Medium · Use it
A label says “solvent-free.” What is your next question?
See the Medium answer and why
Ask whether the phrase describes the process or a lab result. Then request the relevant process description or batch report.
Budtender practice · Unit 6 OF 8
Understand growing and extraction words
Ask what a production claim actually describes.
Try the first question before reading the lesson. Say your answer aloud or write it down, then open the explanation.
Start with a question
Is CO₂ extraction solventless?
See the Easy answer and why
No. Carbon dioxide can act as a solvent. A different solvent is still a solvent.
Work through the idea
Growing terms and extraction terms describe different parts of a product’s history. For a growing claim, ask what practice the producer means and where it is documented. Avoid turning a broad word such as “natural” into a test result.
For an extract, distinguish solvent-based extraction from physical separation. Pressed rosin is a solventless example. The word guide covers individual solvents, residual results, 90u and terroir. It explains vocabulary, not manufacturing instructions.
Put it into practice
Hard · Explain your judgment
A producer describes its product as living-soil, solventless and 90u. Does that settle quality or medical benefit?
See the Hard answer and why
No. Ask what each term refers to and which records support it. Growing practice, separation method, size marking and medical evidence are different topics. No one label settles all four.
Before moving on
Can you explain the answer in your own words, name one limit, and say what you would check next? If not, revisit the example or look up a word.
This practice does not record a score or award a credential. Every lesson and answer is free to read. No account needed.
