I have a small N. Ampullaria green up for trade will post pics if needed. Its only 2-3 inches in diameter. Im not able to give it warm enough night time temps for it to thrive hence the smaller size. Ive had it for over 6 months and for a while it was growing well then just slowed down once i moved all my plants to a cool basement.
Im looking for HL nep. not on my grow list.
Also interested in......well open for anything not on my grow list.
