What Makes Terps USA® Different

Most terpene sprays on the market ship with a plastic pump stem stored inside the bottle. Terpenes are lipophilic solvents — they actively break down plastic on contact. Every day that stem sits submerged in your concentrate, it leaches plasticizers directly into the product. You taste plastic because the delivery method is plastic.

The Spray Master uses no plastic in contact with the terpenes. Air pressure only. Pure terpene reaches your flower the way it was meant to — clean, atomized, and controlled.

How to Use Terpene Spray

Start with 1 to 2 drops or 1 to 2 sprays per gram of flower. Less is always more on the first application — you can add, but you cannot remove. Apply with the Spray Master at 6 to 10 inches from the surface using smooth, sweeping passes. Allow the flower to rest 15 to 20 minutes before sealing. The profile will continue to develop and settle over the next several hours.

For dry or older flower that has lost its terpene content, start at the lower end of the dosing range. The flower will absorb more readily than fresh material.

For bulk or commercial application, see the full dosing reference table in the Ultimate Terpene Spray Guide.

Strain Profiles and Fruit Flavors

Terps USA® offers fourteen botanical terpene spray formulas — strain-specific profiles and fruit flavor options. Strain profiles are formulated to match the terpene character of the named cultivar. Fruit flavors are designed to layer cleanly on top of any strain base without masking the underlying cannabis character.

Strain profiles include: Fruity Cereal, OG Kush, Gelato, Sour Diesel, Girl Scout Cookies, Strawberry Cough, Pineapple Express, and more.

Fruit flavors include: Blueberry, Strawberry, Grape, Banana, Mango, and Pineapple.

For custom layering and combination ratios, the Terpene Alchemist guide includes over 60 tested recipes.

The Research Behind the Product

Terps USA® is the only terpene spray brand with DOI-indexed, ORCID-verified research published on Zenodo and independently curated in the CannabisScience IQ academic collection — a research community hosted by CERN and managed by the Central University of Ecuador.

Our published research covers botanical terpene application protocols, PG and PEG combustion safety, and the science of why carrier oils and aerosol propellants are the real avoidable risk in terpene enhancement. No other terpene spray brand has published research at this level on what goes into their product and why.

Frequently Asked Questions

Is terpene spray safe to smoke?

Terps USA® terpene sprays contain 100% botanical terpenes — the same compound class found naturally in cannabis flower. They contain no propylene glycol, no polyethylene glycol, no Vitamin E acetate, and no aerosol propellants. The combustion chemistry of pure botanical terpenes mirrors the natural terpene profile of the flower itself.

Will terpene spray change the effects of my flower?

Botanical terpenes may contribute to the overall experience through the entourage effect, but they do not increase THC content or alter the pharmacological profile of the cannabinoids in your flower.

How much terpene spray should I use?

Start with 1 to 2 sprays per gram. Allow 15 to 20 minutes of rest time before sealing. Adjust up or down based on your preference. The full dosing table is in the Ultimate Guide.

What is the Spray Master?

The Spray Master is a precision air-pressurized terpene applicator. It atomizes the terpene into a fine mist using air pressure only — no propellants, no plastic contact with the product. It is the only professional-grade terpene spray applicator designed specifically for cannabis flower.

Why does my terpene spray taste like plastic?

If your terpene spray tastes like plastic, the most likely cause is the delivery method — not the terpenes themselves. Plastic pump stems stored inside terpene bottles leach plasticizers into the concentrate because terpenes are lipophilic solvents that actively break down plastic. Terps USA® Spray Master uses air pressure only, with no plastic in contact with the product at any point.
