  1.  Orchid climatic requirements and water requirements.
  • Temperature: – Minimum 15C & Maximum 33C.
  • Humidity: – 60 – 80 %
  • Water quality is also important,The electrical conductivity should be less than 0.5 ms/cm
  1. Orchid Shade Net
  • The shade house for the horticulture of Dendrobium have flat roofs.
  • Net with a width of 4 metres is used.
  • There are two tiers of roofs, one higher above the other, to ensure adequate ventilation.
  • The distance between the upper and the lower roof is about 20 – 30 cm.
  • The nets of the upper and the lower tier should overlap each other by about 25 – 30 cm.
  • The piles for  the  structure of  the shade house can  be made of  concrete  or steel.  The concrete piles should have a thickness of 3.5 x 3.5 inch and a height of 3.5 m. from the ground. The upper ends have a hole drilled through for fastening slings.
  • Piles along the edge of the shade house should have a thickness of 5 x 5 inch.
  • Along the edge of the net small wire is used to be tied to the steel pipes.
  • The net should be placed at the sides of the shade house at an angle of 45 degrees to serve as a protection against the sun and winds.
  • The net should be placed at the sides of the shade house at an angle of 45 degrees to serve as a protection against the sun and winds.
  • The feature of nets used as protection against the sun and winds seen from the side.

  1. Benches for Cultivation
  • For making the stages to place the orchids, concrete piles with a thickness of 1.5 x 1.5 inch are used.
  • The piles of the stages for placing the orchids rise above the ground about 60 to 70 cm.
  • The stage is 1.20 m wide and the width between two piles is 80 cm.
  • 1.20-metre-long concrete beams are placed between two piles.
  • The way of how to place concrete beams on the stages.
  • When not using concrete beams, steel pipes will do the job quite as well.
  • The laying of water pipes in the shade house saves one from dragging the hose for long distances.
  • The branching of the water pipe into various directions makes connecting the hose and watering the plants more convenient.

  1.  Planting Media
  • Coconut blocks used for planting Dendrobiums
  • Every time when doing the planting the stems should be erected completely vertically.

Little bamboo sticks that are stuck in the coconut blocks may be attached to the orchid stems to help keep them in position.

  • Plants of a height of 10 to 15 cm only just planted in coconut blocks.
  • Dendrobium that were planted about 6 – 7 months ago.

  • Insecticides or fungicides can be mixed together and should be applied by spraying once every 7 to 10 days between 4 pm and 5 pm on a fine day.
  • Fertilizer should be sprayed in the morning once every 7 to 10 days. During heavy rainfall fertilizer should not be used. It also should never be mixed with insecticides or fungicides.

Right Technology in farming yields better production

Right Technology in farming yields better production


Right investments in technology can bring higher returns in agriculture. At one end I meet farmers who don’t earn more than 40 thousands per acre per year while some of the farmers are easily making upto average 4-5 lakhs rupees per acre by adopting right technology.  One such technology is use of right colored plastic mulch.

The title image is from a tomato farm near Hasergetta in Bangalore. All other parameters like seeds,date of planting, variety of seeds, fertigation all being same the only differentiator is the colour of mulch. (even the supplier and make is same).

Plastic mulching is always used with well designed drip irrigation under the cover. You can see two kinds of mulch in the above image Black and white and black and silver

Black and white mulch must be used in summer time planting in most of the warm countries. Black and white mulch keeps the root zone soil cooler in summer. It reflects upto 60 % of photo active radiation back to the plant. This results in healthier and stronger plant hence higher yield compared to no mulch or other colour mulch.

Using this technology farmers have been able to get upto 60-90 tons of yield per acre in a growing season in India1


Black and  Silver mulch good for winter planting. Black and silver relfects the PAR and some other parts of spectrum back to the flying insects thus reducing insect atttacks.

Following is the image from a farmer Tanaji Thete from Nashik who used black and silver mulch for the first time in turmeric. He got an yield of approx 30 tons per acre from this field.




So it is important to select the right mulch colour based on the time of planting.

Doing Greenhouse farming? Extend the life of greenhouse film by 25 %

Premature damage (Not related to UV Degradation) of Greenhouse film is a major issue among greenhouse farmers in India.   This premature damage happens due to degradation at the contact point with metal as follows:

  1. Metal used in greenhouse construction is Zinc coated.
  2. Zinc tends to migrate from the metal to the plastic at the contact point.
  3. Metal also gets heated due to adsorption of IR.
  4. Warm meatal transfers heat to the plastic in contact.
  5. The greenhouse film gets warm during the day and cool during night.
  6. Alternative heating and cooling tends to make plastic brittle and weaker at contact point.
  7. The heat also increases zinc migration to plastic at contact point.
  8. The zinc migration can be easily by black marks on the plastic at the contact point.
  9. The zinc migration also degrades the plastic.


What is the Solution??

  1. Use of water based paint at the metal before installation of plastic
  2. Use of water based paint from outside of greenhouse film in a 4 inch strip at the contact points.


Water based acrylic paint from outside the greenhouse film at the contact This paint acts like an Insulator


Roller brush to apply the paint.

What is the available product??

Solar Guard is the best product available in the market. It is manufactured by a Dutch company Mardenkaro which specializes in film protective paints for horticultural application.. Solar Guard is a high quality paint  which does not contains harmful solvents or other phytotoxic components.

Why Solar Guard is different?

  • Solar Guard pigments is made up exclusively out of microscopically fine particles of titanium oxide that provide the paint high covering and heat reflecting capacities.
  • Solar guard will not harm the crop.
  • Solar guard has fully acrylic binding agent which makes the paint extremely resistant to UV Degradation. It is also a flexible paint post drying so it does not flake out due to flexing of plastic.
  • Solar guard adheres perfectly to horticultural plastic films and metal construction parts.
  • It has no organic solvents or other components that can harm plastic.
  • Solar guard is water based and it is environment friendly.


Directions of Use:

  • Remove any dust and dirt from the plastic surface.
  • Remove any rust or grease from the metal surface.
  • Stir well before application and this with water as desired.



Solar guard must be applied by roller brush as follows.


Clean the brushes and rollers with water after use.


At a small cost of about 4 Rs. Per sq. M of greenhouse surface area you can expect to get minimum 25 % extra life of the plastic on the terrace.

Why TheAgrihub?

#TheAgrihub is world’s first agriculture specific online discovery platform. This is the need of the hour for agribusiness and farmers across the globe.
Here are a few scenarios which you may relate to:

Difficult local Sourcing:

  • I have been in International Agribusiness for 22 years. Having travelled more than 30 countries for exhibitions, conferences,business and spending several dedicated years in this sector ,Idid not know where to buy basic fertilizers and pesticides for my home garden at Bangalore.
  • One of my friends staying in a posh locality in Bangalore was on the lookout for some Papaya seeds for his farm. He did not know where he could buy superior quality seeds. I rescued him by getting Red Lady Papaya Seeds from Known-You seeds using my business contacts.

Information on latest available Technologies:

During my travel I have come across several technologies where farmers can earn big money by investing in protected cultivation using greenhouse and net house farming. But for a common farmer or business owners it is impossible to know all latest technologies at one place.

Business Sourcing:

  • For traders, retailers and farmers discovering new products and technologies can be a herculean task in the scattered cyberspace or exhibitions. I had a recent experience which validates this argument.
  • In my existing agribusiness in Bangalore I wanted to source products useful for organic farming and Integrated pest management. I travelled to Shanghai for an exhibition and zeroed on sticky traps made in Korea distributing in India. Subsequently I discovered better quality sticky trapsbeing manufactured right in Bangalore just 40kms away from my office. With this small information I could source my product locally and gained both on input costs and business margins.
  • Expensive Exhibition and product showcasing and launches:
  • International businesses looking to expand their business in other countries spend thousands of dollars to showcase their existing products and launch new products in exhibitions. Duration of these exhibitions is only 3-4 days. Often you receive more casual visitors than targeted customers.
  • There were many other real life scenario both for agribusiness and farmers that I came across. This motivated me to bring out a solution to make agri inputs sourcing easy. The Agrihub has been developed to address the above mentioned problem scenarios and to make product sourcing easier.
