Trials undertaken at the CFC in 2016 and 2017 set out to assess the potential of ornamental grasses as a ‘seasonal filler’ to add structure and bulk to cut flower bouquets.

Trials undertaken at the Cut Flower Centre (CFC) have assessed the potential of two new series of cutting-raised Scabious which have been specifically bred for cut flower production.

Heat pumps take low grade heat from the ground, water or air and boost it to higher temperatures to make it useable for heating. Read part one of this two-part technical update to find out more.

What are the practicalities of installing heat pumps? Read part two of this two-part technical update.

Circulation fans have been widely used in greenhouses for many years. A well designed fan installation will benefit the greenhouse climate by helping to maintain consistent temperature and humidity throughout the growing area.

Screens have become an essential tool for energy saving, shading and climate control in modern protected horticulture. New screen materials which save more heat energy and transmit more light have been developed, enabling screens to be deployed more in the daytime, or in double layers. There has never been a wider range of screen materials to give the optimum balance between energy saving, light transmission and shading. Read more in this technical update.

Energy makes the world go round and it can manifest itself in many forms including radiation, light and chemical. However, we are mostly concerned with it as heat, electricity or as fuel (i.e. oil, gas, wood etc.) which, for the most part we pay for. It’s important that we are able to measure it, so we can evaluate and compare its costs and assess how efficiently it’s being used. Read more about how best to measure your energy use in this technical updates.

Biomass boilers can also enable power generation. This allows simultaneous generation of usable heat and electricity and is known as Biomass Combined Heat and Power (CHP). Read more about this topic in this technical update.

The principles and benefits of diffuse light in greenhouse crops are widely accepted. In this document, we remind ourselves why diffuse light is important, explain how it is measured and the different solutions available to enable this benefit in your greenhouse.

This is the second part of a two-part update on CO2. The first part covered the costs and characteristics of conventional CO2 supply. Here, we look at the supply of CO2 from biomass and anaerobic digestion and discuss how it has developed since the uptake of renewable-based heating systems.

Our Extension of Authorisation for Minor Uses (EAMU) programme for the horticulture industry helps you to remain competitive by ensuring there is access to essential crop protection products.

Early spring impulse sales - extending the product range by forcing herbaceous perennials into flower with minimal inputs

To help characterise the current labour and skills situation in horticulture, AHDB funded two industry skills surveys.

This is part one of a two part update, in which we revisit the conventional sources of CO2 supply and discuss the influence of factors, such as heat requirement and electricity price on the cost attributed to CO2 supply. Conventional sources includes: flue gas from the ‘back of the gas boiler’, LPG or kerosene direct-fired heaters, CHP units or pure CO2 delivered to site.

Sensors are the eyes and ears of your control system and fundamental to its operation. Inaccurate measurements, due to faulty or poorly maintained sensors, can result in wasted energy, substandard crop performance and even increased disease so they are very important. In this technical update, we discuss what to watch out for when choosing and looking after sensors in glasshouses.
