Professor Herb Hemp Briquette Hash 3.5g Moonrock Cookies is a heat-pressed block of Italian hemp material infused with terpenes, in a sweet baked-dough flavour. It is also the only ribbon in the fourteen that names a method of building something rather than a plant or a taste, and both halves of the name turn out to come from the same recipe. Nobody selling it explains either half.
A moonrock is a recipe, not a variety
Most cannabis-derived names describe a plant. Moonrock does not. It describes an assembly, and a specific one with three layers.
You start with flower as the base. You dip or coat it in a concentrate, typically a hash oil or distillate. Then you roll the coated bud in kief, the sifted resin powder, so it sets into a dense crust on the outside. The result looks like a lump of rock, hence the name, and every layer after the first exists to add concentrate on top of concentrate.
That is the entire point of the format. A moonrock is a way of stacking so that a finished gram carries far more than the flower it started as. Figures quoted for the THC versions run past fifty per cent by weight, which is why every source describing them frames them as a format for people who already know what they are doing.
To be completely clear, because the name invites the confusion: that is a description of cannabis moonrocks, and this pack is nothing of the sort. It is a pressed hemp product with a stated 175mg in 3.5g. We are explaining where a word came from, not describing what is in the pot.

One pressed material, not three layered ones
The structural difference is worth stating plainly once. A moonrock is three separate materials assembled in sequence, each one added to raise what the finished piece carries. A briquette is a single material heat-pressed into a block, with terpenes and flavourings infused rather than layered.
Neither is a criticism of the other, and they are not competing formats. They are simply built in opposite directions: one by adding concentrate, the other by compressing what is already there. What the material in a briquette actually is, and what the description on these packs claims it to be, is a separate question we have taken on properly on our Forbidden Fruit page.
Why you will not find a CBD moonrock in Britain
This is the obvious follow-up question and nobody in UK CBD retail asks it. Our reading, and we are labelling it as reasoning rather than a legal ruling, is that the format works against the rule it would have to satisfy.
A moonrock exists to multiply what a gram carries. But the test a finished product has to meet in the UK is the total quantity of controlled cannabinoids in the container, counted together. Concentrating the useful part of the plant concentrates everything else along with it, including the trace controlled compounds, so a format whose defining feature is stacking concentration is pushing in exactly the wrong direction for a product that has to keep a total down.
There is a second problem before you even get to that. The base layer is flower, and smokable hemp flower sits outside the industrial hemp cultivation licence, which covers stalk and seed rather than the flowering material. We do not sell CBD flower for that reason. So the bottom layer of the build is already difficult in this market before the other two are applied to it.
Put the two together and the format is hard to produce here in anything like its original form. Which is a reasonable explanation for why the name shows up as a flavour on a pressed briquette rather than as a product in its own right.
| Layer | What it requires | On our shelves |
|---|---|---|
| Base | Smokable flower | No. We sell no CBD flower. Premium Hemp Blend is loose milled material, the nearest thing |
| Coating | A concentrate | Yes: Diamonds and Sauce, CBD Shatter, CBD Crumble |
| Outer crust | Kief, the sifted resin powder | Yes: Euphoria Moroccan Hash is dry sift |
What the flavour is actually like
Given the name, the flavour is more restrained than you might expect. It sits in the baked-goods register rather than the fruit one: sweet dough, a light brown-sugar warmth, and a biscuity note that reads more like shortbread than anything chocolatey.
Underneath there is an earthiness that the fruit flavours in this range do not have, which suits the reference and gives it more grounding than the confectionery profiles. It is closest to Wedding Cake among the ones we stock, but drier and less vanilla-forward, with less of the icing-sugar sweetness.
The pressed hemp base comes through clearly, and in this flavour that works in its favour, because a green resinous note sits naturally alongside a baked one. Of the eight flavours we carry this is one of the two least sweet, which makes it a reasonable choice for anyone who has found the rest of the range too much like a sweet shop.
The aroma out of the pot is warm and slightly savoury at the edges. As with every flavour in this range it carries, so nobody should expect it to be discreet.
Who should pick something else
If the name drew you in because you were looking for the format, this is not it and we would rather say so before you order. It is a flavour reference on a pressed briquette.
If you want something bright and fruity, this is at the opposite end of the range. Pineapple Express or Guava Dog are the tropical options and Forbidden Fruit is the dark-fruit one.
If you want something ready to use as it comes, a briquette is a solid block and has to be broken down first. The loose Premium Hemp Blend is the same material without that step.
If you are buying mainly for the flavour and it will sit for months before you open it, our Gelato page covers what happens to an infused aroma over time and how to slow it down.
Over-18s only. This is not a food and it is not a medicine, and nothing here should be read as suggesting otherwise.
Questions people ask
What is a moonrock in cannabis terms?
A three-layer construction rather than a variety. Flower is used as a base, coated in a concentrate such as hash oil or distillate, then rolled in kief so a dense crust of sifted resin sets on the outside. The purpose is to stack concentrate onto flower so a finished gram carries considerably more than the bud alone, which is why the THC versions are described everywhere as being for experienced users.
Where does the name Moonrock Cookies come from?
Both halves come from the same recipe. The branded moonrock that fixed the term in the market appeared around 2013 to 2014, from the rapper Kurupt and his collaborator Dr. Zodiak, and the original formulation used Girl Scout Cookies flower as its base. So the ribbon names the build and the flower it was built on rather than two separate flavours.
Is the Professor Herb Moonrock Cookies briquette actually a moonrock?
No, and it does not claim to be. A moonrock is three materials layered in sequence. This is one material heat-pressed into a block, with terpenes and flavourings infused into it, and the stated content is 175mg in 3.5g. The name is a flavour reference in the same way every other ribbon in the range is.
Why are CBD moonrocks so hard to find in the UK?
Our reading is that the format works against the rule it would need to satisfy. The build exists to multiply what a gram carries, while the UK test for a finished product is the total quantity of controlled cannabinoids in the container counted together, and concentrating the plant concentrates the trace controlled compounds too. On top of that the base layer is flower, and smokable hemp flower sits outside the cultivation licence, which covers stalk and seed.
Do you sell the parts you would need to build one?
Two of the three. We stock concentrates and we stock a dry sift hash that would serve as the outer layer, but we do not sell CBD flower at all, so the base is missing. The closest thing on our shelves is the loose Professor Herb Premium Hemp Blend, which is milled material rather than whole flower. We are describing what the format requires, not suggesting anyone assemble anything.
What does the Moonrock Cookies flavour taste like?
Baked goods rather than fruit. Sweet dough with a light brown-sugar warmth and a biscuity note closer to shortbread than to chocolate, with an earthiness underneath that the fruit flavours in this range do not have. It is one of the two least sweet flavours we carry, and the pressed hemp base sits naturally alongside it rather than fighting it.
Which briquette flavour is closest to Moonrock Cookies?
Wedding Cake is the nearest neighbour, since both sit in the dessert register rather than the fruit one. The difference is that Wedding Cake is softer and more vanilla-forward with an icing sweetness and a peppery finish, while Moonrock Cookies is drier, more biscuity and noticeably earthier.
Does the Moonrock name mean this is stronger than the other flavours?
No. Every flavour in the briquette range states the same 175mg in 3.5g, and the material underneath is identical across all fourteen ribbons. Only the infused aroma changes between them. If the name suggests extra strength that is an association carried over from a different format entirely, not a claim the manufacturer makes about this one.
