Thanks for responding!
The bulbs have grown more than it already was bringing the plant when they buy it. They're all the same size.
Anyway I put moss around the roots, I hope that this will increase the availability of water and the following bulbs grow larger.
The daily watering in the greenhouse and never falls 70% humidity and 20 ° C more than ever, now with the heat of summer may reach 25 ° C.
I have really wanted to flourish
Within days the orchid bloom "BC. Binosa". Content myself with this flowering.
Thank you very much!
