.
Do I need a heat mat for germinating seeds in India?
Rarely. Heat mats matter in cold climates, but ambient temperatures across most of India already sit within the germination range for common vegetables for most of the year. The money is better spent on good medium and cell trays.
The short version
Buy a cell tray and a cocopeat block; skip the kits, heat mats, and pellets. Rinse the cocopeat, keep it wrung-out-sponge damp, sow at two to three times seed diameter, label everything, and move seedlings on once true leaves appear. The medium and the sowing depth account for most germination success — the equipment barely matters beyond that.
