If you’re serious about hydroponics, controlled-environment agriculture, or greenhouse growing, planning ahead matters. From photoperiod-changing calendar dates to international trade shows, knowing what’s coming up in 2026 can help you avoid mistakes, budget properly, and make the most of networking opportunities.
In this blog we highlight the key diary dates and industry events hydroponic growers should be aware of in 2026.
Even in soilless systems, seasonal light and temperature changes still influence plant growth — especially in greenhouses and polytunnels.
These dates affect:
For fully indoor grow rooms, these dates matter less — although summer heat still creates challenges for temperature control.
If you’re new to indoor hydroponics, January is ideal:
By contrast, summer mistakes are far less forgiving; high temperatures can quickly kill crops if systems fail.
📅 27–30 January 2026
📍 Essen, Germany
One of the world’s biggest ornamental horticulture shows. Ideal for:
Germany is cold in January, plan accordingly, but transport links and organisation are excellent.

📍 Berlin, Germany
Still one of the largest global fruit (and increasingly vegetable) trade shows, despite growing competition from Madrid. Best for:
📅 11–12 February 2026
📍 Las Vegas, USA
A vertical farming and indoor agriculture-focused event. Particularly relevant for:
📅 9–11 June 2026
📍 Amsterdam, Netherlands
One of the must-attend events for anyone in hydroponics, greenhouse growing, or polytunnels.
Why it stands out:
If you only attend one hydroponics trade show in Europe, this is it.

Known for its diverse grower base, including Amish growers, it offers a very different perspective on commercial horticulture.
Events such as:
These can be hit or miss depending on location and budget. MJBizCon in particular is a pay-to-play show and best suited to well-established operators with significant resources.
There are always additional niche events worth watching for, including:
These smaller shows can often provide higher-quality technical insight than large commercial expos.
Hydroponics is a fast-moving industry, and early planning gives you an advantage; whether that’s better growing outcomes, smarter investments, or stronger industry connections.
Adding these dates to your 2026 diary now allows you to:
If new trade shows or conferences appear, this list can always be updated; but this is a solid foundation for any hydroponic grower planning ahead.
