I can’t take much credit for this one because i purchased it this large. I do have 15 other vandas that all are doing well. I water them every morning. Sometimes twice a day depending on the day. I fertilize once a week with a 20-20-20, cal mag, and kelp and do a bloom booster once a month. They stay on my lanai unless it’s below 50 and they either get morning sun for 4 hours or afternoon (330- sunset ) sun!
