It depend on how many competitors nearby for the birds to test out each farm to decide to stay permanantly. Roving size just nice. How big is the interentrace from roving to nesting? Middle or left right double interentrace to nesting? Personally never test Nest Tech CD I know they have many different one for sales. When you purchase did they ask you where are you going to use the CD? They claim they won't sell the same CD to the same place. How's the sound quality to human ear? How fast the external sound lure birds to come explore after switch on?
29-32 degree seems unusually high for a concrete farm.  Mine wooden farm do min 26 max 31. Try to get readings up from nesting plank/ceiling area as that part is more important. Observe which part of your building get the most direct sunlight and  get temperature reading at that wall/ceiling.

You haven't bought amps? Don't worry that cheap amp I open up already got big cooling fin inside. Though the price cheap inside the material not chapalang at all. Not high tech but at least the capacitors are Japanese made Rubycon brand. I use that amp for internal sound 24/7 on. It operate at much lower temperature than the 5.1 amp(old amp) I use for external sound. Personally I prefer amp without fan. Why? If a model is design with fan mean it generate quite high heat must have active cooling method. If the fan used is normal sleeve bearing fan when running 24/7 after some time oil inside the bearing will dry off then become spin slower or worse become jammed.  Those without fan already design to work with passive cooling method which won't fail. 

Is there any farm in kedah?

How much you bought it for?

Seeseng ,

What is the watt of your Amp?

15'x30' is a maybe a short signted people or budget limited design. Swiftlet farming is a very long term investment. First 5 years most of the successful farms can't earn back the capital yet. My store room farm also bigger than its 1 storey lah hehe.  Is the 130K including planks installed? Here got a friend's standalone 30x100. 5 and half storeys. Full cost 250k still got small change.  In my opinion the 15x30 will do ok due to the good area with good chirp. But it's a waste of land.

20x45 still very short sighted.Buying a land averagely it needs 8mth to yrs++++ to get the name transferded. jabatan tanah takes time. In any even if there  is a problem the land title can't be transfer be ready yr farm to be demolish. Unless that is yr father's land then ok. Buying land have to be careful.Some land take more than 2 yrs to settle. Unless you wait till all transfers are done then only build yr farm. That would be few years from now.

Too ulu , be ready yr farm break in all yr nests CURI.(security problems) The birds will never return any more.
Too ulu elctricity and water are problems. .

Commercial lot will be quicker to set up a farm and running. But may face competition from nearby farms. First batch of bird stay may take some time. I've heard stories about standalone farms with no competition in few KM radious get first batch bird stay on the first day of operation. From my own observation more swiftlets go for food at padi fields. Maybe due to convenient fly path on top of short plants. The same area where most flying insects fly. For oil palm plantation only part of the insects will fly on top of the trees. Some fly between the trees where it's risky for swiftlets to fly lower than tree top.  So the numbers available to eat should be lesser than padi fields. 
IMO the flying insects like swampy wet land since I've seen groups of birds cari makan over a wild keladi field also.

Contact Crystalswiftlet of Penang or Nestech of Johor. Simple pay them they will handle everything for you from A-Z. All you need to do is sit back and wait for the time to harvest.

HA HA..Ha....HA..ha...Good advise! Now u know wat I mean? I am sure u know more now compare to just a week ago Right! So take it easy. The biggest problem with those who want to start is that they tho they know everthing. That is y 90% of the farms failed miserablely.

Some tho after going to seminars and picking up few books they have found the golden treasure or the have broken the Davinci code. LAter to discover that what they had acquired and learned  is just a nursery rhyme amongst books.

Take it easy!

IMHO, a biased report supported by a consultant selling expensive swiftlet product catalogue. How do they get those figures? Simply speculation lah. Same like Bolehland how high the % of economy growth and how low the inflation rate reported lor. Be proud! Better than Myanmmar what?  U know I know lah.
Equipments: Those well known companies selling at high price sure accurate? Example 1 well known company often publish articles in newspapers selling one model of double fan humidifier with build-in hygrostat at RM2988. Turn up the hygrostat has 15%+- accuracy. The hygrostat I'm using is made in China with 3% +- proven to be same results as my Taiwan made hygrometer/Thermometer.
Dehumidifier is often use in countries with 4 seasons where in the spring indoor humidity so high the floor become wet with water drops all day long. Also widely use in rooms with electronic devices which need a dry environment. It's kind of like air purifier thing. 1 part suck in air to cool down with refrigerated fins. The humid in the air cool down become water and collect inside the equipment. Then the other part blow out dry warm air.  Often dehumidifier come in humidifier/dehumidifier with build in hygrostat 3 in 1. Has a high/low setting.  When humidity high it run as dehumidifier. When humidity too low it can be set as humidifier.  But these type of equipment not practical in farming.  Can imagine how many units needed to cover whole farm?

CD sound quality better than normal MP3. But if when we extract the CD track into MP3 use high bitrate of 320kbps and sample rate of 48khz the output quality is comparable to CD quality. For farming we output to tweeters. MP3 and CDs sound LPPL only. MP3 has many advantages. A normal CD of 63 minutes if converted to MP3 put inside a CD can fill in 10 hours of continue playing non-stop.  If put inside USB drives or memory cards to play with supported players. Players can last longer lifespan because of no moving mechanism and lower operating temperature also no laser lense aging problem cause poor quality playback or choosy with discs.

Humidifier can reduce some temp but not much. It reduce heat through condensation. But humid in the air also trap heat. From what I tested at my farm by increasing humidity from 65%RH to 85%RH temp only drop 1-2 degrees. So not practical to rely on humidifier to reduce temp. Humidity mainly for the purpose nests won't too dry become crisp no need to be too exact. 80%-90% seminar teach one ka?
Determine where the heat come from and prevent heat from come in.  Not heat come in already then buy water-cooling fan system to cool it down.  Actually there are actual farm using air-cond. Owner want to save $ because install insulation at roof and wall more expensive. Air cond temp set to 26 so not cold. A thermostat control the power to on at 29 and off at 27. So it only on at hottest moment of the day. Result: Before install air cond no bird stay. After got air cond bird stay.

Yes, we have to be careful about rats as well as roaches. Anyway there is powder to rid them.

I just attended the Genting Swiftlet Conference (Wholeseller, I think) and it's boring. There suppose to be a question and answer session in the afternoon and it was missing maybe because after lunch, everyone gone to casino. Me and my friends were waiting there like stupid.

Huge attendance but poor presentation and nothing new............I should have gone to the casino but then, Rm600 paid....must try to get money worth.

Anyone there? What your opinion?
