Could you put a 5 gallon batch into a 5 gallon carboy as the primary fermenter if I put a overflow hose on it until initial fermentation is complete?

I brewed my first batch last night and was a little sad to put it in a plastic fermentation bucket because I wouldn't be able to watch the initial process. I plan on purchasing a 6.5 gallon carboy coon for this reason but until then and for future knowledge would it be pushing it to do this?
 
I wouldn't - there's really not enough room for 5 gallons of beer, and you're going to risk blowing the top whether you have an overflow hose or not.
 
Use the bucket. After one day of watching there is really nothing new to see.

That said, I have a bucket and a couple of 6 gallon Better Bottles. I prefer the BB's because I can see the fermentation.
 
I have always used a 5 gal carbon for 5 gal batches. I use a 1 inch diameter blow off tube always for the first 4-5 days then switch to airlock. Never had a problem at all. Not much headspace in there but it works great.
 
As long as your doing a fairly normal beer (not super high abv, etc) you should be ok.

Could always do a 4g batch as well. Just multiply all your ingredients by .8. The only thing that won't be perfect is hops but you'll be close enough
 
I just did a IPA in my 5 Gal carboy. Used a 5/8" blow off tube stuck on the 3 piece air lock. Worked just fine.... of course I am still trying to clean out that damn tube. I wanted to see the action. I plan to do it again, albit with a larger diameter blow off tube.
 
I just used my 5 gallon carboy for a 4.25 gallon batch. I used beersmith to set everything up for the smaller batch & it was a piece of cake. Blow off tube for sure, but I always use one when I begin fermentation. I did get some krausen in the tube, but it's an imperial ipa at 8.5%, so I had some good action.
 
not every beer blows out but you never really know when it will. i routinely put 5 gallons of wort into a 5 gallon fermentor without a problem but from time to time it does blow out.
