Dendrobium orchid suggestions needed. plz help.

[dipunn420]

Hi,

I planted four dendrobium orchid plants and hanged them in the southern facing window of my house. The plants are getting sunlight from around 3.15 pm to 5 pm in the afternoon. Rest of the time, there is sufficient brightness but that is not sunlight. Will my orchids bloom with these conditions??

Please note I am from Odisha, India and when i did buy the orchids they already got their first bloom because I noticed the dry spikes inside them. We generally experience a very hot climate, we are approaching summer, in which day time temp averages from 35c-40c and in night time it is 25-30c during the summer. So I need to re-bloom them. Please help. Any extra suggestions to re-bloom them will be really helpful.
