Sprouting Supplies: What You Need to Start Sprouting at Home

Most sprouting supply lists make it sound like you need a full shopping cart. You do not. To sprout at home you need four things: a jar with a wide opening, a mesh sprouting lid, a way to drain the jar at an angle, and seed that is labeled and tested for sprouting. A salad spinner, a blackout sleeve, and sprouting trays make life easier or open up more crops, but your first batch does not need any of them.

We have been growing microgreens since 2018, and we sprout at home too. Below are the supplies we recommend, the ones that are optional, and the ones you can skip. Sprouts grow in water with no growing medium, so the list stays short.

What Supplies Do You Need to Sprout at Home?

Five things get you from dry seed to a jar of sprouts:

• A straight wall jar with a wide opening. We are switching to these straight wall jars because sprouts slide out so much more easily
• A mesh sprouting lid that fits the jar and holds your smallest seed, such as these sprouting lids
• A stand, rack, or bowl that holds the jar mouth down at an angle so water drains out
• Seed labeled and tested for sprouting, bought from a reputable supplier
• Clean, cool water for soaking and rinsing, plus a way to wash and sanitize your gear between batches

Three extras make the routine smoother: a salad spinner for drying, a blackout sleeve or cover for the jar, and a paper towel lined container for the refrigerator. Stacking sprouting trays and a clay saucer are optional, and only needed for specific crops or larger setups. Our sprouting supplies list on Amazon has the jars, lids, salad spinner, and seed in one place. The jars and lids are sold separately, not as a kit.

Sprouting Supplies Checklist

Jars: Why We Are Moving to Straight Wall

The jar is where every batch lives, so it is the one supply worth thinking about. Sprouts fill the jar as they grow, and getting them out in one piece is the hard part. A jar with shoulders can catch a dense clump on the way out. That is why we are about to start using straight wall jars. The sides run straight up, so the sprouts slide out in one go instead of needing a fork and some patience. A wide opening also gives the lid a bigger screen, which helps water drain faster.

Fill the jar less than you think you should. Small seeds swell to four to eight times their dry volume, so for a quart jar, roughly one tablespoon of alfalfa seed or two tablespoons of broccoli seed is enough. Our step-by-step guides cover the exact method for alfalfa sprouts in a mason jar, broccoli sprouts in a mason jar, and salad mix sprouts in a mason jar.

Here is what the setup looks like from the first soak to harvest day.

Sprouting Lids: Pick a Mesh That Holds Your Seed

A sprouting lid replaces the solid lid on your jar. The screen lets rinse water out and air in while keeping the seed inside. What matters is that the screen is fine enough to hold your smallest seed, since alfalfa and broccoli seed are tiny, and that the lid fits your jar snugly so it does not slide off when you tip it. We have sprouting lids on our list, sold on their own so you can pair them with the jars above.

Whatever lid you buy, test it before the first batch. Fill the jar with water, tip it, and check that water flows out without spilling over the edge.

A Drain Stand Keeps Sprouts From Sitting in Water

Standing water is the most common cause of a failed or unsafe batch. After every rinse, the jar needs to drain completely. A jar stand holds the jar at an angle with the mouth down, so water runs out while air moves in. A dish rack, or a bowl with the jar tipped against its edge, does the same job, so you do not need to buy a stand to start.

We keep our jars on a wire jar rack with trays, and we usually have three jars in rotation so there is always a batch at a different stage.

Blackout Sleeves Keep the Jar Dark

Most sprouts grow in the dark and only get a short stretch of indirect light at the end, for crops that green. A blackout sleeve or cover slides over the jar and keeps light off it between rinses. The sprouting jar set we have used so far comes with blackout sleeves. A dark cabinet also works, but a sleeve lets you leave the jars on the counter where you will remember to rinse them.

Sprouting Seed: The One Supply You Cannot Compromise On

Buy seed that is labeled and tested for sprouting, from a reputable supplier. Sprouting seed is tested for bacteria such as E. coli O157 and Salmonella. Garden seed, bulk food-grade seed, and bird seed are not grown, handled, or tested for sprouting, and the warm, wet conditions inside a jar are ideal for any bacteria that came in on the seed. This is a food safety requirement, not a preference.

True Leaf Market is our default seed source and carries sprouting seed as well as microgreen seed, and our Amazon list includes sprouting seed too. Our seed guide explains the difference between microgreen seed and sprouting seed, which is worth reading before you buy.

For a first jar, pick a fast, forgiving crop. Broccoli, alfalfa, radish, mung bean, and lentil all finish quickly. We have step-by-step guides for alfalfa, broccoli, and salad mix.

Two safety rules apply to seed you already have at home. Never sprout tomato, pepper, eggplant, or potato seed, since nightshade seeds and sprouts contain toxic compounds. And never eat kidney beans raw or raw-sprouted. If you are unsure whether a seed is a safe sprouting crop, check before you soak it.

A Salad Spinner Dries Sprouts for Storage

Sprouts go in the refrigerator dry, not wet, and drying them well is the biggest factor in how long a batch keeps. A salad spinner is the tool we recommend for it. Pull the finished sprouts out of the jar into the basket, rinse the loose seed hulls off in the bowl, spin, then move the sprouts to a container lined with a paper towel. As a general rule, most sprouts keep about a week refrigerated, and bean and sunflower sprouts keep less.

Clean Supplies Matter as Much as Clean Seed

Wash the jar, lid, and stand with hot, soapy water after every batch, rinse them well, and sanitize before the next one. Some growers add a food-safe hydrogen peroxide step, which is optional. If you use one, follow the product label. Never start a new batch in a jar that still has residue from the last one.

Throw a batch out if it smells musty, fishy, or rotten, or if it shows fuzzy gray or black mold. Do not try to rescue it. White root hairs, which look like fine fuzz around day three or four, are normal and are not mold.

Optional Supplies: Sprouting Trays and Clay Saucers

Jars handle most sprouting crops. Trays and clay saucers are for the exceptions and for larger setups.

Some seeds form a gel coat when wet and cannot be jar-sprouted. They clump, hold water, and rot. This list includes chia, flax, basil, cress, arugula, watercress, psyllium, canola, and nigella. These seeds need a soaked unglazed clay saucer or a tray, misted rather than rinsed and drained.

Stacking sprouting trays hold several batches in one stack and are watered rather than rinsed. We no longer sell sprouting trays, but the ones we recommend are on our sprouting trays list. One note to avoid confusion: our post on growing microgreens in a sprouting tray is a microgreens method, where the seed grows in a medium and only the shoots are eaten. That is a different crop from sprouts.

What to Skip When You Buy Sprouting Supplies

Save your money on these:

• Soil, coco coir, or any growing medium. Sprouts are grown in water. A medium is for microgreens, and our post on sprouts, microgreens, baby greens, and mature greens explains where each stage fits.
• Garden seed, bulk food-grade seed, and bird seed, for the safety reasons above.
• Narrow-mouth jars, which are hard to drain and hard to empty.
• Kits that ship with seed of unknown source. Check that the seed is labeled and tested for sprouting.

If you are weighing sprouts against microgreens, read why we grow both sprouts and microgreens at home. We eat the whole sprout, root and shoot. We do not eat microgreen roots, and here is why.

Keep Track of Your Jars With Sprouting Tracker

Once you have a few jars going, the hard part is remembering which one needs a rinse and when they are ready for light or harvest. Sprouting Tracker is our phone-first web app for that. Pick a crop and a vessel, and it sets the soak, the rinse times, and the harvest window. It handles glass jars, stacking trays, and clay saucers, and every screen uses the right word for each: rinsed, watered, or misted. Reminders arrive at the times you choose, and with several jars you can tick a group and rinse them in one tap. iPhone reminders need iOS 16.4 or later and the app added to the Home Screen.

One limit worth stating plainly: the app tracks jars, but it cannot determine whether sprouts are safe to eat. Rinsing is a quality step and does not decontaminate seed.

Sprouting Supplies FAQ

What is the minimum equipment for sprouting?

A jar with a wide opening, a mesh sprouting lid, a stand or bowl to hold the jar at a draining angle, and seed labeled and tested for sprouting. A salad spinner, blackout cover, and trays are helpful but not required.

Do I need a straight wall jar?

No, a standard wide-mouth mason jar works. We are switching to straight wall jars because the sprouts slide out more easily at harvest. Choose a wide opening either way, since it makes rinsing, draining, and harvesting easier.

Can I use garden seeds or bulk seed from the store?

No. Use seed labeled and tested for sprouting from a reputable supplier. Garden seed, bulk food-grade seed, and bird seed are not tested for sprouting, and raw sprouts are a documented source of foodborne illness.

Do I need a sprouting tray?

Not for most crops. Jars handle alfalfa, broccoli, radish, mung bean, lentil, and many others. You need a tray or an unglazed clay saucer only for seeds that cannot be jar-sprouted, such as chia, flax, basil, cress, and arugula.

Do I need a salad spinner?

Not to start, but drying sprouts before refrigerating them makes a big difference in how long a batch keeps. A salad spinner is the easiest way to do it.

How many jars should I start with?

Start with one jar and learn the rinse routine, then add more. We usually keep three jars in rotation so there is always a batch at a different stage.

Is there an app to track sprouting?

Yes. Sprouting Tracker is a phone-first web app for jar sprouting. You pick a crop and a vessel, and it sets the soak, the rinse reminders, and the harvest window. It works with glass jars, stacking trays, and clay saucers. It tracks your jars, but it cannot determine whether sprouts are safe to eat, so seed labeled and tested for sprouting and clean supplies still matter.

Who should avoid raw sprouts?

FDA and CDC guidance is that children, older adults, pregnant people, and anyone with a weakened immune system, including people undergoing cancer treatment, people with HIV or AIDS, and people with diabetes, should avoid raw sprouts and eat them only if thoroughly cooked.

Final Thoughts

A jar, a mesh lid, a drain stand, and tested sprouting seed are all you need for a first batch. Add a salad spinner and a blackout sleeve when you want the routine to be easier, and add trays or clay only when you reach seeds that need them.
