Hi. I'm new to the forum. I bought a 1 year old leopard tortoise. I was using a coil UV bulb until I found out about coil bulbs causing eye problems. I ordered a Zoomed Powersun 100w UV bulb and waiting for its arrival in 5-6 days. In the mean time, I've been placing him outdoors for about 2 hours a day. I was wondering if that's too long or too little time under the sun. What's a good amount of time for him to be out in the sun? If it helps, I live in Hawaii.
