Glass jars with sieve lids, for sprouts and kitchen microgreens

This sprouter germinates your seeds in a 1 L glass jar, placed upside down on its stand: the rinsing water drains through the stainless steel mesh lid, and the sprouts grow in the open air, without soil. After 8 to 12 hours of soaking, radish, broccoli or mung bean seeds give sprouts to eat raw, prepared on a corner of the worktop. The complete kit adds to each jar a grid tray for leafy microgreens, a sachet of organic seeds and a growing guide.

🫙 The jar and its sieve

A sprouting jar works by successive rinses, not from a reserve of water. You fill the jar with fresh water through the lid, swirl it gently, then drain through the same strainer, whose fine mesh holds back the seeds. The jar then returns to its stand, tilted neck-down above its tray: the remaining water drains away, air circulates between the seeds, and nothing stagnates at the bottom. This rinse, repeated 2 to 3 times a day, provides the moisture the seed needs and washes away the residues that would make the batch ferment. The glass lets you follow germination at any time, and it goes in the dishwasher with the lid between batches.

Soaking, 8 to 12 hours

The dry seeds swell in the jar filled with fresh water, then you drain this water through the strainer before the first rinse.

Germination, 2 to 10 days

The jar stays tilted on its stand, out of direct sunlight, and is rinsed 2 to 3 times a day until the sprouts emerge.

Light, 2 to 14 days

Near a window, in indirect light, the sprouts turn green; harvest falls between the 4th and 21st day depending on the species.

Organic seeds for the next batches

The complete kit supplies one sachet of organic seeds per jar, enough to start your first batches as soon as you open the parcel. For later on, the organic sprouting seed sets bring together 10 or 20 varieties in separate sachets, from legumes to brassicas, and their instructions use the same soaking and rinsing times as the sprouter guide. You can thus grow a different species in each jar and change the flavour with every batch.

The jar drains tilted, never upright

A jar left upright keeps a layer of water at the bottom in which the seeds ferment, which you can recognise by a sour smell and a greyish film. After each rinse, put it back on its stand, neck facing down, above the tray that collects the water, and empty that tray every time. Do not fill the jar with dry seeds beyond a thin layer either, as the seeds swell when soaked and increase several times in volume as they sprout.

🌱 Jar or grid tray

The complete kit offers two ways of getting seeds to sprout, and each suits a different group. The jar produces sprouts, that is, germinated seeds eaten whole, shoot and root included: mung bean, radish, broccoli, lentil and alfalfa all do well in it. The mesh tray produces microgreens, young leafy seedlings that are cut above the mesh. The seeds are spread in a single layer with the mesh resting on the tray, and the leaves turn green in the light while the roots cling to the mesh. Cress, whose seeds are coated in a sticky mucilage and form a compact mass in a jar, does better on the mesh. If a batch sprouts poorly, our article on germination failures and their causes will help you find the source of the problem.

📦 Complete kit or jars only

The complete kit includes, for each jar, a stand, a tray, a grid and a packet of organic seeds, along with a shared growing guide and access to the 10-part ZenGreens video course. It suits a first purchase, as it lets you start a batch the moment the parcel is opened. The jars-only version, with 2 or 3 jars, contains the 1 L jars and their sieve lids: it is aimed at those who already have their seeds and their method, or who want to add stations to a kit already in use. Choose the number of jars according to how much you eat, because one jar produces one batch at a time, whereas two or three jars staggered by a few days give an almost continuous harvest.

🔁 Staggering the batches

Three jars started on the same day give you three harvests on the same day, then several days with nothing. Instead, stagger each new batch by 3 or 4 days from the previous one, and you will have sprouts ready at regular intervals. Sow only one species per jar as well, because the seeds in a mix differ in size and in how quickly they germinate, so the fastest are ready before the others have even come up. Once harvested, the sprouts should be rinsed, drained thoroughly and kept for a few days in the fridge in a closed container. To choose where to put the sprouter in your kitchen, our guide to setting up an indoor seedling area explains the light and temperature that suit them.

How do you start a batch in a jar, step by step?

Pour a thin layer of seeds into the bottom of the jar, cover with fresh water and leave to soak for 8 to 12 hours.
Drain the soaking water through the sieve lid.
Place the jar tilted on its stand, neck downwards, above the tray.
Rinse 2 to 3 times a day: fill, swirl gently, drain, then put the jar back on its stand.
When the sprouts have reached the desired size, place the jar in indirect light so that they turn green.
Harvest, rinse one last time and drain thoroughly before refrigerating.

Jar or grid tray: which one for which seed?

Container	What it gives	Suitable seeds
Jar	Sprouts to eat whole, root included	Mung bean, radish, broccoli, lentil, alfalfa
Tray with grid	Leafy microgreens, cut above the grid	Cress and small seeds that stick together

One, two or three jars: what difference does the number make?

Number	What you can do	Who it suits
1 jar	One batch at a time, with a gap between two harvests.	A first try, or sprouts now and then.
2 jars	Two batches staggered by a few days, with no break between harvests.	Anyone who wants sprouts every week, of one or two varieties.
3 jars	Three varieties in parallel, and a harvest coming round every 3 or 4 days.	Anyone who cooks often and likes to vary the flavours.

What does the complete kit contain, and what do the jars contain on their own?

The complete kit includes, for each jar, the 1 L glass jar and its sieve lid, a stand, a tray, a grid and a sachet of organic seeds, together with a growing guide and access to a video course in 10 parts. The jars on their own, in sets of 2 or 3, include the jars and their sieve lids.

The 3 jar kit contains mung bean, broccoli raab and radish seeds, all from organic farming.

How do you prevent mould in the jar?

Three habits, applied together, prevent them. The first is draining: after each rinse, the jar goes back tilted on its stand and never keeps water at the bottom. The second is regular rinsing, 2 to 3 times a day, which refreshes the water around the seeds. The third is a thorough wash of the jar and lid between two batches, in hot water or in the dishwasher. A sour smell or a grey film means the batch should be thrown away, and the jar should be washed before the next batch.
