Live Resin Cart 2mL — One Per Blend
The blend line. Each of the ten Mellow Fellow blends appears once, paired with a strain. Live resin is extracted from fresh-frozen hemp, which keeps more of the strain's original terpene profile than distillate does.
Premium Cart 2mL — A Second Strain Per Blend
Same 2mL size and the same blend names, different strains. If you already know your blend and want a change of flavor, this is where to look.

Candyland is the best-selling cart in this collection, at roughly double the next one.
THC-P Cart 0.5G — The Most Concentrated
A smaller 0.5G cartridge built around THC-P rather than a mood blend. THC-P binds CB1 receptors far more readily than Delta-8 does, so this is the line to approach carefully and the one to skip if you are new to these products. Five strains: Blueberry Muffins, Cereal Milk, Darkstar, Juice Box and TKO.
Delta-8 and Delta-10 Carts 1mL — The Entry Lines
Single-cannabinoid cartridges without the blend system. Straightforward, and the cheapest carts we carry.
Delta-10 at $13.95 — Purple Punch, Sour Diesel, Strawberry Cough and Zkittlez. Delta-10 tends to sit at the more alert end than Delta-8.
Delta-8 at $21.95 — Pineapple Express, Purple Punch and Wedding Cake.
Duo Live Resin Cart 4mL
A dual-chamber 4mL cartridge pairing two strains in one cart, at $38.95. Available in Cali Gas & Forbidden Fruit, King Louis & Blue Dream, Pineapple Express & MK Ultra, Tahoe OG & Strawberry Amnesia, and Tres Leches & Bubba Kush. Stock on this line is limited.
What Battery Do I Need?
Any standard 510-thread battery fits every cart in this collection. If your battery has variable voltage, keep it at the lower end — live resin and terp-based extracts taste better and last longer at low heat, and high settings burn the coil and flatten the flavor.
Screw the cart on until it is snug, not tight. Overtightening is the most common cause of a cart that will not fire. Store it upright at room temperature.

Frequently Asked Questions:
How much is a Mellow Fellow cart?
Between $13.95 and $38.95 at DeltaCloudz, depending on the line. Delta-10 1mL is $13.95, the Live Resin and Premium 2mL carts are $19.95 to $21.95, Delta-8 1mL is $21.95, THC-P 0.5G is $32.95, and the Duo 4mL is $38.95.
Are Mellow Fellow carts THCA?
No. Mellow Fellow carts are built on Delta-8 THC and blend cannabinoids — THC-P, THC-B, Delta-10, CBN, CBG and CBD depending on the line. They are not THCA products. If you are specifically after THCA, that is a different category from this collection.
What is the strongest Mellow Fellow cart?
The THC-P Cart 0.5G is the most concentrated in THC-P, which is the cannabinoid that changes the experience most at small percentages. Among the blend carts, Dream and Introvert are the heaviest. There is no single strongest — compare the COA on each product page rather than going by the name.
Are Mellow Fellow carts legit?
Yes. Every cart carries a third-party Certificate of Analysis covering cannabinoid potency, Delta-9 THC content, pesticides, heavy metals and residual solvents. The real risk in this category is counterfeits rather than the genuine product — scan the QR code and check it resolves to a batch-specific report. More on this in our guide to whether Mellow Fellow is safe.
What battery works with Mellow Fellow carts?
Any 510-thread battery. For live resin, use a variable-voltage battery on a low setting. Browse our 510 batteries.
Cart or disposable — which should I buy?
A cart needs a battery but lets you swap strains on the same device and costs less per millilitre over time. A disposable is ready out of the box with nothing to buy alongside it. Same blends either way.
Do Mellow Fellow carts show on a drug test?
Assume yes. Standard tests detect THC metabolites and do not distinguish Delta-8 from Delta-9. If you are tested for any reason, these are not a safe choice.
