There are four functions that substrate must serve in order to support good plant growth
It must serve as a reservoir for plant nutrients
It must hold water in a way that makes it available to the plant
It must provide plants with gases and water at the same time
It must support the plant3

Types of Water culture / Hydro-culture
a. Nutrient film technique (NFT)
b. Static aerated technique (SAT)
c. Ebb and flow technique (EFT)
d. Deep flow technique (DFT)
e. Aerated flow technique (AFT)

Classification of Soil less substrates
Organic substrates Inorganic substrates
a. Peat moss
b. Wood residues
c. Saw dust
d. Bark
e. Rice hulls
f. Coconut peat
a. Perlite
b. Sand
c. Vermiculite
d. Calcined clay
e. Pumice
f. Rock wool

Peat moss
Accumulation of plant materials in poorly drained areas
As peat is a non- renewable resource, increase in price is a limiting factor
Then what is the alternative ?
Unused agricultural by-products that could be used quite easily as substrates As far as the Kyoto agreements are concerned, peat alternatives could help,since by both obtaining and using peat a lot of carbon-dioxide (CO2) is released (Block et al.,2006)
8
Coconut peat
Used throughout the world for wide range of soilless crop production
Crops like carnation, Rose, Gerbera, Gypsophila, Lisiathus, Chrysanthemum are best grown with no harmful environmental effect
High water holding capacity
Provides a buffer in high temperatures
Stimulate root growth

perlite
Pumice
vermiculite
Rice hulls

Soilless culture has many advantages over standard agricultural practices
1.Weed and soil diseases are not a problem in soil-less culture
2. High quality yield
3. Cultivating crops in any region even in regions where poor soil conditions prevail
4. Controlling the root environments and prevention of compaction
Study aims in evaluating the performance of the conifer wood biochar as growing substrate, with progressive substitution of the peat for ornamental plants.

Along with compost and sand ,Silt and garden soil showed good result
Plants parameters of growth and flowering such as
But overall leaf compost + sand
showed best results
while, farmyard manure with higher pH produced the least results regarding
all plant parameters.

Possibility of using alternative and eco-compatible substrates, shredded felt, the industrial residue of the production of chair felt pads, were chosen for substituting the coconut fibre
To verify the suitability of this new material and to identify the better combination of plant and substrate
