It is very easy to destroy the internal environment but it is hard to make a good one. This is what happened if you do not know how and what it takes to create a good Micro. To screw up one it is as easy as ABC.
I had visited many farms and met up with many farmers. I discovered one common thing about them is that they do not know how to create a good and stable Micro.
Be it a big farm of a small one all of them shared a common idea “more is always better”. More Vent-holes is always better, the higher the Rh the better, the more nesting planks per each sq/ft is better and so on. Some even made pyramid planking system trying to maximize on future harvest which will never come if they can’t even make a good Micro now..
In-depth understanding is very important in Swifttlets farming. It looks simples and easy. Anybody could undertake the whole construction of a new farm. Anybody could build one and own one but could everybody have a successful farm?
I have received countless phone calls and emails asking my opinion and solution to their failed farms. Some of the common questions were:
“My farm’s temp is 28c, Rh 80%, located in a good location, using the best sound, using …. Why after 2 years only have 10 nests?”
“My farm is built by ……(who and who..) .Why after 3 years still the same number of nests?”
Let’s get back to the topic of Vent-Hole, it is uncommon to see 10 Vent-Holes or more in space of 20ft. Many had asked so what is the so called standard number of V-H for 20ft then? Definitely no standardization here.
The answer is depends…. Where the farm located? What is the internal design (partitioning & wall section)? What is the material of the wall…and so on. All these added up would give us a clear picture of how many V-H is required in a particular farm. In fact I had written about the V-H in some of my articles way back in 2008 or 2009 if I could remember I did mention about the advantages and disadvantages of having too many and too few V-H.
The above picture shows the Hot air from outside would enter the farm thru the V-H and pushes out the cooler air in the farm. This makes the temp inside the farm higher.
Whereas for farms that have high internal temperature (32C-34C) then having many V-H it would help to reduce the temp slightly.
The famous theory of “combination of bottom and top V-H” which written in many books only works for environment that has no wind movement at all which is impossible. Tell me which area a farm located 24hrs there is no wind movement? Yes there is a place …in the SPACE and the Moon.
In picture B it shows hot air constantly escape thru the Top V-H. It means the ceiling or the Nesting planks areas are constantly hot with hot air. If this is the case then it would be very hard for the Swiftlets to build nests.
If you think beyond this and use a little of your intelligent you would discover that building a good farms is more than just reading books and attending seminars.
Good Farming All!
