How to Choose Your Strain — 5 Key Questions
- What time of day are you consuming?
Daytime → sativa or sativa-dominant hybrid (Amnesia Haze). Evening → indica or indica-dominant (Permanent Marker, Wedding Cake, Grand Daddy Purp). Any time → balanced hybrid at moderate THC (Runtz, Gelato 41).
- What is your tolerance level?
New or low tolerance → stay at 18–22% THC. Try Zkittlez or Blue Cheese. Experienced → 25%+ strains like Permanent Marker and Atomic Apple are appropriate. Always start with a small amount regardless.
- What are you trying to achieve?
Sleep → Grand Daddy Purp, Biskante. Focus/creativity → Amnesia Haze. Stress relief → Wedding Cake, Runtz, Gelato 41. Maximum relaxation → Permanent Marker. Social mood lift → Runtz, Gelato 41.
- Do you have anxiety concerns?
Prioritise strains high in Linalool and Caryophyllene — both have documented anxiolytic properties. Blue Cheese, Gelato 41, and Runtz are well-suited. Avoid very high-THC pure sativas without terpene balance if you are anxiety-prone.
- Do you prioritise flavour or potency?
Flavour-first → Amnesia Haze (sharp citrus), Atomic Apple (fresh fruit), Runtz (candy), Gelato 41 (cream). Potency-first → Permanent Marker, Atomic Apple. Both → Permanent Marker delivers extraordinary terpene complexity alongside maximum THC.
Understanding THC Percentages — A Realistic Guide for Australian Buyers
THC percentage is the most cited metric in cannabis — and also the most misunderstood. Here is what the numbers actually mean in practice.
Terpenes — Why Two Strains at the Same THC Feel Completely Different
THC percentage tells you how strong a strain is. Terpenes tell you what kind of experience you'll have. Two strains at 25% THC can feel radically different based entirely on their terpene profile. This is the knowledge that separates experienced cannabis enthusiasts from beginners.
