1 g, 3 g, 5 g, 10 g: Which CBD flower size should you choose?

You’re browsing your CBD shop and might be torn between several formats. I get it! On paper, the difference seems simple, but the right format also depends on the price per gram, how often you use it, and how you store your flower after opening it.

Things to remember

• Larger sizes often offer a better price per gram.
• Once opened, a flower should be stored away from light, heat, moisture, and air.
• The best format is, above all, the one you can consume before the flower gradually loses its characteristics.

The price per gram often decreases as the package size increases

Take a look at the prices listed at a CBD store: 1 g usually costs more per gram than a 5- or 10-g bag. And no, it’s not just because the store wants to push you toward the larger size.

Packaging accounts for a portion of the product's cost. A pouch, a label, a closure, a box, order fulfillment, and certain logistics operations are required for each unit sold. Whether the pouch contains 1 g or 10 g, a portion of these costs remains relatively similar.

Let's take a very simple example:

• 1 g at 10 € = 10 €/g
• 3 g at 24 € = 8 €/g
• 5 g at 35 € = 7 €/g
• 10 g at 60 € = 6 €/g

The calculation makes the difference immediately apparent.

With a 10-gram package, you pay less per gram. But keep in mind that a lower price per gram doesn't automatically mean the larger size is a better deal for you.

If you use very little CBD flower, buying 10 g just to take advantage of the price may mean you end up keeping the product for much longer after opening it—and that isn't necessarily a good thing.

3 g: the sweet spot for moderate consumption

3 g is suitable for someone who uses the flower regularly but not every day. It’s also a good amount for keeping the same product on hand long enough to get a better idea of it.

The price-per-unit ratio generally starts to become more attractive than at 1 g.

And if you have several favorite flowers, 3 g also lets you mix things up without building up a large stockpile.

5 g: for regular use

The 5-gram size starts to make sense if you use flower several times a week. The price per gram is generally better, and the quantity is still manageable once the package is opened.

You can also divide your 5 g among several small, airtight containers instead of opening and closing the same bag over the course of several weeks. This can limit repeated exposure to air, provided you use appropriate, clean containers.

10 g: the value size… as long as you store it properly

The 10-gram size generally offers the lowest price per gram. It’s a good option if you already know which flower you like and use it often enough to finish the quantity within a reasonable amount of time.

But a large package requires more care once it’s opened. CBD flowers contain volatile aromatic compounds and cannabinoids that can change over time. Light, heat, air, and excessive humidity can accelerate certain changes.

When it comes to storage, it’s no secrethow important packaging is for flowers and resin. So be sure to use an airtight container—preferably one that’s opaque—and store it in a cool, dry place away from direct light.

Above all, avoid leaving the bag open on a shelf for several weeks. The container must be resealed properly after each use.

How should you choose your format based on how often you use it?

I have a very simple rule: go by your own pace rather than the listed price.

You use it very occasionally: 1 g. The small size makes it easier to store and allows you to switch products easily.

You use the flower a few times a month: 3 g. You have enough on hand without necessarily having to stockpile several grams over a long period of time.

You eat it several times a week: 5 g. The relationship between quantity, price per gram, and shelf life becomes interesting.

If you use it regularly and already know how much you need—10 g— buying in bulk can lower the cost per gram, as long as you store it properly.

The right size is the one that fits your frequency of use, your budget, and your consumption habits, while also allowing you to store your flower properly after opening.
