Total area for cultivation of vegetables is ~30.218 m² and a service-building of ~1.679 m². - assumed project altitude : 1.050 - 2.340 m. In these greenhouses we offer you the delivery of:

- a service area (with a heating room and irrigation room); - a greenhouse computer control system - a complete heating system with CO2-dosing, running on natural gas

(in emergency situations light oil will be used as fuel); - a complete irrigation system (hydroponics); - a complete screening system (energy saving and shadow); - a lighting system for young plant area; - a steel hanging gutter system; - internal transport - tomato grader installation - cold store - tomato seeds - fertilizers - pesticides - emergency power unit - ‘Georgia’ spray cart - high wire hooks - assembly and construction works - finally we offer you supervision during construction.

The supply of the inside Zeus dollies for the foundation is included in this offer. For the perimeter foundation we do include foundation drawings and the services of a supervisor.

We do supply the materials Free Carrier Gemeente Westland, The Netherlands, according Incoterms 2010-edition.The materials will be loaded in trucks or containers. Packing as commonly known in shipping glasshouse materials and according to the general conditions known for sea or truck freight. The production and construction of our greenhouses takes place according to BRL 8000 for which a Horti-Q certificate was received. We work according to the quality standards of the Horti-Q Quality system given by the foundation of recognition of Dutch greenhousebuilders. HORTI Q Why certification? Greenhouse horticulture worldwide and in The Netherlands is making enormous leaps in development, both in terms of scale and in terms of the complexity of the equipment. Developments in the areas of energy, heat storage, robotics and climate technology – to name but a handful of current issues – have created the need for a more transparent quality system. The grower therefore wants to be certain that his greenhouse and equipment have been designed and built to objective standards. The HortiQ certificate offers this assurance! This is also the reason why the HortiQ quality system is supported by important players in the market such as:

• The Netherlands Ministry of Agriculture, Nature Management and Food Quality

• AVAG – Forum for Suppliers to Greenhouse Horticulture

• Interpolis (insurance company)

• OVTO – Organisation of Horticultural Consultants and Researchers

• ABN AMRO

Alongside the knowledge institutions like TNO and the industry itself, these players have made an active contribution to the development of the HortiQ quality system. How does HortiQ certification work? HortiQ uses two assessment guidelines (BRL):

• BRL8000 “product / process certificate”: assessment of the general quality policy (“process”)

and the greenhouses and / or equipment supplied (“product”) on the basis of one of the

three quality guidelines

• BRL8001 “quality system certificate”: assessment of the general quality policy (for

companies whose products are not covered by one of the three quality guidelines).

A company which applies for certification must ensure that its products and operating processes comply with the requirements contained in the quality guidelines and the BRL. When the company has examined all its procedures and processes, the first audit can be carried out by a recognised certifying body (Kiwa N.V. at the start of the quality system). The names of certified companies are published at the website www.hortiq.nl The HortiQ certificate is valid for a period of the three years. During this period the certificate holder will undergo an annual interim check by the certifying body. After your positive reaction on our offer we can discuss in detail all the technical aspects, time scheduling and payment conditions of this project with you.

Should any question arise from our quotation, please do not hesitate to contact us immediately. This not being the situation we trust that the quotation is as requested and we look forward to your reply at your earliest convenience. Yours faithfully, Growtech Holland den Heijer B.V. Ron P. den Heijer Director

28 Water treatment / partial flow filter

For the water treatment an installation with a partial flow filter and water softener, with a capacity of 10 m³.hr., will be delivered. The partial flow filter will filter the pollution, floating parts and for instance magnetite. A part of the main flow shall be pumped through the filter, where the pollution in a polypropylene bag will be filtered. A magnet will catch the magnetism parts as magnetite. To prevent the shaping of magnetite the Ph-level of the water has to be 9,8. The partial flow filter will be mounted on the underside of the return header and can be closed with two butterfly valves. A separate pump take care of the circulation of the water. With two manometers the grade of pollution of the filter can be seen. Behind the partial flow filter a water softener is placed this water softener can soften the water of a filled installation. To fill the installation with civil water is the best choice. Because of the high hardness in the water the softening is necessary. This way you will prevent that the hardness in the water deposited on the hottest parts of the installation (the fire tube of the boiler). The softener works on basis of changing off ions whereby the “hard” ions so as calcium and magnesium will be changed with “soft” ions so as sodium. For the adding of chemicals a dose pump will be delivered. The chemicals, which are to be used for the water treatment, depends the quality of the water used for filling the heating installation. When you send us a water sample of the water, which will be used for filling the heat distribution system, then we will provide you free of charge with a report, which chemicals you need to buy locally for using the water treatment installation.

28/77

With the water softening system salt has to be used to soften the water going into the heat distribution system. The amount of salt required for softening the water depends on the quality of the water as will be used by you for filling. The salt, which should be used, is of the kind as used in dish washers. It should not give problems to obtain this kind of salt locally.

46 Fog system

Herewith we offer you a high pressure fog installation, brand Fog System. With this system you are able to increase the relative humidity and to lower the temperature in the greenhouse. 46.1 Introduction

Every 8 meter we offer one stainless steel lateral-line of 10 mm diameter with nozzles, every 2 meter. Lateral-lines will be placed in the middle of each 8 meter span with special hooks. Lengths of the hooks have to be determined on site.

46.2 Note:

A good water quality is very important for a trouble free operation of the fog system. In practice, only rain water or R.O water is usable for fog systems. When rain water is used, pre-filtration with a sand filter is necessary. Full analyse of the water is strongly recommended, to determine the right pre-filtration. Growtech Holland is not responsible for possible damage of the crop or the equipment, caused by a poor water quality, used in the fog system. BASIC ASSUMPTIONS
