The rings will sometimes feel loose after canning but that doesn't affect the seal. I know it's hard not to fiddle with the jars, but it's important to just leave them alone for 24 hours. Don't re-tighten any rings even if they do feel loose. Ironically, that can break a good seal. It can definitely take a while for lids to "pop." Sometimes it happens right out of the canner but it's equally likely to happen over time depending upon the size of the jar, the headspace and the method of canning (raw or hot pack, for instance).

I know what it is like to be a new canner, because I am one. In my humble opinion, the only stupid question is the one left unasked. The goal here is to make a product that you can safely to put on yours or your families/friends table with confidence. Again, ccaggiano IMHO it is not stupid to ask any question that you are unsure of and I for one and truely grateful that there are people here who are willing to help us do it safely. There is so much to learn and there is no better place to learn than from those who have been there, done that. We are not born knowing this stuff, that doesn't make a question stupid. Good luck with your canning!

Just thought I'd add my 2 cents worth of info, since this is a very interesting topic,...mainly due to my love of mango's,..have been growing the trees for 21 years now,..started in the Upper keys ( Islamorada ), and wound up here in Englewood planting various types since 2004. Wherever I live I have had a minimum of 2 mango trees in my backyard. Have tried at least 10 different varieties, won't go into the ones I didn't care for, just the 3 that I've fallen in love with and rate them at the top. No 1 is Kent, a large red mango that ripens in late July where i am now ( zone 10a in SW Fla ) The taste is fantastic IMHO ! My tree now is only in the ground one year, still has 7 red beauties still hanging on,..none have fallen into the grass yet ! Eventually this will be a huge tree, topping out anywhere from 45' to 55 ',..so the experts tell me. The fruit flies, which have attacked this tree mostly, have not shown up this year, but i still hung 2 apple-cider-vinegar jugs just to be safe,..trapped less than 20 it looks like. No 2 and No 3 are tied for second,..both fantastic producers, my Glenn is now in the ground for 10 yrs and is about 22- 24 FT tall and won't go much higher,..maybe 27 ' max. The last yellow/red fruit dropped 2 days ago, and I beat the critters to it because I was out there at 06:15 AM. i think the critters here are a bit lazy this yr for some reason ! :o) It only had about 150 fruits this yr, - that's because I gave it a heavy pruning last Sept. The year before, that tree had easily 250 + mango's. My last favorite tree, tied for # 2, is the Valencia Pride. easily the fastest growing tree of any I have planted. And it'll be the largest tree of all,..topping out around 60 ',..so I've been told ! The fruits are humongous,..and delicious,..again IMHO ! It ripens the latest, usually late Aug /early Sept. Had to cut mine down this year, but don't want to put a sad tone to this post. Getting older, not younger,...2 huge fruit trees will keep me on my toes for 6 months,..all the exercise I want now ! My friends and neighbors here call me " Mango Man " !The fruits I didn't give away are in my free standing freezer which is full to the top with frozen mango slices that will last me ( I only put 'em on my cereal in AM ) thru January !

I didn't pay attention to the whole video but it talks about grafting exotic scions to balsam fir root stock. You might find this interesting: https://www.youtube.com/watch?v=rVb66XCT7uQ
