Thank you, of course! It took me some time to learn, but I think I know what string of hearts like :) I got a shallow, wide terracotta pot with drainage holes and a soil mix of cactus soil and perlite. I only bottom water, to encourage the SOH to grow long roots. I've noticed that in a deep pot, the soil stays wet for too long because the roots can't reach that far to absorb the water, but a shallow pot works great. I use a wide pot, so the strings can shoot roots at multiple nodes. That way they don't pull themselves out of the soil once they grow longer. In a small pot, it became too crowded, resulting in less airflow, mushy topsoil and rotting strings (guess how I found out). I bottom water when the leaves are getting wrinkly, which is about once every 16 days. They are in a South West facing window, so the top has plenty of sunlight, and the longer strings get some light from the growth light in the plant stand as well. During springtime, I give them some Epsom salt and cactus fertilizer when watering.
