Depends on the situation really, in a tent that's a lot of playing to get the environment right since they're not perfectly sealed and have their own challenges. Growing in a sealed room where you have a more stable environment given you've done your research and have the right equipment would probably be much easier to maintain a larger grow.
That being said they don't call it weed for nothing, it's a fairly hearty plant even though most of us act like they're not. My first harvest looked like it was about to die on at least 3 occasions and came out alright still. You're definitely going to have your issues no matter how big the space as a new grower, just make sure you can access all of your plants easily and you should be fine.
