More growers opt to replace old screens

Save even more energy and transmit more light

- Abbey View Nurseries, Waltham Abbey

Like most leading salad growers, Abbey View installed their screens some time ago. After years of constant use, they had become very tired but, like many growers, nursery manager Alan Richardson hesitated for a while before deciding that it was time to renew the system. 'Actually, this should have been done earlier' says Alan, 'but agreeing on the best time to replace an existing asset is never easy'. However, once the decision was made, everything went very smoothly. 'The CMW crew were the best screen contractors we've ever had on site'.
Modern equipment and experienced fitters make for a very efficient refurbishment process. Using a new monofil deployment machine, over 16,000 square metres of monofil were replaced in only 3 days!

 - Ravensworth Nurseries, N.Yorkshire

Glasshouses come in all shapes and sizes, and by no means all have tall stanchions, wide bays and unfettered access.
Ravensworth Nurseries grow a mixture of pot and bedding, mostly on benches, and replacing old screens over a growing crop presented several challenges - not only to carry out the work in a timely manner but also to avoid disruption to day to day operations on the nursery and above all to ensure no damage to the crop.

Co-owner Fiona Dean opted for the Ridder flame retardant material RLD 60FR which provides 60% shade under direct sunlight, 65% shade under diffused light and 48% energy saving. She says 'The refit went very well with very little disruption to our normal operation and no crop damage at all. The new screen is a big improvement on what we had before in every respect.'

Priva management tool is a hit at Cornerways

‘You can’t manage what you can’t measure’ is one of those truisms frequently preached by management gurus. That’s actually very true, but once you get beyond a certain scale, measuring, especially measuring what work people do, can become a very onerous task. And, having measured and collated all the data you need, how do you filter out the bits of information you actually need from the enormous amount of data that’s been gathered?

Year Round production a success at Sandylands

When R&L Holt decided to modernise the Sandylands site where Rick started the family business from scratch over 35 years ago, there were no half measures. Three blocks of old glass, staff facilities and the boiler house were demolished to make way for a 1.13 MW Combined Heat and Power unit, modern staff facilities, offices and a state of the art 8,300 m2 structure fitted with diffused glass and lighting for year round production, all designed and built by turnkey specialists Certhon, who had previously completed greenfield projects for the Holts at their Hornsfield and Springhill sites.

New management information system for Cornerways

When you have 18 hectares of glass and more than 250 pickers and crop workers, keeping up to date with how the whole enterprise is performing in real time is a tremendous challenge.

The management at Cornerways Nursery decided that they needed to be able to gather accurate management information quickly and reliably, so they weighed up all the things that a modern management information system needed to do for them.

Red Roofs Nursery

Turnkey project for Chris Durnford completed on time and on budget

Increasing demand for quality UK grown tomatoes gave Chris Durnford of Red Roofs Nursery in East Yorkshire the confidence to invest in a 700 sq m packhouse and 16,660 sq m of fully fitted new glass with 6 metre posts. The project is the result of close co-operation between Certhon, who took care of the glasshouse and heating, and CMW who supplied and installed all the equipment and managed the whole project.

R & L Holt - Springhill Nurseries

Despite advances in both overhead and side screens, greenhouses have always been susceptible to having a 'cold side'. Cold air above an overhead screen will invariably collect at one gable end and this can result in a lower temperature in the growing area below the screen at the affected end. Uneven temperatures can have a serious impact both on the crop itself and on energy consumption.

MT Mitchell, Castleton Farm

Using VPD (Vapour Pressure Deficit) for improved irrigation control

Originally dairy farmers, the Mitchell family bought Castleton farm in 1992, part of which was a soft fruit crop of 15 acres. In 1999, they decided to stop dairying and increased their soft fruit production.

Eric Wall Ltd

Eric Wall and Hugh Stevenson bought Pollards Nursery back in 1977, in those days with just 2½ acres of existing widespan glass. Formerly a rose unit, the nursery was converted to specialise in tomatoes. Now, 35 years later, the nursery has grown to 28 acres on the original site in Barnham, West Sussex.

Les Halman Nurseries Ltd

The Halman family has a long history in the nursery business, going right back to 1887 when Les's grandparents began market gardening. There have naturally been many changes since, but the family's proud heritage still continues with Les's son Stuart having joined the business in 1995.

Gee Vee Enterprises

Family traditions are strong in the Lea Valley, where you’ll come across more entrepreneurial young growers than any other area in the UK. Gee Vee Enterprises are a case in point. Founded by Gaetano and Vincenzina Cappalonga in 1997, initially as an AYR chrysanthemum unit, Netherhall Nursery switched to peppers in 1999 and were joined in the business by their forward looking son John in 2006.John has been the driving force behind an investment of £1.5 M in new glass, with integrated packhouse and office.

Coletta & Tyson

Coletta & Tyson, one of Europe’s largest specialist independent producers of ornamental plants, is a vast operation by any standards – with nurseries on several sites in East Yorkshire covering 162 Ha in total, producing 100 Million plants a year.

Pipe welding solves water main problem

Fusion welding HDPE pipe

Standard practice in UK horticulture has always been to joint PVC pipes with unions or glued joints. If the pipes are underground and a joint fails, there will be considerable disruption, inconvenience and potentially crop loss. Using HDPE (High Density Poly Ethylene) pipe rather than PVC introduces the possibility of creating extra strong joints by welding two ends together under heat and pressure to form a continuous pipe.

Kevin Hobson reduces his spraying costs by 66%

Crop spraying is one of the most critical, expensive and time consuming processes for any horticultural business. The CMW spray robot not only ensures accurate, uniform application of the pesticide, but considerably speeds up the process. Grower Kevin Hobson of East End Nurseries comments on his experience with the spray robot in the PDF below.
