| For almost a year now I have been trying to grow plant without success yet. I have a big last chamber, 4 x 1.2 x 0.8 m, where water falls about 25 cm to the pond. In that chamber I have tried all sort of local plants. Even water hyacinth did not survived - after initially seemed to grow and increase in numbers, then slowly turned yellow before finally dried up. Not enough nutrients maybe? |
