Research-driven art and design collective working in the realm of social dreaming and world-making. Our projects engage with the nonhuman: animals, objects, ecology, technology, and the spectres between and beyond categories.
We see nonsense as an antidote to “common sense” – embracing paradoxical stories to explore the ethical and metaphysical layers of our relationship with the (nonhuman) world. We create contradictory scenarios & propositions in which we appropriate ideas from fields such as science, computing, law and mythology. Our projects take various forms - interactive installations, workshops, short films, public sculptures, campaigns, chatbots and books. 
We enjoy curiosity, cherish compassion, and recognize that separating the human from the nonhuman is nonsense.

My 15 years in Horticutlrue have been paved with enormus passion for growing plants. It's been an ongoing jurney, from managing tree nursery production in continental climate in Bosnia, to overseeing hi-tech vegetable production in the Omani desert, my experiences have been very rewarding and uplifting. 
Without neglecting my main passion, growing, I’ve developed into substrate industry consultancy, drawing inspiration from the stunning Nordic landscapes. My passion lies in helping fellow growers optimize their crop performance by analyzing their crop data set and selecting the ideal growing media solution.
Last years I've put my energy and focus into helping growers transition easily into new future and start learning about new generation of growing media.  
I’m grateful for the opportunity to share experiences and consult with various growers across the globe. Not only with the growers who use high tech facilities, but also with the ones that are just staring to enter soiless growing practices.
From North American leafy greens and ornamental growers to Chinese blueberry growers in Yunnan, I do my best to help them choose the optimal substrate solution and use their crop resources in the best way.

Senior Manager - Strategic Development

As a biologist, Johanna Bac-Molenaar is inspired by the nature around her. She is fascinated by the wondrous processes that ensure that inanimate things come to life. During her studies in biology and in her PhD research, she specialized in the study of plants and their interaction with the environment. She currently works as a 'Plant Health' researcher at the Greenhouse Horticulture business unit of Wageningen University and Research. Strengthening the plant's natural defenses against diseases and pests is central to many of her projects. Because she is involved in many strawberry projects, she also became a specialist in strawberry cultivation. Cultivation choices, such as type of substrate, fertilization, irrigation strategy, light spectrum, plant density, influence the natural defenses of the plant. Her goal is to work on resilient cultivation systems where increasing plant resilience is supported by the aforementioned cultivation choices.

The team Rootzone Dynamics from Wageningen University & Research BU Greenhouse Horticulture focuses on investigating processes around the plant roots and in the irrigation system. Research topics: alternative growing media, microbiology, belowground phytopathology, water quality, fertigation and virology. My personal focus has been on the application of water technology to achieve a zero-emission cultivation system with optimal recirculation water quality: prevent distribution of diseases via water, removal of plant protection products from discharge water, optimization of filtration and selective ion removal. Focus is on finding technologies that have specific effects on water quality, without inhibiting plant productivity, for example for prevention of biofilm formation in irrigation lines. The role of water composition and treatment on the rootzone microbiology is another topic that still requires a lot of attention.

Manager Improvement Centre

Feije de Zwart is working in the field of greenhouse horticulture for more than 30 years. He started his work with an PhD from 1989 to 1996 on simulating the greenhouse climate to energy saving perspectives of various techniques in horticulture. This model was built from standard physical relations to describe the physical processes in the greenhouse envelope and includes a complete practical-like greenhouse climate controller. In the period from 1996 till today, this simulation model has been continuously evovolved in its use for ongoing research projects and constantly updated with the newest climate control equipment (especially cooling devices) and the latest insights in greenhouse climate control. In the past years, this model is gradually transformed to an on-line applicable system for all kind of educational and design purposes. In the past decade, his expertise on energy aspects of horticulture has been extended with solar energy and other sorts of sustainable energy. This expertise covers both the theoretical, as the practical aspects of standard solar panels and concentrated solar power.
The last decade, H.F. de Zwart is also involved in a number of international consultancy and demonstration projects (China, Japan, Abu Dhabi, Korea, Saudi-Arabia). The purpose of these projects is to teach local greenhouse managers and researchers on the ins and outs of modern greenhouses and the latest horticultural insights. These projects do not only address climate and energy-issues, but also water and nutrition and crop handling.
In the past years, also the role of horticultural production in the wider perspective of sustainable food supply for urban communities was added to the field of expertise.
The work of H.F. de Zwart is carried out in the framework of consultancy projects and research programs, from which a number are managed by himself. The management qualifications involve the contacts with stakeholders, financers and co-workers.
