Frequently Asked Questions
About the Patina Germina
What's that name about?
Patina Germina is derived from Latin and loosely translates to something like “sprouting bowl.” So while the name may sound a little poetic, it simply describes what you’re looking at: a bowl designed for growing sprouts.
If we were being strictly grammatically correct, the name would be Patina Germinanda. But that felt like a few syllables too many for an everyday kitchen object. So we shortened it slightly — a bit of poetic freedom, you could say.
(Sorry, Miko.)
Where can I buy the Patina Germina?
Patina Germina is not available in our shop just yet. We’re planning to launch it via Kickstarter in February, allowing early supporters to help bring the product into production.
By backing the project, you’ll be among the first to receive Patina Germina. If the campaign is successful, we plan to ship rewards in September.
Kickstarter helps us produce Patina Germina thoughtfully and at the right scale — without overproducing or cutting corners. It also allows us to involve our community from the very beginning.
Want to stay informed?
Sign up for our newsletter and we’ll let you know as soon as the campaign goes live.
Where is the Patina Germina made?
Patina sets consist of several parts that come from different suppliers. We aim to source the parts from within Europe when we can.
-The cardboard boxes are made in the Netherlands.
-The terracotta dishes and bases are made in Portugal.
-The glass domes are made in Portugal von recycled glass.
All parts are collected and packaged at the House of Thol headquarters in Overasselt.
Why should I rinse twice a day?
Rinsing twice a day keeps your sprouts fresh and healthy. It removes excess starches released during germination, prevents water from stagnating, and ensures the seeds stay evenly moist — not too wet, not too dry.
This simple rhythm supports steady growth and helps keep the sprouts clean, crisp and pleasant to eat. Morning and evening is usually enough, and it quickly becomes an easy part of your daily routine.
How long does it take to ship the Patina Germina?
Patina Germina will be produced after our Kickstarter campaign, which we plan to launch in February. If the campaign is successful, production will begin shortly after, with shipping of rewards planned for September.
This timeline allows us to produce Patina Germina carefully and at the right scale, using our trusted partners in Portugal. Crowdfunding helps us avoid overproduction and ensures every set is made with the same attention to materials and finish.
We’ll keep all backers closely informed throughout the process, with regular updates along the way.
How many seeds should i use per cycle?
Less than you think!
A good rule of thumb is about a finger’s thickness of dry seeds, spread evenly across the bottom of the bowl. The seeds will expand as they soak and sprout, so avoid piling them up too high.
If you’re new to sprouting, start with a modest amount. After one or two cycles, you’ll quickly get a feel for what works best for your favourite seeds and how dense you like your sprouts.
Sprouting is forgiving: adjusting the amount is part of the process.
where can i get the seeds?
Sprouting seeds are widely available and easy to find. You can buy them from organic food shops, garden centres, seed suppliers or specialised sprouting brands — both online and locally.
To make it even easier, we’re preparing a curated list of trusted seed suppliers, organised by country. This way, you can find good-quality seeds wherever you are, without having to search endlessly.
We’ll share this list on our website and update it over time as we discover new suppliers.
Where should i place the Patina Germina?
Place Patina Germina somewhere at room temperature, out of direct sunlight and away from heat sources. A kitchen counter works perfectly.
We recommend keeping it close to the sink. This makes rinsing and draining quick and effortless — and helps the sprouting routine fit naturally into your day.
In short: choose a calm spot that’s easy to reach and easy to care for.
Why do you advice against placing the Patina Germina in direct sunlight?
Direct sunlight can overheat the glass and dry out the seeds. Indirect light and room temperature create better conditions for steady growth.
Can i use the Patina Germina without direct light?
Yes. Sprouts don’t need direct light to grow. In fact, many varieties sprout perfectly well in indirect light or even in low-light conditions.
As long as the temperature is moderate and the seeds are rinsed regularly, Patina Germina will work just fine without direct sunlight. For sprouts that prefer darkness, you can also use the cover during the growth.
What is the ideal temperature to grow sprouts?
Most sprouts grow best at normal room temperature, roughly between 18–22 °C (65–72 °F). This range provides stable, gentle conditions that allow seeds to sprout evenly and reliably.
Temperatures that are much higher can cause seeds to dry out too quickly, while cooler conditions may slow down the process. In most homes, no special adjustments are needed — Patina Germina is designed to work with everyday indoor temperatures.
Can i use different seeds mixed together?
Yes, you can. Mixing seeds is a great way to experiment with different flavours and textures. Many sprouts grow well together and create interesting combinations.
That said, it works best to mix seeds with similar soaking and sprouting times. Seeds that grow at roughly the same speed will develop more evenly and be ready to harvest at the same time.
If you’re just starting out, try a single variety first. Once you’re comfortable with the process, mixing seeds is an easy next step.
Can I just use regular water to grow sprouts?
Yes. Regular tap water is perfectly fine for growing sprouts with Patina Germina. There’s no need for filtered or special water.
If your tap water is heavily chlorinated or has a strong smell, you may prefer to let it stand for a short while before using it. But in most homes, ordinary tap water works just as well.
What if I forget to rinse once?
No problem. Missing a rinse once in a while won’t ruin a batch. Simply continue with the next rinse as usual.
Sprouting is a forgiving process, and Patina Germina is designed to fit into everyday life — not to demand perfection. As long as you rinse regularly overall, your sprouts will grow just fine.
Do I need to add fertilizer to my water?
No. Sprouts don’t need any fertilizer. Everything the seed needs to grow is already stored inside it.
Adding fertilizer can actually do more harm than good. Clean water, regular rinsing and a stable environment are all that’s required.
How often do I need to clean my Patina sprouting set?
We recommend cleaning Patina Germina after each growing cycle. Once you’ve harvested your sprouts, simply rinse all parts with warm water and, if needed, a mild dish soap.
Because Patina Germina is made from glass and glazed terracotta, it’s easy to clean and doesn’t absorb odours or flavours. Let all parts dry before starting a new batch.
Does Patina Germina smell?
No. When used as intended, Patina Germina does not smell unpleasant. Fresh sprouts have a mild, clean, slightly vegetal scent.
If you ever notice a strong or unpleasant smell, it usually means the sprouts have stayed too wet or haven’t been rinsed regularly. A quick rinse and normal use will restore balance.
In short: clean water, a simple routine, and Patina Germina stays fresh.
How do I harvest my sprouts?
Once your sprouts have reached the size you like, you can simply place the glass bowl upside down in the dish and eat the sprouts directly from the set.
Of course, you can also take the sprouts out and enjoy them however you like — on their own, mixed into a salad, or added to a meal.
If you don’t use all the sprouts at once, you can place the entire Patina Germina in the refrigerator to slow down further growth and keep them fresh a little longer.
Can I eat the seed hulls?
Yes. Seed hulls are completely edible and harmless. During sprouting, the outer skin of the seed often loosens and may separate from the sprout — this is a natural part of the process.
Some people prefer to rinse them away for texture or taste, while others simply eat them along with the sprouts. Both are perfectly fine. It’s a matter of personal preference.
How should I care for my Patina Germina set?
Patina Germina is designed for everyday use and easy care. After each growing cycle, rinse all parts with warm water and, if needed, a mild dish soap. Because the set is made from glass and glazed terracotta, it won’t absorb odours or flavours.
Let all parts dry before starting a new batch. When not in use, store the set in a dry place. With normal care, Patina Germina will last for many growing cycles.
What if I break or lose a part?
Patina Germina is designed as a simple, modular set. If a part breaks or gets lost, it doesn’t mean the whole set is unusable.
We’re working on making individual replacement parts available once Patina Germina is in production. This allows you to replace only what’s needed, instead of buying a completely new set.
If something happens in the meantime, feel free to reach out — we’re always happy to think along.
Will the color of the terracotta dish fade?
Yes, the color of terracotta can fade over time due to exposure to sunlight, water, and other environmental factors.
With prolonged exposure to sunlight, terracotta can lighten and become less vibrant in color. However, some people actually prefer the weathered and aged look of faded terracotta as it can add character and charm to the piece.
To minimize fading, it's recommended to keep terracotta away from direct sunlight and to avoid using harsh chemicals during cleaning.
Can the Patina Germina be used as a business gift?
Yes. Patina Germina works very well as a business gift, especially for organisations that value sustainability, wellbeing and thoughtful design.
It’s a functional object that invites everyday use, rather than something that ends up stored away. The set is durable, easy to use and encourages a small, positive daily ritual — making it suitable for offices, teams or long-term relationships.
If you’re interested in larger quantities or gifting options, feel free to get in touch and we can explore the possibilities together.
Can i sell the Patina Germina in my shop?
Yes — we’d love that. Patina Germina is designed with retail in mind and works well in shops that value thoughtful design, everyday functionality and sustainable living.
At the moment, we’re preparing the product launch via Kickstarter. Once the campaign is complete and production is underway, we’ll start exploring wholesale opportunities with selected retailers.
If you’re interested in stocking Patina Germina, feel free to get in touch or sign up for our newsletter. We’ll keep you informed as soon as wholesale options become available.
Frequently Asked Questions
About growing sprouts
What are sprouts?
Sprouts are young plants grown from seeds that have just begun to germinate. They’re harvested at a very early stage — usually just a few days after soaking — when the seed has released the nutrients it needs to grow.
Because they’re harvested so early, sprouts are fresh, crisp and naturally nutrient-dense. They can be eaten raw or added to salads, sandwiches and warm dishes for extra texture and flavour.
What is the difference between sprouts and microgreens?
The difference between sprouts and microgreens lies mainly in how long they grow and when they are harvested.
Sprouts are harvested very early, usually after just a few days. They are grown from soaked seeds and eaten whole, at the moment the seed has just begun to germinate. Sprouts are quick, compact and require very little time or space.
Microgreens grow a little longer. They are harvested once the first leaves have developed, giving them a more pronounced flavour and texture. With Patella Crescenda, microgreens are grown on water and can also be eaten root and all, just like sprouts — only at a later stage of growth.
In short: sprouts and microgreens are different moments in the same growing process — both fresh, nutrient-rich, and grown close to home.
Why should I eat sprouts?
Sprouts are a simple way to add freshness and nutrition to everyday meals. During germination, seeds unlock nutrients, making sprouts naturally rich in vitamins, minerals and enzymes — all in a very compact form.
They’re also quick to grow, versatile in the kitchen and easy to use. Whether added to salads, sandwiches or warm dishes, sprouts bring texture, flavour and a fresh, just-grown feeling to your food.
Most of all, eating homegrown sprouts helps bring you a little closer to what you eat — something small, but meaningful.
How long does it take to grow sprouts?
Most sprouts are ready to eat in about 3–4 days. The exact timing depends on the type of seed and the room temperature, but growth is generally fast and visible from day one.
That quick turnaround is part of what makes sprouts so easy to grow — you don’t need to plan far ahead to enjoy something fresh.
Which sprout is best?
There isn’t one single “best” sprout — it depends on what you enjoy eating and how you like to grow.
For Patina Germina, medium-sized seeds work especially well. If you’re just starting out, mung beans, lentils, chickpeas or peas are great choices. They’re easy to handle, sprout reliably and produce satisfying, crunchy results.
Once you’re familiar with the process, you can experiment with other seeds and flavour profiles. Discovering what you like best is part of the fun of sprouting.
Can you use all seeds to create sprouts?
No. Only edible seeds intended for consumption should be used for sprouting. Not all seeds are suitable, and some are simply not meant to be eaten in their sprouted form.
Seeds from the nightshade family — such as tomato, aubergine or pepper — are not suitable for sprouting, as they can contain compounds that are unpleasant or unsafe to eat at this stage.
For best results, choose seeds that are sold specifically for sprouting or food use. Medium-sized edible seeds work especially well with Patina Germina and sprout reliably.
When in doubt, keep it simple and stick to seeds known for sprouting.
Which seeds work best for sprouts, microgreens, or both?
It depends on seed size, growth speed and how the plant develops. Some seeds are best enjoyed very young as sprouts, others shine when grown a little longer as microgreens — and some work beautifully in both stages.
Best seeds for sprouts
These seeds sprout quickly and are typically eaten whole after just a few days:
Mung beans
Lentils
Chickpeas
Peas
Adzuki beans
They’re reliable, easy to handle and well-suited to sprouting methods like Patina Germina.
Best seeds for microgreens
These seeds benefit from a longer growing time and develop more flavour and structure once leaves appear:
Garden Cress
Sunflower
Beetroot
Mustard
They’re ideal for growing as microgreens, including on water-based systems like Patella Crescenda.
Seeds that work well for both
Some seeds can be enjoyed at different stages of growth, depending on when you harvest them:
Peas (young sprouts or leafy shoots)
Radish (sprout or microgreen stage)
Mustard (sprout or microgreen stage)
Sprouts and microgreens are simply different moments in the same growing process — choosing when to harvest shapes flavour, texture and use.
Can you hit me up with some recipes?
Working on it!
Are sprouting seeds expensive?
No. Sprouting seeds are generally very affordable, especially compared to buying fresh sprouts regularly. A small amount of seeds can produce multiple batches, making sprouting a cost-effective way to add fresh greens to your meals.
Because sprouts grow quickly and require very little space or equipment, the ongoing cost stays low. In practice, a bag of sprouting seeds often lasts much longer than you’d expect.
What is the best time to harvest sprouts?
The best time to harvest sprouts is when they look and feel good to you. For most varieties, this is after about 3–4 days, once they’ve developed small shoots and a fresh, crisp appearance.
Some people prefer very young, delicate sprouts, while others like them slightly more developed. There’s no single perfect moment — harvesting is flexible and part of the experience.
What is the best way to store sprouts after harvesting?
If you don’t eat all your sprouts right away, you can store them in the refrigerator to slow down further growth. Simply place the harvested sprouts — or the entire Patina Germina set — in the fridge.
Stored this way, sprouts usually stay fresh for a few days. For best flavour and texture, we recommend enjoying them as fresh as possible.
are homegrown sprouts more nutritious than store bought sprouts?
Homegrown sprouts aren’t necessarily more nutritious by definition, but they are fresher — and that matters. Sprouts begin to lose nutrients over time, so eating them shortly after harvesting helps retain their nutritional value.
Growing sprouts at home also gives you full control over freshness, timing and handling. You harvest and eat them at their peak, without transport or long storage in between.
In short: it’s not about outperforming store-bought sprouts, but about enjoying them at their freshest.
What are the best sprouts to eat to boost my immune system?
Many sprouts contain nutrients that play a role in supporting the normal function of the immune system. Rather than one single “best” sprout, it’s the variety and freshness that matter most.
Sprouts commonly associated with immune-supporting nutrients include:
Mung bean sprouts – a good source of vitamin C and antioxidants
Lentil sprouts – provide plant protein, iron and zinc
Pea sprouts – contain vitamins and phytonutrients
Radish or mustard sprouts – known for their pungent compounds and antioxidants
Because sprouts are eaten very fresh, they help retain nutrients that can degrade over time in stored foods.
A mix of different sprouts, eaten regularly as part of a varied diet, is a simple way to support your body — without relying on supplements or single “miracle” ingredients.
Which sprouts are the best source of vitamin A?
Sprouts don’t usually contain large amounts of vitamin A in its active form. Instead, they provide provitamin A carotenoids (such as beta-carotene), which the body can convert into vitamin A.
Among commonly eaten sprouts, those that tend to contain higher levels of provitamin A carotenoids include:
Pea sprouts
Mung bean sprouts
Alfalfa sprouts
That said, vitamin A levels are generally higher once leaves develop. So if vitamin A is a priority, microgreens (grown a little longer) are typically a richer source than very young sprouts.
In practice, sprouts contribute to vitamin A intake as part of a varied, fresh diet, rather than being a single standout source.
Which sprouts are the best source of vitamin B?
Sprouts are a good source of several B vitamins, especially because germination activates the seed’s metabolism. Different sprouts contain different B vitamins, so variety matters more than choosing a single “best” one.
Sprouts that are commonly noted for their B-vitamin content include:
Lentil sprouts – a good source of folate (vitamin B9)
Chickpea sprouts – contain several B vitamins, including B6 and folate
Mung bean sprouts – provide B vitamins such as B1, B2 and folate
Adzuki bean sprouts – contribute B vitamins and plant protein
Sprouting can increase the availability of B vitamins compared to dry seeds, and because sprouts are eaten fresh, these water-soluble vitamins are well preserved.
As with most nutrients, eating a mix of different sprouts is the best way to benefit from the full range of B vitamins.
Which sprouts are the best source of vitamin C?
Vitamin C levels tend to increase during sprouting, especially compared to dry seeds. Among commonly eaten sprouts, those that are often noted for their higher vitamin C content include:
Mung bean sprouts
Lentil sprouts
Pea sprouts
Chickpea sprouts
That said, vitamin C levels can vary depending on the seed, growing conditions and how fresh the sprouts are. Because vitamin C is sensitive to time and storage, eating sprouts shortly after harvesting helps preserve the most benefit.
As with most nutrients, sprouts contribute best to vitamin C intake as part of a varied diet, rather than as a single main source.
Which sprouts are the best source of vitamin E?
Vitamin E is mainly found in fat-rich seeds, so sprouts made from those seeds tend to contain more vitamin E than others.
Among commonly eaten sprouts, the better sources of vitamin E include:
Sunflower sprouts
Wheat sprouts (wheatgrass at a very young stage)
Alfalfa sprouts (in smaller amounts)
That said, vitamin E levels in sprouts are generally moderate rather than high. As plants grow and develop leaves, vitamin E content usually increases — which means microgreens are typically a richer source than very young sprouts.
In practice, sprouts contribute to vitamin E intake as part of a varied, fresh diet, rather than being a primary source on their own.
Which sprouts are the best source of vitamin K?
Vitamin K is mainly found in green leafy tissues, so its levels increase as a plant develops leaves. Very young sprouts contain some vitamin K, but amounts are generally modest.
Among commonly eaten sprouts, those that tend to contain more vitamin K than others include:
Pea sprouts
Mung bean sprouts
Alfalfa sprouts
That said, vitamin K levels rise significantly once leaves form. For this reason, microgreens are typically a much richer source of vitamin K than very young sprouts.
In practice, sprouts can contribute to vitamin K intake, but they work best as part of a varied diet that also includes leafy greens.
Which sprouts can help battle inflammation?
Some sprouts contain antioxidants and bioactive plant compounds that are associated with supporting the body’s natural inflammatory response. Rather than one single “anti-inflammatory” sprout, it’s the combination of variety and freshness that matters most.
Sprouts often mentioned in research for their antioxidant or bioactive compounds include:
Radish sprouts – contain naturally occurring pungent compounds
Mustard sprouts – known for glucosinolate-related compounds
Pea sprouts – provide antioxidants and phytonutrients
Lentil sprouts – contain polyphenols and plant compounds
Sprouting can increase the availability of certain compounds compared to dry seeds, and eating sprouts fresh helps preserve these benefits.
It’s important to see sprouts as part of a broader, balanced diet. They don’t act as medicine, but they can be a simple, everyday way to add plant diversity and freshness to your meals.
Are sprouts beneficial for people with cancer?
You may come across claims online suggesting that certain sprouts are “good for cancer” or can help during cancer treatment.
These claims usually stem from scientific research into specific plant compounds, not from evidence that sprouts themselves treat or cure cancer.
Some sprouts — particularly those from cruciferous plants — contain bioactive compounds that are being studied for how they interact with processes in the body, such as antioxidant activity and cell regulation. Because these compounds can be present in higher concentrations during sprouting, sprouts are often used in research settings.
However, it’s important to be clear about what this means, and what it doesn’t.
Sprouts are not a treatment, not a cure, and not a replacement for medical care.
Research does not support using sprouts as a medical intervention.
Any potential benefit relates to long-term dietary patterns, not to individual foods acting on their own.
For people undergoing cancer treatment, food choices can be complex.
Immune status, food safety and individual nutritional needs all matter, which is why why dietary decisions should always be discussed with a healthcare professional.
In short: sprouts can be part of a balanced, plant-rich diet, but they should never be seen as medicine.
We believe it’s important to approach this topic with care, nuance and respect for medical guidance.
can I move sprouted seeds to soil?
Yes, you can. Sprouted seeds can be transferred to soil if you’d like to let them grow further into young plants or greens.
That said, sprouts grown with Patina Germina are intended to be harvested and eaten at an early stage. Once seeds have sprouted, their delicate roots can be sensitive, so transplanting works best when done gently and soon after sprouting.
If you enjoy experimenting, moving sprouts to soil can be a nice way to explore the next stage of growth. If not, harvesting them as sprouts is perfectly fine — both options are valid.
what is the best season to grow sprouts indoors?
Sprouts can be grown all year round. Because they don’t rely on sunlight, soil or outdoor conditions, the seasons don’t play a big role.
As long as your home is at a comfortable room temperature, sprouting works just as well in winter as it does in summer. In colder months, sprouts are a nice way to add something fresh and green to everyday meals; in warmer months, you may just want to keep them out of direct sun and excessive heat.
In short: if you’re indoors, it’s always sprouting season.
is growing sprouts indoors beneficial for your living environment?
Yes, growing microgreens indoors can be beneficial for your living environment in a number of ways.
Firstly, microgreens can help purify the air by removing pollutants and harmful chemicals.
They can also help regulate humidity levels in your home, which can prevent the growth of mold and other allergens.
Additionally, growing microgreens indoors can provide a source of fresh, nutritious produce, which can help improve your overall health and wellbeing.
Finally, tending to indoor plants and microgreens can have a calming effect, reducing stress levels and promoting a more relaxed living environment.
How do microgreens contribute to a resilient and future-proof world?
Microgreens can contribute to a more sustainable and future-proof world in several ways:
- Efficient use of resources: Microgreens can be grown with minimal space, water, and fertilizer, making them a more sustainable alternative to traditional agriculture.
- Reduced food waste: Microgreens have a shorter growing cycle than mature plants, so they can be harvested and sold more quickly, reducing the risk of spoilage and waste.
- Local food production: Growing microgreens can be done year-round and in urban areas, allowing for local food production and reducing the carbon footprint associated with long-distance transportation.
- Health benefits: Microgreens are packed with nutrients, making them a healthy addition to any diet. They can be used to supplement meals, adding flavor and nutrition to a range of dishes.
Overall, incorporating microgreens into our diets and supporting local, sustainable food production can help build a more resilient and future-proof food system.
Why is eating microgreens sustainable?
Eating microgreens is considered sustainable for several reasons.
Firstly, microgreens can be grown year-round in a small space, without the need for large amounts of water, fertilizer, or pesticides. This means that they can be grown locally, reducing transportation emissions and the carbon footprint associated with the production and distribution of food.
Additionally, microgreens are a highly efficient crop, as they can produce a large amount of nutritious food in a small area. They also have a quick growth cycle, typically taking only a few weeks to mature, which means that they can be produced and harvested more frequently than many other crops.
Finally, microgreens are highly nutritious, containing high levels of vitamins, minerals, and antioxidants. This means that they can provide a sustainable and healthy source of food for people, which is important for promoting overall health and wellbeing.
