Conditioning in Corney Kegs

I'm getting into conditioning into Corney Kegs. I have the fittings and air to force carbonate "which I haven't tried yet" but wanted to use the keg as a big bottle and just condition normally. Mainly because I can't get the beer to lager temperature to force carbonate because I have no room in a fridge or other means to cool the beer. Can you condition in a Corney like you would in a bottle?

For a 5 gallon batch what level of priming sugar would I need?

Do I need to worry about too much pressure?

Thanks ahead of time.

When I did it, I used half the amount of priming sugar. It worked but I disliked the additional "crap" at the bottom of the keg. Cheers!!!

I use 50% less priming sugar and it works fine. Make sure to purge the keg (although I suspect this isn't all that important when naturally carbing) and hit it with high pressure to seal the lid. Then it's just a matter of waiting until it's ready to drink.
