Sprouting Seeds for Fresh Jar and Tray Sprouts

Say it's February, you want something crunchy in a sandwich, and you don't have a garden. One jar, a spoonful of seed and about five days is the entire setup. If you can't decide where to start, the Sprouting Salad Mix seeds put mung bean, alfalfa, lentil, fenugreek and yellow mustard in the same jar, so one batch gives you five flavours instead of one.

Your First Jar of Sprouts, Start to Plate

Soak time and rinse-and-drain cycle

With the salad mix, soak the seeds for about 8 hours and drain thoroughly, then rinse and drain twice a day. Once sprouts show, park the jar somewhere well lit until they reach the size you want. Alfalfa sprouts seeds (Medicago sativa) work the same way: soak 8-10 hours in cool water, drain well, spread the seeds out in the jar, then leave them for 10 hours at room temperature away from direct light before the next rinse. Draining is the step people rush, and it's the one that matters most, so tip the jar at an angle and keep water off the crown.

Germination rate and days to harvest

Alfalfa takes around 5 days and comes out fine and grassy. Basil sprouts seeds (Ocimum basilicum) get sown thick in a propagator and are ready in roughly 10 days, with that same sweet aniseed smell you get off the full-grown herb. Mung bean sprouts seeds (Vigna radiata) sprout happily between damp paper towels and are best used at about 4-5 cm, when they still snap and taste watery-fresh. Rocket sprouts seeds (Eruca sativa) bring the peppery bite, cress sprouts seeds (Lepidium sativum) are the fastest of the lot and grow all year round at around 20-22°C, and broccoli (Brassica oleracea) is the one exception here: sow those in a pot in early spring with plenty of sun and a little water, and you're picking in August. Germination rate is the other half of the timing, and it slips with old or damp seed, so buy the amount you'll actually get through.

Seed hulls and hull rinsing

Sprouts get eaten whole, seed and all, so hull rinsing is part of the job. As alfalfa and rocket push up, the papery seed hulls come loose and float, and a swirl of water at each rinse carries most of them away. Rinse with clean drinking water, wash the jar and lid between batches, and wash your hands before you handle wet seed. Watch out for standing water: leave a puddle in there overnight and the whole batch smells sour by morning, and at that point it goes in the bin, not on your plate. Keep the bag dry and cool and it stays viable for a long while.

Jar, Tray or Paper Towel, and Which Seed We'd Buy First

Sprouting tray and stackable sprouter, or just a jar

A jar with a mesh lid, or a jar with muslin tied over the top, handles alfalfa, mung bean and the salad mix without any fuss. A sprouting tray and stackable sprouter are the usual step up for the leafier ones, basil and cress especially, because you snip them off rather than tip them out, though we don't sell sprouting equipment on this shelf. Paper towels are the cheapest way in and fine for mung beans, but they dry out if you forget a rinse, so a jar is more forgiving. One thing worth separating: Microgreens are their own Zamnesia category, not these. Sprouts spend a few days in water and are eaten whole, seed included, while microgreens grow on in substrate and get cut above the seed. The honest gap in this shelf: no radish, pea shoot or red clover, just the seven types listed above. If it's your first go, get cress for speed and the Sprouting Salad Mix for variety, and keep single-variety alfalfa for when you know which one you actually eat most.
