Franky I always prefer local plant for two reasons.
1. It is tropical plant and it could survive through the horrible temperature during summer (could reach to 40oC outdoor)
2. Easy to find and buy and it is cheap
Having introduced in my last post, Thanh Hoa plant (we call it Cói Thanh Hoá) is from Thanh Hoa province, Vietnam's North Central Coast region. Thanh Hoa's terrain I would say it has all Vietnam's geology and terrain characters including river, sea, jungle, mountain, hill and delta. Interesting, isn't it? I believe Thanh Hoa Plant was discovered and used for hobby by Vietnamese hobbyists starting 80s of the 1900s. This plant can grow both underwater and land. It requires mid or strong lights, high humidity. This plant is also slow growing. It will develop into thick bush and from there you can split into smaller parts and plant them. I planted it in three areas to observe its growth: strong, medium light and shady. Ideal temperature for it is from 23 to 28oC
Medium light. Its leaves shorter than the one in strong light and it grows slower.
Strong light. In the middle of picture. It has long leaves and they spread out in order to receive as much light as possible.
Far back, next to Otto and under Cherry Barb, is The rare "Bat Cave" crypt. I planted it directly into substrate to see how it will grow.
Shady. Its leaves are long. I think it will be thinner and longer
Back to the Bat Cave crypt story. I bought it month ago from local store at Thuy Khue village, West Lake, Hanoi. I got three bushes. Since this is crypt so it is not necessary to plant it into substrate. One more reason is I don't want it grow too fast. Because most plants I have for T1 are slow growing plants
Here is how the first growing after 1 month
The second and smaller one is right behind the first bush, in shady area. I did not take picture of it because it is being covered by other plants. I will take it out someday and picture it. But not today
And the third one is here. You can see its roots developing through driftwood
As mention above yesterday I planted one small branch from first bush into substrate, in strong light and water flow.
I planted another branch directly into substrate in shady area. I also did not take picture of it as it is too early now
That's pretty much of it.
