Spring marks one of the busiest and most rewarding times at In Vitro S.L.—the culmination of months of precise laboratory work, greenhouse care, and logistical coordination. Each year, hundreds of thousands of Paulownia Clone InVitro 112® plants leave our facilities to reach clients across Europe and beyond.

Precision in Propagation

Every batch we ship has been produced under our strict in vitro micropropagation protocol, ensuring perfect genetic identity, sanitary, and traceability guarantees. Each plant passes through controlled growth phases: laboratory, acclimatization, and hardening.
Only after meeting our internal quality parameters—root density, uniformity, and vigor—do the plants enter the delivery queue.

Packaging with Purpose

Before shipment, plants are inspected and packed with the utmost care to maintain their humidity and health throughout transit. Our specialized packaging protects the roots and shoots while allowing for aeration. 

We offer two formats to adapt to the client’s needs:

• 🌱 Paulownia clon invitro 112® Ready-to-Plant (ready to plant immediately upon receipt)
• 🪴Paulownia clon invitro 112® 60-cell Alveolus (can be planted directly under certain conditions or transplanted in bigger pot and housed in greenhouse before planting for 1-2 months in warm weather)

Global Coordination

Shipments are organized according to each country’s optimal planting calendar. For most of Europe—Germany, France, Poland, and the Netherlands—spring offers ideal temperature conditions.
By coordinating production cycles with planting windows, we guarantee that our partners receive trees in their best physiological state, synchronized with local climates.

Commitment Beyond Delivery

Our service does not end once the truck departs. We are at the disposition of each client to provide him with technical assistance to ensure the success of his plantations and the completion of their cultivation objectives.
This dedication has made In Vitro S.L. a trusted partner in agroforestry, biomass, and carbon-offset projects worldwide.

As we complete this year’s deliveries, we’re already propagating the next generation for autumn and spring planting seasons. The cycle never stops—it evolves with every new partnership and plantation.
