Hydrogen peroxide use spring 2025 – clean water for wells and better growth for crops
Share
Hello Cropper Protips readers and happy Friday! Friday and the beginning of the weekend, any free time coming up? So it's a good time to focus on cleaning wells with hydrogen peroxide!
Spring is a time of renewal – in nature, in the garden and in water management. Many Finns start spring by checking the condition of their wells and cleaning their water systems after the winter. At the same time, pot growers, hydroponics and greenhouse enthusiasts are preparing to grow a new crop. There is one really effective and easy solution for both needs: hydrogen peroxide .
In this Cropper ProTips article, we explain why hydrogen peroxide is the most important adjuvant of spring 2025 – whether it's for well cleaning , aquaculture , pot growing or general disinfection . We provide practical tips, dosage instructions and warnings, and tell you where to easily buy hydrogen peroxide in Finland .
What is hydrogen peroxide?
Hydrogen peroxide (H₂O₂) is an odorless, colorless liquid with a strong oxidizing effect. It consists of hydrogen and oxygen, and after use it breaks down into just water and oxygen – leaving behind a clean environment. This makes it a very popular option for cleaning wells , disinfecting growing media , and oxygenating roots in aquaculture .
12% hydrogen peroxide is an effective yet suitable solution for home use. Cropper offers products with this concentration, which are especially suitable for the needs of growers and cottagers.
Hydrogen peroxide in well cleaning
One of the most common uses in the spring is for hydrogen peroxide for well cleaning . During the winter, well water can become contaminated with microbes, algae, organic residues or even microorganisms that reduce the quality and safety of the water. Untreated well water can cause stomach symptoms or even illness at worst.
How is hydrogen peroxide used to clean a well?
-
Partially drain the well to prevent the water from becoming too diluted.
-
Add hydrogen peroxide according to the volume of the well . The general guideline is:
-
1 liter of 12% hydrogen peroxide / 1000 liters of water
-
-
Leave for at least 12 hours – preferably overnight.
-
Pump water from the tap or hose so that the substance also spreads into the pipes.
-
Rinse the well with clean water before use.
Cropper's Hydrogen Peroxide 12% is excellent for this purpose – a safe and effective way to restore water quality without the side effects of chlorine.
Hydrogen peroxide in plant growth
Hydrogen peroxide isn't just for water purification – it's also a surprisingly effective tool in potting and aquaculture .
Benefits of aquaculture:
-
Increases the amount of oxygen in the root system , which promotes plant growth and nutrient absorption.
-
Fights bacteria and fungi that cause root rot and other problems.
-
Disinfects growing media and equipment without toxic residues.
Dosage for plants:
-
For maintenance : 2–3 ml of hydrogen peroxide (12%) per liter of water, 1–2 times a week.
-
For disinfection : 5 ml per liter of water for short-term use.
-
Used in irrigation water or aquaculture systems.
Remember that dosage is important – too much can damage the plant roots.
Hydrogen peroxide for home and garden disinfection
Hydrogen peroxide also works as an effective and environmentally friendly disinfectant in other areas:
-
Tools and equipment (from scissors to pots)
-
Water pumps and hoses
-
Hands, door handles and surfaces
It kills bacteria and viruses without odor or residue, making it a versatile product, especially for spring cleaning and preparing for the cottage season .
Where to buy hydrogen peroxide?
One of the most common Google searches is “where to buy hydrogen peroxide?” and no wonder. Many brick-and-mortar stores no longer stock 12% products, and pharmacies often only stock 3% strengths. Luckily, there’s an online solution.

Hydrogen peroxide vs. chlorine – which is better?
Traditionally, wells have been cleaned with chlorine, but more and more people are choosing hydrogen peroxide because:
-
It does not leave a pungent odor or taste
-
It breaks down naturally , leaving behind only water and oxygen.
-
It is gentler on the plumbing and nature
Chlorine residues can irritate the skin and respiratory tract, while hydrogen peroxide is safe when used in the correct dosage .

Hydrogen peroxide in practice – experiences and tips from users
Many Cropper customers have made hydrogen peroxide a part of their spring cleaning routine, and for good reason. Experience has confirmed its versatility and effectiveness. Customers have particularly praised the fact that hydrogen peroxide does not cause side effects like chlorine – no irritating odor, no metal precipitation, and no change in the taste of the water. This makes it a particularly popular option for cleaning small and medium-sized ring and borehole wells .
Many people also use hydrogen peroxide for preventative well maintenance , adding small amounts to the well a few times a year, especially in the spring and fall. This can help prevent algae and microbial growth in advance, making the water quality more consistent and cleaner throughout the season.
Gardeners have also reported that seedlings watered with hydrogen peroxide start growing faster as the root system receives more oxygen right from the start. This is especially important in coco coir and other aerated growing media , where the balance of water and oxygen is crucial for root health.
Frequently Asked Questions About Hydrogen Peroxide
Is hydrogen peroxide safe to use at home?
Yes, as long as you follow the instructions. 12% hydrogen peroxide is strong, so you should use protective gloves and be careful not to get it in your eyes. However, when used correctly, it is very safe – and leaves no harmful residue.
Can I use the same hydrogen peroxide for both the well and the plants?
Yes, you can. Cropper's 12% hydrogen peroxide is a multi-purpose technical grade that is suitable for both water treatment and plant root care. The most important thing is to dose correctly – more for the well, less for the plants.
How is hydrogen peroxide different from the 3% products in the pharmacy?
The 12% concentration is significantly more effective and is better suited for disinfecting wells, for example. The 3% products from the pharmacy are mild and often packaged in small bottles, which are not practical for larger applications. Cropper's products are cheaper per liter and more effective .
Can I use hydrogen peroxide on houseplants?
Yes! Many people use a mild hydrogen peroxide solution in their irrigation water to revitalize the root system and prevent fungal infections. For example, moldy soil surfaces and poorly breathing pots benefit from a little extra oxygen.
Hydrogen peroxide and the environment
One of the biggest advantages of hydrogen peroxide is its environmental friendliness . Unlike many synthetic cleaning agents, hydrogen peroxide does not accumulate in the environment and does not harm waterways or soil. After use, it breaks down into just oxygen and water – without toxic byproducts. This makes it an ideal choice for environmentally conscious consumers and homeowners who want to clean responsibly.
Hydrogen peroxide also does not require separate waste management measures, and it is easy to store in a closed container in a cool, dark place. This means that one product can serve multiple purposes throughout the growing season.
