I have lost a couple in the past, this one i recieved as small seedlings togheter with his sister both mounted in the same piece of cork, this one very vigourous i have grown for a bit less than two years and already bloomed with two flowers while the sister is somewhath of a runt as is still half the size of this one, so I think genetic also play a role, all this said i grow it mounted on cork with high humidity, high ventilation, intermediate temp, phal light and same fertilizer routine as everything a g of 30 9*6 in 10lt waters or a couple grams of 15 5 15 cal mag in 10 lt
