For Hatchlings I would recommend a "close chamber" type enclosure such as an aquarium and storage tote. Enclosures such as these do a better job at maintaining proper temperature and humidity levels as opposed to open tortoise tables where that can be next to impossible.
Temperatures will fluctuate through the enclosure. I HIGHLY recommend purchasing a temperature gun so you can spot check temperatures throughout your enclosure. Below is a list of what temps in your enclosure should be around.
Basking Spot: 95-100 degrees
Warm Side of Enclosure: 85-95 degrees
Cool Side of Enclosure: 80-85 degrees
Hide: 90 degrees
Tortoises still need heat at night but should be in total darkness. Use a CHE (Ceramic Heat Emitter) for heat without light.
Humidity is key to raising a healthy, smooth tortoise. The higher you can get the humidity the better. Try and shoot for 60-80%.
Soaking your tortoise is extremely important. This should be done as often as possible, daily for 20 minutes in warm water is ideal.
Tortoises are reptiles so they absorb moisture through their skin to hydrate. Soakings allow them to get the hydration they desperately need.
This is the part that confuses most people, don't over think it. Tortoises need UVB to simulate sun light. I strongly recommend "tube" style florescent UVB lights or a Mercury Vapor UVB Basking Bulb. Avoid coil bulbs as they have been known to be harmful to tortoises eyes. If your tortoise lives outdoors no UVB is necessary.
Sulcatas are grazing tortoises so grasses and weeds should be the bulk of your tortoises diet. Spring Mix Lettuce (without spinach), Mazuri tortoise diet, hay, Mulberry, and Hibiscus leaves are excellent options as well. Be sure to sprinkle calcium powder with Vitamin D3 on their food twice weekly.
Recommended Material List:
There is more than one way to properly care for a tortoise. These are just some basic materials I recommend. Materials will vary depending on what type of set-up you choose to go with.
-Basking Bulb (Wattage will depend on your enclosure type and size)
-UVB Bulb (Tube style or a UVB/Basking combo bulb recommended, not the coil type bulbs)
-CHE (Ceramic Heat Emitter)
-Shallow food and water dish
-Substrate (Coconut Coir and/or Cypress Mulch)
-Log Hide or other humid hide
-Thermometer and Hygrometer (Temp Guns are HIGHLY recommended)
