Hmmm, I have fermented in the 5 gal glass jugs, with those, you just want to make sure to keep them out of light as much as possible.
But I think the reason I had such success in the beginning is because a gentleman just opened up a store on the outskirts of my neighborhood at the time...and I just remember I had taken a day off, decided to run into the store and mid day on a weekday, his place was dead, so his wife and him must've spent a good 2 or 3 hours just shooting the breeze and explaining to me how to brew.
And I have this MAJOR problem anytime I start a new hobby (see my tobaccos to share list)...I go friggin crazy with supplies, though my best pick up was the 5 gal pot w/the outdoor propane burner...so I was in his store a lot and we actually became good friends and he would invite me to his place for brew sessions.
Unfortunately I ended up moving a year or so later, granted I'm only about 90 mins from the old place...it's not the niecest of drives to take, so I avoid it. The area I am in now, albeit there are quite a few home brewers, no good stores are in the area.
As much as I'm not a beer drinker, sometimes when I did have a few people over for a brew session, there was nothing better on a chilly night, get the fire pit going, start the brewing, cook on the grill and let's not forget, a pipe full of baccy!
But if I were you, I'd definitely throw out the instructions, see if you don't have a local home brew store and ask them for help...so far, the whole 3 different stores I was in over time, they've all been very helpful.
