I have 4 compartments (see picture) in the top of our waterfall. Each are approximately 7x5 and 2 1/2 to 3 inches deep. Could I put pea gravel in these and plant something? What plant would you suggest that might be suitable? I'd like to cover the black plastic a bit more. We usually float some hyacinth in the big center portion.
Thanks for help and suggestions.
