The standard basic size of 160 ft² (16 ft. X10 ft.) with different models makes them the choice facility for the researchers to design it for roof tops or a small area available to them for conducting research year around with the desired environmental conditions. Research Greenhouse is the best way for researchers and students to explore the capacity of environment.

Details of Sabic Thermo Clear Sheet
2TS 1300 81 3 is an impact resistant, energy saving, multiwall polycarbonate sheet. It features a propriety surface treatment which provide almost total resistant against degradation caused by UV radiation in sunlight. The entire Lexan Thermo clear sheet range carries a Ten year limited warranty against discolorations, loss of light transmission, and/or loss of strength due to weathering.
Impact Strength: Sheet has outstanding impact performance over wide temperature range - 40°C + 120°C and also after prolonged outdoor exposure.
Hail simulation: As a roof and side glazing material polycarbonate sheet is subjected to the extremes of weathers storms, hail stones, wind, and snow fall and ice formation. Under these conditions the product is virtually unbreakable and is able to accommodate the subsequent temperature changes to conditions without breaking or buckling.
Light Transmission: The sunlight which reaches the surface of the earth has wavelength range between 295-2140 nm. This optical window is divided into the following section.
- UVB Middle ultra violet region 280-315 nm
- UVA near ultra violet region 215-380 nm
- Visible light region 380-780 nm 82%
- Near Infra red region 780-1400 nm 82-20%
- Middle Infra vix region 1400-3000 nm 62-0%
Polycarbonate sheet is treated with exclusively antifungal treatment to enhance the life of sheet.
Note: Saveer is the associates of GE plastics (Sabic) company for installation of polycarbonate multiwall sheet.
Ante Room: This forms a very essential feature of research greenhouse as it is necessary for temperature regulation and insect pest monitoring and its management.
Shading System (external): Different shades are available for 75% shading net (agro shade net). The specially designed rolling system –manual is there for rolling up and down the side ventilators.
Doors of the greenhouse are made of polycarbonate sheets framed in top & bottom tracks. The doors are fixed by jambs, flashings & installation hardware.
Lighting System: Supplemental lights are commonly added to research greenhouses to aid plant growth and for task lighting. We use Photo synthetically Active Radiation Lamp with Photo simulators, Metal Halide (MH) high intensity discharge lamps to meet the requirements. Our fluorescent lighting comes with special ballast specifically designed to last longer for such facilities. Read More..
A) (PAcRaTM). PAcRa W 1.7 to 2.6/60 PAcRaTM are specific action spectra lamp systems for photosynthesis for commercial production or research.
The lamps are DIN Germany, & IEC International. PAcRaTM lamp systems are marketed in India only by Saveer Biotech Ltd.
B) Fluorescent Tube light standard 4’ with complete fitting & fixing in pre ante room.
C) LED Horticultural Lights – Philips Netherlands. Marketed in India by Saveer Biotech Limited
Cooling System: Greenhouse is provided with half evaporative cooling system and Half AC, optionally it can be fully equipped with evaporative cooling system or by AC only.
A) Air conditioner units:
The system is required in high precision research where constant controlled temperature is to be maintained. User can maintain any temperature in any season. With specialized technology these systems are frost free. Read More..
(a) Air conditioner Make: SAVEER, Frost free air conditioning system with sequential timer, which is responsible to maintain following temperature ranges throughout the year-
Day Time Night Time
25°C to 300C Same (25°C to 30°C)
(b) Sequential Timer to operate two/multi Air Conditioners alternately,
Code – 013244 00473:
If a single air conditioner is used to bring down room temperature to say 25°C it gets heated up and exhausted after long hours of working. So the sequential timer is used to operate two air conditioners up to 1.5 tons each alternately; directly from timer’s powered output, operating one while giving rest to the other.
Timer’s powered output operates two air conditioners up to 2 ton each (will arrange one more phase for 2 ton A/C), alternately. Minimum ON/OFF cycle 30 min.
Input: 110/220 VAC, Phase-single.
Ambient: 5° to 45°C,
RH up to 85% normally.
B) Evaporative Cooling System
For cooling of greenhouse energy depletion system with water and pad is used. It lowers the greenhouse temperature by 8°C ±2°C Read More..
