Mungkin kalo nyiram malam-malam bisa mengundang cendawan.

mungkin biar bisa di serap matahari sore? menurut saya sih ga masalah asal siramnya rutin dan sesuai keadaan cuaca.

gak salah? katanya kalo sebelum jam 16.00 air yg tersisa di daun lalu terjemur malah bikin daun gosong?
saya kalo nyiram malam... abis pulang kantor... ;D (setelah pukul 16.00) dan kadang2 pagi sebelum ngantor.. (sebelum jam 16.00).. ;D toh nepenya gak ada yg meriang satupun...
gak ada patokan yg pasti.. hehehehe.. pokoknya selama medianya terlihat rada kering.. guyur langsung...

kalo dari yang pernah baca sih karena saat itulah Stomata sedang dalam keadaan maksimal, dimana penyerapan air yang disiram langsung di olah oleh tanaman. Kalo penyiraman malam biasanya dimana tanaman itu sedang dalam masa istirahat, itu juga menjadi alasan waktu stek bagusnya di malam hari karena mengurangi tingkat stress.
Ini detailnya tentang stomata:
In botany, a stoma (also stomate; plural stomata) is a tiny opening or pore, found mostly on the under-surface (epidermis) of a plant leaf, and used for gas exchange. The pore is formed by a pair of specialized parenchyma cells known as guard cells which are responsible for regulating the size of the opening. Air containing carbon dioxide enters the plant through these openings where it gets used in photosynthesis and respiration. Oxygen produced by photosynthesis in the chlorenchyma cells (parenchyma cells with chloroplasts) of the leaf interior exits through these same openings. Also, water vapor is released into the atmosphere through these pores in a process called transpiration.
Dicotyledons usually have more stomata on the lower epidermis than the upper epidermis. As these leaves are held horizontally, upper epidermis is directly illuminated. Locating fewer stomata on the upper epidermis can then prevent excess water loss.
Monocotyledons are different. Because their leaves are held vertically, they will have the same number of stomata on the two epidermes.
If the plant has floating leaves, there will be no stomata on the lower epidermis and they absorb gases directly from water through the cuticle. If it is a submerged leaf, no stomata will be present on either side.
Stoma in Greek (στόμα) means "mouth".
NOTE:
sebelum jam 16.00, menurut saya bukan jam 12,13,14.. tapi sudah mau ke jam 16 alias jam 16 kurang - gitulah kira2 maksudnya. Dimana sinar matahari juga sudah tidak menyengat dan adem.

Thanks untuk response-nya, tapi ternyata saya salah meng-quote infokit, yang dimaksud ternyata untuk nepenthes yang ditanam indoor dekat jendela. Klarifikasi aja.
Salam,
