I have an N. ventricosa 'red' that I'm getting ready to take some cuttings off of. I know this isn't exactly a rare plant, but I'm hoping to trade for some lowlanders for my new terrarium or anything that will grow in windowsill conditions. I prefer neps, but may also take interesting sars that aren't on my grow list.
I'm also open to cephs and helis.
I'm happy to even out the trade (2 for 1, covering shipping, throwing in my D. aliciae that has never done well for me, etc.)
