How Much THCA Flower Should You Buy? Grams, Ounces, and Pounds Explained

The right amount of THCA flower depends on three things: how often you typically reorder, how much variety you want, and how long the flower will spend in storage. Sizes run from a single gram up to bulk quantities, and the cost per gram typically falls as the size goes up.
The most common larger purchase is the THCA ounce. A standard ounce is 28.35 grams, and most cannabis retailers sell ounces as 28 grams. Black Tie uses a 30-gram ounce for its full-size flower instead, which is why it pays to compare the listed gram weight, not just the word "ounce," when shopping between sellers.
This guide covers every common size from a gram to a pound, what each one converts to, and the questions that decide which size fits how you shop. If you'd rather browse by strain first, the THCA Flower collection lists the sizes offered for each product.
THCA Flower Sizes at a Glance
| Size | Grams | Share of an ounce | Typical purchase |
|---|---|---|---|
| Gram | 1 g | About 1/28 oz | Trying a strain, samplers |
| Eighth | 3.5 g | 1/8 oz | Trying a new strain |
| Quarter | 7 g | 1/4 oz | Getting to know a strain |
| Half ounce | 14 g | 1/2 oz | Splitting a budget across two strains |
| Ounce | 28 g standard retail; 30 g at Black Tie | 1 oz | Lower cost per gram |
| Quarter pound | About 113 g | 4 oz | Stocking up on a strain you already know |
| Half pound | About 227 g | 8 oz | Larger bulk quantity |
| Pound | About 454 g | 16 oz | Bulk and wholesale purchases |
Quarter-pound, half-pound, and pound weights above are standard conversions. Retail packaging can use different gram quantities for products labeled by weight, so check the listed weight on each product page. In standard measures, a pound holds 16 ounces, or 128 eighths. A quarter pound holds 32 eighths, and a half pound holds 64.
How Many Grams Are in an Ounce of THCA Flower?
A standard ounce is 28.35 grams. Retail cannabis sizes are usually rounded for simplicity: an eighth is sold as 3.5 grams, a quarter as 7 grams, a half ounce as 14 grams, and an ounce as 28 grams. In those standard measures, an ounce equals eight eighths or four quarters.
Black Tie uses a 30-gram ounce for its full-size flower rather than the conventional 28-gram retail measure. Because sellers don't all measure an ounce the same way, the number on the label matters more than the name of the size. Black Tie lists the weight with each size on its product pages. When you compare options, divide the price by the listed grams to get a true cost per gram.
What Changes as You Buy More
Black Tie's larger quantities are larger-format purchases of selected strains, with availability varying by product and size. What changes as you move up in size is:
- Cost per gram. Larger sizes typically cost less per gram, and the difference grows at quarter-pound and bulk quantities.
- How often you reorder. A larger size means fewer orders to place and track.
- How long the flower sits. More flower takes longer to use, which makes storage more important.
- How much variety a budget buys. One large size of a single strain covers less variety than smaller amounts of several.

How to Decide How Much THCA Flower to Buy
How often do you reorder?
Consider how quickly you typically reorder. Larger quantities can reduce cost per gram, but they also remain in storage longer, so the best value depends on how quickly you expect to use the product while maintaining freshness.
Do you already know the strain?
A strain you haven't tried is a different purchase from one you already know you like. Smaller sizes are a lower-commitment way to try something new, and sampler packs of 1-gram portions, like the Indoor sampler and the Light Dep / Light Assist sampler, let you try several strains at once. Larger sizes fit best around a strain you already know.
How much variety do you want?
If you like rotating between strains, splitting a budget across smaller amounts of several strains may suit you better than one large size of a single strain. Two half ounces of different strains add up to about the same weight as one ounce, usually at a slightly higher cost per gram than a single ounce would carry.
Buying THCA Flower by the Ounce
The ounce is the most common step up from smaller sizes, and it's where many shoppers first see a meaningful drop in cost per gram. Black Tie's full-size THCA ounces contain 30 grams, compared with the 28-gram measure commonly used by cannabis retailers. When comparing an ounce between sellers, compare the actual listed gram weight rather than the word "ounce" alone.
Black Tie offers THCA ounces in three formats:
- Full-size flower, available by strain across the THCA Flower collection.
- THCA MINIS, whole, intact buds that are naturally smaller than standard flower, offered at a lower cost per gram.
- THCA Trim/Shake, smaller flower fragments and sugar leaf material separated during trimming, offered at a lower cost per gram.
MINIS and Trim/Shake are different products, not smaller versions of each other.
For a recurring supply without choosing each strain yourself, the Budtender's Choice subscription lets you set the production type and quantity while Black Tie's team selects the strains, delivered on a schedule you choose.
Quarter Pounds, Half Pounds, and Pounds of THCA Flower
Using standard weight conversions, a quarter pound is 4 ounces (about 113 grams), a half pound is 8 ounces (about 227 grams), and a pound is 16 ounces (about 454 grams). Retail cannabis packaging can use different gram quantities for products labeled by weight, so always check the listed weight.
Black Tie's Bulk THCA Flower collection offers larger quantities of selected strains available elsewhere in the catalog. What changes is the price per gram. Exotic, Indoor, and Light Dep / Light Assist flower is offered in quarter-pound quantities on select strains, while Greenhouse flower extends to half-pound and, on some strains, full-pound sizes. Each product page lists the sizes currently offered for that strain.
If you need more than a listed size, contact Black Tie directly, since additional quantity may be available beyond what's shown on the site. Retailers and other businesses buying on an ongoing basis can apply through the Wholesale Registration page.
Storing Larger Quantities of THCA Flower
The more flower you buy at once, the more storage matters. Keep it in an airtight container, away from direct light and excessive heat, to help preserve aroma, texture, and overall condition. Open the container only when you need to, and where a product page lists a harvest date, use it as a reference for how recently that batch came in.
Check the Lab Results Before a Larger Purchase
Black Tie flower products link to third-party Certificates of Analysis on their product pages, with each COA reflecting a specific batch. Before committing to a larger size, it's worth reviewing that batch's COA for its cannabinoid results. Black Tie's full set of reports is on the Lab Results page.
FAQs About Buying THCA Flower
How many grams are in an ounce of THCA flower?
A standard ounce is 28.35 grams, though cannabis retailers commonly sell ounces as 28 grams. Black Tie's full-size flower ounces contain 30 grams, so check the listed weight when comparing sellers.
How many eighths are in an ounce?
In standard retail measures, eight. An eighth is 3.5 grams, so eight eighths make a 28-gram ounce. By the same standard conversions, a quarter pound contains 32 eighths and a pound contains 128.
How many grams is a quarter pound of THCA flower?
Using standard conversions, a quarter pound is 4 ounces, or about 113 grams. Check the listed weight on the product page for the exact amount.
Is a larger size cheaper per gram?
Typically, yes. Cost per gram tends to fall as the size increases. Each product page shows current pricing for every size, so you can compare cost per gram directly.
What's the difference between THCA MINIS and Trim/Shake?
MINIS are whole, intact buds that are naturally smaller than standard flower. Trim/Shake consists of smaller flower fragments and sugar leaf material separated during trimming. Both are offered at a lower cost per gram than full-size flower.
Can I buy more than the largest size listed?
Contact Black Tie directly about larger quantities, since additional inventory may be available beyond what's listed. Businesses buying on an ongoing basis can apply for the wholesale program.
The Bottom Line
There's no single right size of THCA flower. The ounce is the most common step up, quarter pounds and bulk sizes lower the cost per gram further, and smaller sizes and samplers make it easy to try something new. The size that fits is the one that matches how often you reorder, how much variety you want, and how well you can store it. At each size, the product page provides batch-specific information and a COA, so you can compare the actual product as well as the quantity before buying.
