I've got three bulb type plants and one rooted plant in my tank and they are all doing great with no substrate at all. It's been three weeks now and it still may be stored energy from the bulbs. But I am starting to wonder if the gravel does anything beside anchor the plants. Maybe some roots are sensitive to light though these four don't show any signs of problems.
I don't understand, they should be at least slowing down their growth by now.

Hi Ralph,

A lot of the bulb grown aponogetons that grow fast. like ulvaceous, longipumulosis, and crispus are heavey stem adn leaf feeders. They also root feed. Most gravel does not have much nutrient, unless it is something like flourite, which basically just provides the iron. If you are using a liquid fertilizer, that would explain why they are still growing.
