How do I flower these Utrics?

[cindy]

Anyone with tips to flower these Utrics? I need help because Singapore has a 12-hour photoperiod year round. Please let me know if I need to cut down or up the hours. I can't change the climate but I can shade the plants or put them under FL. ;D

U. bisquamata
U. dichotoma
U. livida
U. longifolia
U. parthenopipes
U. praelonga
U. sandersonii 'blue form'
U. subulata

Thanks in advance.

12 hours should do fine for most of the species on your list. There not the most demanding/ sensitive species.

Let there be (sun)light

Move the U. subulata and U. bisquamata to another room... preferably in a different country! ;D

They are both highly invasive and should you succeed in flowering them, they will rapidly contaminate your other plants.
