Are you looking for quality growing supplies to help you get the most out of your indoor growing?

Whether your goal is to grow herbs, chilies, tomatoes or more specialized plants, we have everything you need in one place - at competitive prices and with fast delivery.
Efficient LED grow lights for indoor growing
One of the most important factors for successful indoor cultivation is the right lighting. In Cropper's selection you will find high-quality LED grow lights that provide your plants with the optimal spectrum for different stages of growth – from germination to flowering. LED lights are energy-efficient, long-lasting and produce less heat than traditional HPS or CFL lamps, which makes them an excellent choice for a grow cabinet or grow tent. We offer, among others, efficient LED lights for spaces of various sizes from the LUMII , Superplant and Grow the Jungle series.
Grow tents that control conditions
A grow tent is every indoor grower's best friend. It allows for precise control of the growing environment in terms of light, humidity and ventilation. Cropper's grow tent range includes both compact tent models aimed at beginners and large growing solutions suitable for professional use. We offer well-known brands such as BlackBoxSilver and Secret Jardin - not forgetting the high-quality construction and reflective interior surface.
Ventilation and odor control – fresh air for plants and your home
Good ventilation is vital for plant health. We offer duct fans , activated carbon filters , ventilation pipes and other ventilation accessories to ensure fresh and clean air in your growing environment. In addition, odor control is easy when you choose the right air purification solutions.
Nutrients, growing media and measuring instruments
Our range includes a carefully curated selection of nutrients that your plants need to grow strong and productive. We also offer a variety of growing media such as coconut fiber, rock wool and solutions suitable for hydroponics. You will also find pH and EC meters, calibration solutions and temperature and humidity meters to accurately monitor growing conditions.

Pre-cultivation and seed treatment – an important step to success
Growing begins even before the actual planting. At Cropper you will also find tools for pre-growing and seed treatment. Properly prepared seeds germinate faster and more evenly, which speeds up the entire process and minimizes failures. Our selection includes seed cubes, pots for seedlings, seedling growth boxes with transparent lids, and hydrogen peroxide, which helps clean seeds of pathogens before sowing.
Hygiene in education – cleanliness prevents problems
Regular cleaning of growing media, pots and systems prevents many problems. Especially in hydroponic systems, it is important to ensure the cleanliness of hoses, tanks and pumps. In addition to hydrogen peroxide, Cropper offers surface disinfectants and tools such as measuring jugs, protective gloves and spray bottles to make disinfection easy and safe.
Maintenance of farming systems – ensure longevity
Whether you use a DWC, NFT, Ebb & Flow system or traditional potting, regular maintenance ensures that your system is working properly. We offer filters, replacement pumps, seals and hose accessories to keep your system in good condition and ready to use. This way, you avoid production interruptions and improve plant health.
Scheduling and automation – easy cultivation management
Optimal plant growth requires regularity. At Cropper, you can get timers and controllers that automate lighting, ventilation and watering. This creates a stable rhythm for your plants and reduces your manual workload. We also offer temperature and humidity controlled relays and smart timers that can be controlled remotely - the perfect choice for the modern grower.

2. Is a tent always needed for breeding?
Not always, but a grow tent makes controlling conditions easier and more efficient, especially in small spaces.
3. Why is ventilation needed in cultivation?
Ventilation removes moisture and heat, provides oxygen to plants, and prevents odors and mold problems.

Yes you can! For example, DWC is an easy option and you can get all the necessary parts ready-made from Cropper.
5. Which growing medium is best for a beginner?
Coconut fiber or pre-soaked rock wool are easy and clean options to get started.
6. When do I need pH and EC meters?
If you use nutrients or hydroponics – meters ensure that your plants are getting the right amounts of nutrients.
7. How often should plants be watered indoors?
It depends on the growing medium and environmental conditions, but watering can be precisely automated with timers.
8. What do I need to control odors?
An activated carbon filter and good ventilation are sufficient for most situations. A clip-on fan helps with air circulation.
