3 plantalux.pl RECENT PROJECTS We have been using horticulture LED COB lamps manufactured by Plantalux Sp. z o.o. for hydroponic lettuce cultivation in greenhouse since December 2017.

What is more, due to replacing HPS with LED lamps our electricity bills are 3 times smaller. We recommend Plantalux Sp. z o.o. as a reliable horticulture LED lamps manufacturer.

4 4 plantalux.pl LIGHT SPECTRUM Our lamps use light sources of different spectrum so as to make sure that lighting conditions are appropriate for your cultivation. Below are three types of diodes of various wavelengths and of various total red to blue ratio. Each description displays a table presenting the spectrum divided into different wavelengths. Plantalux Strong Red - LED COB of significantly high total red to blue ratio (87:13). Very high far red percentage that equals 20% of the entire spectrum. Such composition of wavelengths is ideal for the cultivation of vegetables, fruits and blooming flowers. Range [nm] (PAR) (far red) (red) (green) (blue) (UV) Percentage 80% 20% 65% 3% 12% 0% Range [nm] (PAR) Plantalux Double Blue - LED COB of distinctly broader range of blue colour in the total spectrum. Such effect could be achieved by developing wavelength of double peak within nm. Due to that this diode we changed total red to blue ratio for the benefit of blue (75:25). Such mixture lets promote early stage of plant life especially in the vegetative phase. Appropriate mixture of wavelengths creates light suitable both for plants and human eyes the CCT of this diode is approximately 5500 K (far red) (red) (green) (blue) (UV) Percentage 85% 15% 52% 12% 22% 0% Citizen - LED COB of proven positive impact on plant growth. It was developed and manufactured by Citizen Electronics - a well-known Japanese manufacturer of COB and SMD LED. Due to good red to blue ratio (82:12) it lets you achieve better effects in greenhouse cultivation. Independent tests conducted by different research entities demonstrated its high effectiveness. Range [nm] (PAR) (far red) (red) (green) (blue) (UV) Percentage 90% 10% 62% 12% 16% 0% We can develop tailored diodes of different light spectrum for our customers.

5 AWARDS plantalux.pl 5 During this year edition of Fruit and Vegetable Industry Fair, Prof. Pieniazek s Prize was awarded for the fifth time. The jury awards products which are most innovative and beneficial for gardening, environment and society, reported by the Exhibitors and Sub-exhibitors. One of the awarded companies was Plantalux for its horticulture LED lamps and intelligent system to manage plant cultivation in greenhouses.

intensity are the main factors influencing final crop yield.

6 6 plantalux.pl CONSTANT DEVELOPMENT Content of chlorophyll A and B, carotenoids and photosynthesis intensity are the main factors influencing final crop yield. Using Plantalux s horticulture LED COB lamps allow to increase those contents and accelerate some processes. We conduct research and development to make sure that lighting we manufacture meets all your requirements.

RESEARCH AND DEVELOPMENT plantalux.pl 7 Abstract of research results conducted at University of Life Science in Lublin, Poland between October 2017 and February 2018 is presented below.

Chlorophyll A content [mg g -1 wet weight] Sunlight + LED 1,93 Sunlight + HPS 1,58 Chlorophyll B content [mg g -1 wet weight] Sunlight + LED 0,53 Sunlight + HPS 0,42 Photosynthesis intensity [μmol CO

7 RESEARCH AND DEVELOPMENT plantalux.pl 7 Abstract of research results conducted at University of Life Science in Lublin, Poland between October 2017 and February 2018 is presented below. During the study the influence of different lighting on tomato, cucumber and basil growth was examined. The research took place in a greenhouse and a darkroom (no sunlight). Chlorophyll A content [mg g -1 wet weight] Sunlight + LED 1,93 Sunlight + HPS 1,58 Chlorophyll B content [mg g -1 wet weight] Sunlight + LED 0,53 Sunlight + HPS 0,42 Photosynthesis intensity [μmol CO 2 m -2 s -1 ] Sunlight + LED 8,21 Sunlight + HPS 6,84 22,15% 26,19% 20,03% TOMATO IN GREENHOUSE Content of both chlorophylls A and B were higher of 22,15% and 26,19% respectively in plants cultivated under Plantalux s horticulture lamps LED COB than under HPS. Using LED lamps led to increased dynamics of the photosynthesis process. Its intensity in tomato leaves was higher of 20,03% compared to HPS lamps. What is more, all above parameters were achieved with energy consumption lower of 67% compared to HPS lamps. CUCUMBER IN GREENHOUSE Yield of cucumber cultivated in greenhouse under Platanlux s horticulture LED COB lamps was higher of 73,33% than that under HPS lamps. Average weight of cucumber was only slightly increased under LED lamps by 1,57%. Number of cucumbers collected from a single plant that was 62,50% higher under LED compared to HPS. All above parameters were achieved with energy consumption lower of 67% compared to HPS lamps. Cucumber yield [kg plant -1 ] Sunlight + LED 1,04 Sunlight + HPS 0,60 Average cucumber weight [g] Sunlight + LED 82,22 Sunlight + HPS 80,95 Number of cucumbers from plant [pcs.] Sunlight + LED 13 Sunlight + HPS 8 73,33% 1,57% 62,50% Wet weight [g plant -1 ] LED 19,35 HPS 15,89 Dry weight [g plant -1 ] LED 2,18 HPS 1,76 Essential oil content LED 1,05% HPS 0,75% 21,77% 23,86% 40,00% BASIL IN DARKROOM Basil cultivated under Plantalux s horticulture LED COB lamps had wet weight increased by 21,77% in comparison to those under HPS lamps. In case of dry weight that trend was kept weight was increased by 23,86%. Content of essential oils that are responsible for aroma was increased by 40% under LED compared to HPS. All above parameters were achieved with energy consumption lower of 67% compared to HPS lamps.
