It's really a question of volume. If you're growing pounds, you probably need large half gallon/full gallon sized jars. My 'grow' was very small - I grew 3 plants I had to keep under 6' due to the outdoor location and of course you want to keep each variety in separate jars, so I opted for the pint sized jars. I ended up with 9 jars after losing about 20% of my buds to bud worms (rookie mistake), then 1 jar developed a 'mildew' smell so I trashed it. That left 2 jars of 1 plant and 3 jars each of the other 2 plants. When 1 of my 'smoking' jars gets low, I dump buds from a 'storage' jar that has a Boveda pack in it keeping it fresh. The 'smoking' stash is left open a few hours to reduce the RH and make the product better suited to smoking.
So jar size is relative to the size of your grow and how you like your product.
