my plant grew up to this far. its a pity i could not find the pictures i took the very first time to show some changes. the water colour has changed to green with algae at the bottom as shown on the first picture of the plant, the second picture shows the plant my the horizontal view of the plant. luckily the roots remain the same. but maybe if i used an open bottle than this one some roots would have fallen away. this plant is 20inch tall. i took the last picture last week and the picture on the bottom yesterday, i think it has reached the final height because the are no changes in the plant.
