In all the years of trying to grow this Hoya I never so much as got one peduncle to form let alone try to bud up. The standstill all changed for me this year when I moved 2 of my 8 plants from a 14 hour day length to a 12 hour day length by shifting them to another grow tent where my timer was set for the lights to be on for less time. Almost immediately peduncles began to form; I was completely shocked as I had about given up. Along with the peduncles buds began to form!
