Feedback and support
This is the first course dedicated exclusively to cut hydrangeas. No "water" about general floristry — only the necessary knowledge about hydrangeas. You get exactly what you need to succeed in this niche.
The course was developed in collaboration with a Dutch specialist with 25 years of experience in growing hydrangeas. The Netherlands is a global leader in the flower business, and you will gain access to exclusive technologies that were previously only available to the leading farms in Europe.
The program is structured logically and consistently. Learn step by step — first the basics of biology, then planting, care, and plant protection, and finally harvesting. This format will help you master even complex topics without chaos and apply your knowledge immediately.
You won’t be left alone with the material. Course participants gain access to a closed community of like-minded individuals and experts. They can ask questions, discuss their results, and receive guidance and error analysis. Practical assignments and their verification help to better reinforce skills (advanced course packages offer individual consultations).
You will be able toф review the videos and use the tutorials at any time. Learn at your own pace — whether it’s in the evening after work or on weekends in the country, the content is always at hand, according to the chosen tariff (6, 12, 18 months).
Practical methods that have already yielded results on large flower farms. You will receive a clear care technology, avoid common mistakes and achieve a luxurious bloom even in difficult climatic conditions.

Why You Can Trust Me?
In 2025, I came up with the idea of creating an online school that combines professional expertise with practical technologies tested on real farms across Europe.
At the very least, I’ve been active in the Dutch market for over 15 years and consistently stay up-to-date with the latest developments and innovations in the field. By combining my commercial experience with cultural and linguistic knowledge — and a deep personal connection to the Netherlands — I’m able to create successful projects for my clients and collaborate with top consultants and experts across Europe.
At GreenControl Agro Academy, we have gathered the most essential knowledge for a successful agribusiness. We have transferred the experience of Europe’s best flower and berry growers into clear step-by-step instructions that work in your local conditions.

Frequently Asked Questions
It is suitable for both farmers/greenhouse owners planning commercial production and novice flower growers who dream of mastering a new crop.
No, prior experience is not required. The course starts with basic concepts and gradually progresses to more advanced techniques. We explain the terminology and biological fundamentals, providing everything a beginner needs. However, the course is also valuable for experienced gardeners. If you have already grown hydrangeas or other flowers, you will gain a comprehensive understanding and advanced techniques.
The format is flexible. Officially, the course is designed for 6 weeks of training, but you can go through it at your own pace. All the lessons are already recorded and will be opened sequentially every week (or the entire course at once, depending on the launch format). There is no rigid time binding - you independently plan when to watch lessons and do assignments. Only live Q&A sessions and consultations (for those packages where provided) take place in real time, but their attendance is optional, plus they are recorded. This way, even if you work full-time, you can easily make time for study in the evening or on the weekend. Many of our students combine the course with their main job or current business.
It’s very simple: you leave an application on the website and pay for participation in the selected package. Within a few minutes, you will receive access to our educational platform (login and password for your personal account). No additional software is required; you only need a modern browser. All purchased materials will be available on the platform, including video tutorials, files, links to webinars, and more. You can access your account from any device. If you choose a package with consultations, the manager will contact you to agree on a convenient time for a call with the expert. The materials for the introductory lessons will become available immediately after payment.
Yes, of course! Student support is one of our top priorities. In any package, you’ll have access to a private chat room where you can ask questions to your colleagues and experts. We also host live Q&A sessions where we answer the most frequently asked and complex questions (for the Basic and Standard packages, these sessions are held in a general webinar format, while for the Premium and VIP packages, they are held in a one-on-one consultation format). If you have any doubts about the lessons, you can always review the videos or seek clarification. Our experts, including a guest expert from the Netherlands via a translator, are available to help you with any difficulties you may have with the course. We are committed to seeing you through to the end, so we don’t leave our students alone once we’ve provided them with the materials.
No, it is not necessary to have a ready-made infrastructure. The course is equally useful for those who already have a greenhouse farm and those who are just planning to create one. You can first complete the training, learn all the requirements for the greenhouse and planting, and then consciously equip the area for growing hydrangeas. Many students start with a small area, such as a few beds or a greenhouse, and achieve success. Later, by applying the knowledge you have gained, you can scale up to industrial volumes. We will tell you what conditions are optimal for hydrangeas, but we will also provide options for those who do not have a heated greenhouse (for example, they can be grown seasonally in open ground with certain agricultural techniques). You will start with what you have and gradually reach the desired level, and the course will help you achieve this.
