Hi . This is our hermann indoor enclousure my boyfriend built for our tortoise. It is 225*150 cm. It is for overwintering purpose because he spends his summers in our garden. Substrate is coconut coir which I water but humidity is a problem because it is placed in bedroom with heat on. He has a 10% uvb lamp and a heat lamp.Temperature is 25C and under heat lamp 32C What should I put under the coconut to increase the humidity? Please help with ideas and say if something is off because he is a little sleepy so I'm doing what I can. Also, It was evening when the photo was taken so it looks a little dark. Should I place my clip lamps further away one from another? .
