The Full THC Watermelon Agua Fresca Recipe
Ingredients
- 2 cups fresh seedless watermelon, cubed
- 1 cup cold water
- Juice of 1 lime
- 1 scoop Halo THC Drink Mix (10mg)
- Ice
- Instructions
Add the watermelon, cold water, and lime juice to a blender. Blend until smooth. If you prefer a smooth, juice-like consistency, strain through a fine mesh strainer. If you like a little body, skip the strainer.
Pour into a glass, add one scoop of Halo THC Drink Mix, and stir for 10 seconds until dissolved. Add ice and enjoy. The whole process takes less than three minutes, and most of that is the blending.
Why Watermelon Is the Perfect THC Base
Watermelon is over 90% water. That makes it naturally hydrating and one of the smoothest fruits to blend into a drink. It does not need added sugar because ripe watermelon is already sweet enough to stand alone. And the mild, clean flavor does not compete with anything, which is exactly what you want when your THC mix is designed to be invisible.
Agua fresca is a Mexican drink tradition built around fresh fruit, water, and a little citrus. It has been the smarter alternative to sugary sodas and heavy drinks for generations. Adding Halo THC Drink Mix to the glass just extends that idea one more step. Same simplicity. Same refreshment. A better buzz built in. That is what makes a THC watermelon drink like this one feel so natural.
The lime is important. It keeps the watermelon from tasting flat and adds a brightness that makes the whole drink pop. Do not skip it.
Batch It for a Cookout
This recipe scales perfectly. For eight servings, blend a small seedless watermelon (about 16 cups cubed) with 8 cups of cold water and the juice of 4 limes. Strain into a large pitcher or drink dispenser.
Add 8 scoops of Halo THC Drink Mix (80mg total, 10mg per serving) and stir thoroughly. Each 8-ounce glass will deliver a consistent 10mg dose. Label the pitcher clearly and keep it on ice.
This is one of the best drinks to bring to a cookout because it looks great, tastes like summer, and replaces the cooler full of beer without anyone feeling like they are missing out. It also costs a fraction of what a premixed THC beverage runs per serving.
Dosing Guidance
One scoop of Halo THC Drink Mix delivers 10mg of hemp-derived, water-soluble THC. For most adults with THC experience, 10mg is a comfortable dose for a social setting. If you are newer to THC beverages, start with half a scoop (5mg) and wait 30 minutes before having more.
Water-soluble THC absorbs faster than traditional edibles. Most people report onset within 10 to 20 minutes. The experience is typically smoother and shorter-lasting than a gummy or oil-based edible. Individual results vary based on tolerance, body weight, and recent meals.
Halo THC Drink Mix is legal under the 2018 Farm Bill for hemp-derived products. State laws on hemp THC vary. Check your local regulations. All Halo products are third-party lab tested with COAs available at drinkhalo.com.

Frequently Asked Questions
Do I need to use fresh watermelon?
Fresh watermelon tastes the best, but frozen watermelon chunks work too and give the drink a slushie-like consistency without needing extra ice. If using frozen, reduce the water to three-quarters of a cup so the drink does not get too thin as the watermelon melts.
Can I add other fruit to the agua fresca?
Absolutely. Cucumber and mint are classic additions that keep things light. Strawberries or mango blend well with watermelon too. Just keep the total volume close to the original recipe so your THC dose stays proportional to each serving.
How long does THC watermelon agua fresca last in the fridge?
Best within 24 hours. Fresh watermelon juice starts to lose its brightness after a day. If you batch it for a group, make it the morning of the event and keep it cold. Stir before serving to redistribute the THC evenly.
