Ibera Greek tortoises in tropical climates.

[Shelled Nomad]

Hi everyone!

I'm planning on getting a Ibera Greek tortoise hatchling soon, but suddenly I'm having doubts if I can provide a good life for it. I prepared the following:

• I started a small garden to provide for its food. Gardening is surprisingly fun lol.
• I prepared a 65L container, with a 6-inch deep substrate mix of 35:15:50 potting mix, sand, and top soil.
• 13W 10.0 UVB and a 50W basking light shining down on one side of the container.
• Thermo/Hygrometer.
• Cuttlebone, terracotta pots and saucers, flat stones, and maybe some fake plants for cover.

However, I worry that the climate here might be too much. I'm from the Philippines, and the daytime temperatures at my area range from 80F to 90F, and humidity levels at 66% to 83%.
Do I still need to create a closed chamber, with humidity levels being consistently high? Will the tort be able to adapt? Am I stressing too much? Sorry, but I really want to be fair to the tortoise.

Thank you
