A) Low grade wood infested with mold.
B) Side by side, the upper plank molds free the lower plank with mold. Both under the same high Rh condition.
Many didn't notice it they thought the higher the Humidity the better it is. If the humidity is too high and the planks in farms are of those low graded Meranti the result will be like in the pictures.
.
.
Recommended Rh in farm is range from 70-85%. Its also depends on what type of Meranti wood (grade) you are using. If you are using the commonly low grade one which is Rm 1800-2400 per ton then anything above Rh 75% the risk of having mold on plank is very high.
.
.High grade Meranti resist mold. Even at Rh 80% and above they seldom have mold problem. If your farm is using the low grade one make sure your Rh is below 75%. Then again at this range it would not favor Swiftlets to stay.
.
Look at picture B, two different grade of Meranti were used. The top one has got no mold while the below one is infested with mold.
.
The commonly problem that Swiftlets don't build nest on farm is because the planks are wet and infested with mold. Swiftlet saliva unable to stick well on molded planks. After trying many times swiftlets will eventually look for farms that have dry and good nesting planks.
.
No points of having a good micro but the planks prevent Swiftlets from making nests.
.
Swiftlets farming is a long term investment. How would you feel after 2-3 years when you see many birds flying and out your farm but none of them stay and make nest.
.
Plank is part of micro. Don't take them lightly.
.
Good luck.

A) 低级板條有真菌。
B) 肩並肩，上部板條没有真菌, 低的板條有真菌的。 兩個在同一個濕氣的情况下。 許多不知認為越高濕氣越好。 如果濕氣太高和板條在燕屋農場是那些低级的Meranti 结果就好像在圖片的。 建议使用在燕屋農場的濕氣是從70-85%的範圍。 它也依靠您 使用什麼樣的Meranti板條(等级)。 如果您使用是每噸Rm1800-2400, 然後任何在 75%之上的濕氣风险在板條上有的真菌是非常高。 高级是Meranti抵抗真菌。 在濕氣 80%以上他們很少有真菌問題。 如果您的燕屋農場使用低级确定您的濕氣在75% 以下。 然而在這個範圍燕子是不會停留。 看圖片B，使用不同等级的Meranti。 下面的板條有真菌問題时，上面的板條是沒有真菌問題。那些燕子是不會在燕屋農場造窝，因為板條是濕和有真菌問題。燕子的唾液無法在被鑄造的板條上黏附。 在嘗試 許多时期以后, 燕子最終將尋找有乾燥和好板條的燕屋農場。 就算有最好的屋内环境， 而板條是防止燕子做窝。燕屋農場是長期投资。 您的感觉會怎麼, 在2-3年以后，當您看見許多燕子飛出您的燕屋農場，但是他們都不逗留和不做窝。板條是屋内 环境的一部分。不可以小看他們。祝您好运!
