Today starts week 5 and it has started flowering. This plant is a beautiful beast: grows so fast, almost 2 inches per night. Stalk is so thick and the leaves look plastic. I'm using colloidal silver at the bottom to get pollen and fertilize the mid section and leave buds for the top. It is being grown by winter sunlight with additional 6 hours from an aquarium lamp for planted tanks that's 50w and it seems to like it.
