How To Test THC Levels on Weed Plants

When using weed, it’s important to know how to test THC levels (tetrahydrocannabinol) in your weed for a personalized and safe experience. This guide will help you in THC testing, explore various methods how to measure THC in homegrown weed and assist in identifying the optimal THC percentage for preference. Understanding the strength of THC in your weed is essential for a safe and secure experience, and this guide simplifies the process by breaking down all there is to know when you test THC levels in buds and offering practical insight.

How To Measure THC Level

In areas where cannabis is legal, growers must go through THC testing to provide accurate information about THC percentages to consumers. Labels often show both THC and THCa percentages. THCa, the precursor to THC, changes when exposed to heat or combustion. Figuring out the total THC in your cannabis requires a detailed equation.
(0.75 × 0.877 × % THCA) + % THC = Total THC in flower
Comprehending this conversion process enhances the precision of interpreting THC content in your cannabis.

Types of Testable Cannabis Products

Technological advancements have broadened THC testing capabilities, now including a variety of cannabis products. Beyond the traditional cannabis flower, testing now extends to:

  • Cannabis edibles
  • Cannabis concentrates
  • Cannabis oil


Accurate THC measurements across diverse consumption methods require specific testing methodologies for each product category.

DIY Methods for Measuring THC

How To Test THC Levels

Color Chart Test Kits

Affordable and easy to use, color chart test kits provide a simple method for THC measurement. These kits require placing a small sample of your cannabis flower into a container with a testing solution. The resulting color change can be matched to a provided chart, giving a visual representation of THC levels.

Thin-Layer Chromatography (TLC) Test Kits

Though more expensive than color chart kits, TLC (thin-layer chromatography) test kits offer a more comprehensive analysis. These kits go beyond THC, revealing other minor cannabinoids, providing a holistic view of the chemical composition of your cannabis. The process involves saturating the flower with a liquid, separating individual cannabinoids, and applying a dye to showcase their percentage.

Testing Gadgets

For dedicated enthusiasts or cultivators, high-end testing gadgets provide precise readings of cannabinoid levels. These devices, often priced at over $800, are connected to smartphones, offering a detailed chart post-analysis.

Determining the Right THC Percentage

Equipped with THC knowledge, choosing the right percentage becomes a crucial decision. Cannabis flower usually has 10-30% THC, and beginners are often recommended to begin in the 10-15% range. However, the significance of personal tolerance cannot be emphasized enough. Starting with a small puff allows beginners to assess the effects before adjusting the dosage according to their individual preferences.


Gaining proficiency in THC measurement empowers cannabis consumers to make informed choices, guaranteeing a safe and enjoyable experience. This comprehensive guide, ranging from unraveling the intricacies of THC testing science to exploring various DIY testing methods, equips you to navigate the cannabis landscape with confidence. Remember, the pursuit of THC knowledge isn’t just about potency; it’s about crafting an experience tailored to your unique preferences.


Q: Can I use the same THC testing methods for edibles as I do for cannabis flowers?
A: No, different cannabis products require specific testing methods. While color chart test kits may work for flowers, edibles, concentrates, and oil often require specialized testing.

Q: Are at-home THC testing kits accurate?
A: Yes, at-home THC testing kits, when used correctly, can provide reasonably accurate results. However, for precision, professional testing labs remain the gold standard.

Q: What’s the significance of THCa in THC testing?
A: THCa is the acidic precursor to THC, and its percentage is crucial for understanding the total THC content upon combustion. Calculating both THC and THCa provides a more accurate dosage estimation.

Q: Can high THC levels in cannabis have adverse effects?
A: Yes, high THC levels can lead to stronger psychoactive effects, potentially causing discomfort for inexperienced users. It’s advisable for beginners to start with lower THC percentages.

Q: Is there a universal recommended THC percentage for all cannabis consumers?
A: No, the ideal THC percentage varies among individuals. Beginners often start with 10-15%, but personal tolerance and preferences play a significant role in determining the right THC level for each person.
