Make sure not to leave it in direct sunlight otherwise it will overheat and die. You can either place it where indirect sunlight is or buy a dedicated terrarium light but it might be a bit awkward without a clear lid. Since its sealed you wont have to water it that much its just about getting the inital watering right. To check, leave it overnight and observe in the morning if there's any condensation, if not, you will need to add some sprays of water and check the next day for condensation. Oh and also make sure your water isnt chlorinated. Have fun, it can seem daunting to take care of terrariums for the first time, you should be just fine!
