Frequently Asked Questions

What are the specs on the battery?

Our battery is a standard 510 connection and made with stainless steel, coated in rubber. We recommend using GRB batteries with our cartridges because of the unique airflow design, which may not be compatible with other batteries.

What is included in my GRB vape kit?

Every GRB vape kit comes with a cartridge, battery, strain band, and charger.

How do I charge my GRB battery?

Please only use the charger that came with your GRB battery.

Simply screw the battery into the charger, then plug the charger into any USB adapter (such as a laptop or wall outlet).

What do you mean “control the experience”? How do I do that?

Our pens come with a variable airflow, which means you can control how big your cloud will be. If you cover the airholes, you will have a bigger cloud but less flavor. Leaving the airholes uncovered means there will be a smaller, tastier cloud.

Do you have any future products in production?

We are always developing new products and formulations. Our Rocket 1 gram hardware will be launching in 2018, and we have more surprises lined up as well!

What size carts do you offer?

We offer both the standard 500mg as well as the ‘Rocket’, a premium 1 g cartridge which will be launching in 2018.

A lot of companies have been caught with myclobutanil and butane left in their products. I don’t want my medicine to give me health conditions; how can I be sure that GRB is taking this problem seriously?

GreenRock completes a full spectrum pesticide and contaminant screen so that we can be confident in the products we sell. You can see our results at SCLABS.COM

How do you process your oils?

After a CO2 extraction, we then distill our oil using either shortpath or thin film processes to ensure the consistent quality associated with GRB products.

How strong is your oil?

While exact strengths will vary by batch (our oils are coming from a plant, after all!) they tend to sit above 70%- consistent with pure cannabis oil.

Where are the air intakes for the GRB pen?

The GRB pen has four holes on top near the mouthpiece and two on the bottom where the cartridge and battery connect. If you hold the pen in different ways, it can give you a different type of hit.

What material is the tank made out of?

GreenRock uses stainless steel tank with a durable quartz crystal chamber wrapped in a branded matte rubber exterior. This combination helps to ensure that our pens provide superior performance, with less breakage and a tighter grip for our consumers.

I’ve had lots of vape pens break- how durable are GreenRock products?

Because of our high manufacturing standards, we can personally guarantee each and every GRB cartridge and pen. If there’s a defect, just bring it back to your clinic and have it swapped out- free of charge.
