There are 8 basic needs for the Fertigation method in a modern farming concept. We will cover part of it in this post and will continue on the next post:
1) Greenhouse - It is advisable to have a curved shape design to withstand strong winds and heavy rain especially for the greenhouse plastic film roofing. The film is secured by a special clip to the structure. The material of the structure can be Aluminium, G.I pipe or 
black pipe. If you want an 'A' shape structure, you can use arcylic or carbonated plastic for the roof. Even though it is much expensive but its durable and last long with a very minimal maintenance needed. It is always used in the West especially countries that have four seasons. The plastic film is cheaper but not long lasting. Even though the plastic can last up to 5 years but after about a year or two, you can start seeing a layer of green fungus on its surface
( especially in a tropical country like Malaysia, Thailand and Indonesia) which can minimise the sunlig
ht for the plant and thus inhibit the plant growth. To get rid of it is very tedious not an easy job. Strong wind can also unsecured the plastic greenhouse film from the greenhouse structure (as can be seen from the photo below). To fix it back can be tough and need a lot of people to get it done. You must also try to prevent the plastic film from getting contact with pesticide, fungicide or any chemicals especially solvents as they might deter the quality. So, you decide what material to use. The important thing is that the sunlight can pass thru the 
roof.
