A thermal gradient just means there's a variation in the air temp in the tank. The warmest spot should be the basking area (around 88-90F), with the temp becoming a bit cooler the further away from it that your turtle goes. My concern with the hood was that a hood that completely covered the tank would become a heat trap. If I'm correctly understanding what you wrote, though, one end/a portion of the tank would not be covered? If so, there shouldn't be a problem. (Didn't realize you were protecting your turtle from cats.
