Hemp Flower 101: Beginner's Guide
Posted by Emerald Medicine Company on Mar 31st 2026
Never bought hemp flower before? No worries. This guide covers what hemp flower actually is, the difference between THCa-dominant and CBD-dominant strains, what to look for on a lab report, and how to keep it fresh once you get it home. Straight from our Durham hemp shop team — no jargon, no pressure.
What Is Hemp Flower?
If you're new to the world of hemp, you might be surprised to learn that hemp flower is one of the most popular product categories in shops like ours. Simply put, hemp flower refers to the dried, cured buds of the hemp plant — the part that's rich in cannabinoids like THCa and CBD.
Unlike CBD oil or edibles, hemp flower is the raw plant material itself. When you open a bag of quality hemp flower, you'll notice the aroma, the texture, and the care that went into growing and curing it. It's a craft product, and the details matter.
Hemp flower comes in a wide range of strains, each with its own cannabinoid profile and terpene signature. Some strains are high in THCa, others are CBD-dominant, and many fall somewhere in between. Understanding this spectrum is the first step to finding what works for you.
THCa Flower vs CBD Flower
Not all hemp flower is created equal, and the two main categories you'll encounter are THCa-dominant and CBD-dominant flower.
THCa flower is bred to produce high levels of tetrahydrocannabinolic acid. These strains typically test at 15–25% THCa or higher, with lower CBD content. When heated, the THCa converts to Delta-9 THC. This is what most customers are looking for when they browse our hemp flower selection.
CBD flower is bred to maximize cannabidiol content while keeping THCa levels low. These strains appeal to customers who want the cannabinoid profile of flower without the conversion to THC that comes with heating.
Between these two ends, there are balanced strains that offer meaningful amounts of both cannabinoids. The key is to check the Certificate of Analysis — the COA tells you exactly what's in the flower you're buying.
Reading a Hemp Flower COA
A Certificate of Analysis (COA) is a lab report from an independent testing facility. For hemp flower, here's what to look for:
- THCa % — The dominant cannabinoid in most flower. This is the number that indicates potential potency after heating.
- CBD % — Cannabidiol content. Higher in CBD-focused strains.
- Moisture Content — Should be between 10–15%. Too high means risk of mold; too low means dry, harsh flower.
- Total Cannabinoids — The total cannabinoid content after accounting for standard conversion factors. This applies the decarboxylation conversion (THCa × 0.877 = THC, CBDa × 0.877 = CBD) and reflects what you’d expect once the product is heated and consumed.
- Sum of Cannabinoids — The raw total of all cannabinoids added together before any conversion calculations. This is a higher number than Total Cannabinoids and represents what’s present in the flower before heat or processing. Useful as a quick snapshot of overall cannabinoid density in the plant.
- Contaminant Testing — Should show passing results for pesticides, heavy metals, microbials, and mycotoxins.
We always have COAs available for our products. If you're shopping in-store, just ask — we're happy to walk you through the results.
THCa, CBD, and What Happens When You Combine Them
Understanding the difference between THCa and CBD — and how they work together — helps you shop smarter and get more out of your hemp flower.
THCa (High-THCa Flower)
THCa is the dominant cannabinoid in most hemp flower sold today. When heated through smoking or vaporizing, THCa converts to Delta-9 THC, which produces the well-known psychoactive effects most people associate with cannabis: relaxation, euphoria, altered perception, and relief from stress or discomfort. THCa flower is best suited for experienced users looking for a full, potent effect.
CBD (CBD-Dominant Flower)
CBD flower contains high levels of cannabidiol with minimal THCa. CBD is non-intoxicating, meaning it won’t produce a high. It’s associated with a calming, grounding effect — many people use it for stress relief, physical relaxation, or unwinding without any psychoactive experience. CBD is also a good starting point for people who are new to hemp and want to ease in.
Combining a THCa Strain with a CBD Strain
Here’s where it gets interesting: pairing a THCa-dominant strain with a CBD-dominant strain in the same session tends to offer a more balanced, rounded experience than either one alone. CBD can soften the more intense effects of THC — reducing anxiety or overstimulation while still allowing the relaxing and euphoric qualities to come through. This is sometimes called the entourage effect — the idea that cannabinoids work better in combination than in isolation.
If you enjoy THCa flower but occasionally find the effects a bit much, try mixing in some CBD flower in the same bowl or joint. The CBD doesn’t cancel out the experience — it rounds it out. Conversely, if CBD alone doesn’t feel like enough, adding a small amount of THCa flower into the mix can take it to the next level. Our staff can help you find a good pairing from our current selection.
What to Look for When Buying
Whether you're a first-timer or a regular, these quality indicators will help you choose well:
Quality Checklist
- Trim: Well-manicured buds with minimal stems and leaves
- Color: Vibrant greens with purple or orange accents — avoid brown or yellowed flower
- Smell: Strong, fresh aroma. If it smells like hay or nothing at all, it's likely stale
- Texture: Slightly sticky but not wet. Should spring back when gently squeezed
- COA available: Always ask for or check the lab report before buying
- Source: Look for flower grown and processed by reputable farms with transparent practices
Storing Hemp Flower
Proper storage makes a real difference in how long your flower stays fresh and how it performs. Here are the four key factors:

Frequently Asked Questions
Hemp flower comes from cannabis plants legally defined as containing 0.3% Delta-9 THC or less by dry weight. It's a distinct legal category, and hemp flower is sold legally in North Carolina through licensed hemp retailers.
That depends on how often you use it and how you store it. For freshness, we recommend buying quantities you'll use within 2–4 weeks. Properly stored flower can maintain quality for several months.
Loose flower is whole or broken-up buds sold by weight. Pre-rolls are pre-made for convenience. Smalls are smaller buds from the same plant — same quality, lower price point, great value.
Yes. We have lab results available for all our flower products. Ask in-store or check the product listing on our website.
We do. Our selection includes both THCa-dominant and CBD-dominant strains. Ask our staff to point you toward whichever profile you're looking for.
