Dendrobium flask temperature

[dendroboii]

Hi,
I have a question regarding flask care. So last week I did my first flasking. I sowed seeds from some Dendrobium pods, which the parental plants grow well in my small outdoor garden. My place is very hot and humid all year long (temperature reaches >33 oC in the afternoon and 27-ish at night). It's been around a week and no sign of contamination has appeared.

My problem is I have very limited space to store the flasks inside, so I keep them on the balcony, with 11-12h indirect sunlight. The temperature, as described, can reach 35 oC. So I'm just wondering if this range of temperature will affect germination and growth.

I've read that the ideal growth is achieved at room temperature (25 oC), but some people also say the temperature which the parental plants grow at. I need tips from someone with Dendrobium flasking experience. I have some more pods ready to sow, so just making sure I'm doing the right steps. Thanks!
