About Us
Boss Hemp.
Dead Straightforward.
We're a Liverpool brand. We source proper hemp, test every batch independently, and put the results where you can actually find them. No gimmicks. Nothing hidden.
What We're About
The UK hemp market's got a lot of brands in it. Most of them are light on detail — vague sourcing claims, no lab reports you can actually find, and product descriptions that tell you next to nothing.
We're not doing that. Calm Leaf is a focused range of hemp flower and CBD solid extract, selected by people who know this category well. Every strain gets assessed before it goes live — cannabinoid profile, terpene character, aroma, trim quality, the lot. Most don't make it.
What's left is what you'll find on the site. Proper stuff, backed by paperwork.

Where the Hemp Comes From
All Calm Leaf hemp is sourced from EU-approved cultivars — varieties registered under the EU Common Catalogue, which sets the legal framework for hemp cultivation across Europe. That's not a nice-to-have. It's the baseline for growing hemp with THC levels that sit within UK law.
We're upfront about how each product is grown. There are three tiers on the site and they mean something:
Premium Indoor
Controlled environment from start to finish. Consistent temperature, humidity, and light cycles year-round. Higher cost to produce, tighter consistency batch to batch. It shows in the profile.
Premium Greenhouse
Natural sunlight, structural protection. A proper middle ground — better consistency than full outdoor, lower production cost than full indoor. Greenhouse growing often produces excellent terpene development from natural UV. Good value for what it is.
Glasshouse, Outdoor & Shake
Full outdoor or semi-outdoor cultivation. More variable by nature — but the right strains grown outdoors develop character that indoor growing doesn't always replicate. We include this tier honestly rather than pretending everything we sell is premium indoor.
EU Cultivar Compliance Every hemp variety we stock is derived from cultivars listed on the EU Common Catalogue of agricultural plant varieties. This ensures THC content stays within the 0.2% threshold set by UK law — verified independently on every batch, not just taken on a supplier's word.
Lab Testing — What Gets Checked and Why
Third-party testing is the only honest way to verify what's in a hemp product. We send every batch to an accredited independent lab before it goes on sale. Not our own lab. Not a certificate from the supplier. An independent one.
Here's what gets tested on every batch:
| Test | What It Checks | Why It Matters |
|---|---|---|
| Cannabinoid Profile | CBD, THC, CBG, CBN, CBC levels by percentage | Confirms THC is within the 0.2% UK legal limit and that stated CBD content is accurate. |
| Heavy Metals | Lead, cadmium, arsenic, mercury | Hemp absorbs what's in the soil. Poor sourcing shows up here fast. Clean soil, clean product. |
| Pesticides & Herbicides | Residual agrochemical screening | EU cultivation standards restrict pesticide use — but testing confirms it independently rather than relying on the grower's say-so. |
| Microbial Contamination | Yeast, mould, E. coli, Salmonella | Storage and handling conditions matter. Clean product throughout the supply chain, not just at source. |
| Moisture Content | Water activity measurement | Affects shelf life and mould risk. Dry and stable means it stays that way in your hands. |
Finding the Reports
Lab reports are linked from the individual product pages. You don't need to ask for them, email us, or fill in a form. They're just there. If a product doesn't have a current report, it's not listed.

Frequently Asked Questions
Is Calm Leaf's hemp legal in the UK?
Yes. Every variety we stock comes from EU-approved cultivars listed on the EU Common Catalogue, and every batch is independently tested to confirm THC stays within the 0.2% UK legal limit. We sell hemp flower as hemp tea — a botanical product for infusion — in line with current UK FSA and MHRA guidelines. See the full breakdown on our compliance overview.
Do you really test every batch, or just some of them?
Every batch, no exceptions. If a product doesn't have a current independent lab report, it doesn't go live on the site. That's not a promise — it's how the catalogue is built.
Where do I find the lab reports?
Linked directly from each product page. No email, no request form, no waiting. If you can't find one, that product shouldn't be listed — let us know and we'll sort it.
What's the difference between hemp tea and CBD solid extract?
Hemp tea is loose flower, sold for brewing or infusion. CBD solid extract (often called hash) is a pressed, concentrated form with a denser aroma and typically higher cannabinoid content per gram — check the individual product's lab report for the exact figure. Both are tested to the same standard.
Do you only deliver in Liverpool?
No — Liverpool is where we're based, not where we stop. Same-day delivery runs daily across all Liverpool postcodes, and next-day tracked delivery covers the rest of the UK. Free standard shipping on orders over £49, free next-day over £79.
Is Calm Leaf an online-only business?
We trade online, but we're not a faceless operation — an actual local team runs this, based in Liverpool. If something's wrong with your order, you'll get a straight answer from a person, not a bot.
Can CBD or hemp tea treat or cure anything?
No CBD brand — Calm Leaf included — can legally claim that. Our products are food supplements, not medicines, and we don't make medicinal claims. If you want the full regulatory position, it's on our compliance overview page.
