Best Growseed seeds and growing kits for home growing compared in 2026

Growing your own food at home can start with a single packet of seeds or a ready-made kit. This roundup compares six Growseed products: a windowsill starter kit, a large microgreen kit and four seed packets covering chillies, a sweet pepper and two kinds of tomato. Prices run from 99p to £29.99. Which one suits you depends on whether you want everything in one box, a quick crop of microgreens, or a particular plant for a pot, basket or taller growing space. This is desk research based on the product details supplied, not hands-on testing.

Our stand-out pick

Grow Your Own Kit, Tomato, Sweet Pepper or Chilli

The Grow Your Own Kit, Tomato, Sweet Pepper or Chilli is the best all-round pick on the facts supplied. For £9.99 it bundles 50 seeds of the variety you choose at purchase, a half-size tray and lid, Growseed soil mix and a plant marker, so a beginner has what they need to start seeds on a windowsill in one purchase. The seed packets are cheaper, but they cover only the seeds. The microgreen kit has a wider range of contents, though it costs three times as much. This choice comes from comparing the supplied facts, not from testing.

The details

Six Growseed seeds and growing kits compared

01 · Best Starter Kit

Grow Your Own Kit, Tomato, Sweet Pepper or Chilli

A windowsill-sized seed-starting kit that packs seeds, tray, lid, soil mix and a marker into one £9.99 purchase.

The Grow Your Own Kit, Tomato, Sweet Pepper or Chilli is built for gardeners who would rather not gather supplies separately. The box holds 50 seeds of your chosen variety, a half-size tray with a lid, Growseed soil mix and one plant marker. It is described as a windowsill-sized seed-starting kit, so it suits a small home or a flat where space is tight. You pick tomato, sweet pepper or chilli when you order, which is worth deciding before you check out. With 50 seeds in the box, there is also scope to sow a good number of plants from a single kit.

02 · Best Microgreen Kit

Large Microgreen Seed Growing Kit

A broad microgreen set with a bamboo-and-rice tray, three coir mats and nine seed packets for £29.99.

The Large Microgreen Seed Growing Kit is the only microgreen product in this group and the biggest-ticket item. The contents are a bamboo-and-rice seed tray, three coir growing mats and nine packets of microgreen seeds. Having nine packets means you can sow several different seeds rather than relying on a single type. The retailer says the coir mats can be composted after use, which is handy if you like to keep waste down. It is a fuller package than any of the other products here, and it is priced to match.

Price snapshot: £29.99 at Growseed, recorded 2026-11-03. Check the retailer page for the current price.

Key specifications

03 · Best for Container Chillies

Demon Red Chilli Seeds

A dwarf, container-friendly chilli for £1.95, with a 30,000–50,000 Scoville heat rating.

Demon Red Chilli Seeds are aimed at growers who want chillies in pots rather than in the ground. The listing describes a dwarf, container-friendly plant, which makes it a candidate for a patio, balcony or sunny sill. Germination is listed at 7–14 days, so it is worth planning your sowing around a window of up to two weeks. The heat rating of 30,000–50,000 Scoville places it firmly in the hot category. A packet holds 5 seeds, enough for a small group of plants.

Price snapshot: £1.95 at Growseed, recorded 2026-11-03. Check the retailer page for the current price.

Key specifications

Product type: Chilli seeds
Packet contents: 5 seeds
Germination: 7–14 days
Plant form: Dwarf, container-friendly chilli
Heat: 30,000–50,000 Scoville

What stands out

Dwarf, container-friendly growth habit suits pots
Heat rating of 30,000–50,000 Scoville for those who like a hot chilli

Things to consider

A packet contains only 5 seeds, which limits how many plants you can raise

04 · Best for Beefsteak Tomatoes

Black Russian Tomato Seeds

Beefsteak tomato seeds with mahogany-coloured fruit, priced at just £0.99 a packet.

Black Russian Tomato Seeds are the cheapest product in the roundup and the only beefsteak tomato. It is an indeterminate type, and the listing describes plants of about 200 cm tall with a 50 cm spread. That is a tall, fairly narrow plant, so it makes sense to think about supports and headroom before sowing. The fruit is described as mahogany-coloured, which sets it apart from a standard red tomato. It suits growers who have the height to give a vine tomato room.

Price snapshot: £0.99 at Growseed, recorded 2026-11-03. Check the retailer page for the current price.

Key specifications

Product type: Tomato seeds
Tomato type: Beefsteak, indeterminate
Fruit: Mahogany-coloured
Mature plant size: About 200 cm tall x 50 cm spread

What stands out

Mahogany-coloured beefsteak fruit gives something different from a standard red tomato
At £0.99 it is the lowest-priced product here

Things to consider

Plants reach about 200 cm tall, so they need plenty of vertical space

View Growseed

05 · Best for Compact Peppers

Lunch Box Sweet Pepper Seeds

A compact, container-friendly sweet pepper mix with 7–10 day germination for £1.35.

Lunch Box Sweet Pepper Seeds are a compact mix intended for container growing. Plants reach up to 90 cm tall by 45 cm spread, which is a manageable size for a patio pot or a spot by the back door. Germination is listed at 7–10 days, a shorter window than the Demon Red chilli. Each packet holds 5 seeds, enough to fill a few pots. It is a tidy, low-cost way to grow sweet peppers where garden space is limited.

Price snapshot: £1.35 at Growseed, recorded 2026-11-03. Check the retailer page for the current price.

Key specifications

Product type: Sweet pepper seeds
Packet contents: 5 seeds
Germination: 7–10 days
Plant form: Compact, container-friendly mix
Mature plant size: Up to 90 cm tall x 45 cm spread

What stands out

Compact plants reaching up to 90 cm tall suit containers
Germination is listed at 7–10 days, shorter than the chilli seeds here

Things to consider

Each packet holds only 5 seeds

06 · Best for Hanging Baskets

Tumbling Tom Tomato Seeds

A trailing tomato for containers and hanging baskets, priced at £1.25.

Tumbling Tom Tomato Seeds are the one trailing variety in this group. The product page recommends them for containers and hanging baskets, and lists them among its patio and kitchen-garden varieties. That makes them a natural fit for small gardens, balconies and sunny doorways where a ground bed is not an option. The trailing habit means they can hang over the edge of a basket rather than climbing up a cane. At £1.25 a packet, they cost less than the pepper and chilli seeds.

Price snapshot: £1.25 at Growseed, recorded 2026-11-03. Check the retailer page for the current price.

Key specifications

Product type: Tomato seeds
Tomato type: Trailing tomato
Suitable for: Containers and hanging baskets
Growing category: Patio and kitchen-garden variety

What stands out

Trailing habit suits hanging baskets and containers
Listed among patio and kitchen-garden varieties, so well suited to small spaces

Things to consider

The number of seeds per packet was not confirmed, so the value per seed is hard to judge
