Critical Mass Seeds: Frequently Asked Questions
What THC level can I expect from Critical Mass seeds?
Critical Mass feminized seeds are tested up to 22% THC, which places this strain in the moderate-high potency bracket for indicas. That ceiling is achievable under optimized indoor conditions; outdoor grows and less controlled environments typically land in the 17–20% range. The Afghani side of the lineage drives the heavy physical effect profile at these THC levels, so buyers sensitive to strong body effects should account for that when choosing between Critical Mass and lighter indica options.
Is Critical Mass a good strain for beginner growers?
Critical Mass carries an easy difficulty rating, which is one of the reasons it remains a consistent bestseller across all eight seedbanks that stock it. The Afghani genetics give the plant natural resilience, and the 8–9 week flowering window is short enough to reduce the exposure window for common beginner mistakes. For first-time buyers, ILGM's germination guarantee and Crop King Seeds' customer support structure (score: 7.2/10) make both solid starting points specifically for this strain.
Is Critical Mass worth the price compared to similar strains?
At 400–600g/m² indoors and up to 700g per plant outdoors, Critical Mass delivers yields that outpace Northern Lights (typically 400–500g/m²) and match Big Bud, while adding a THC ceiling of 22% that Big Bud rarely reaches. The 8–9 week flowering time also means you recover your investment faster than with slower heavy-yielding indicas that run 10–11 weeks. For buyers prioritizing grams-per-watt efficiency alongside potency, Critical Mass offers one of the stronger value combinations available in the easy-difficulty indica category.
Where can I buy Critical Mass seeds online?
You can buy Critical Mass seeds from Seedsman, ILGM, Crop King Seeds, Homegrown Cannabis Co, Herbies Seeds, Royal Queen Seeds, Barney's Farm, and Seed City. ILGM (7.4/10) and Crop King Seeds (7.2/10) hold the strongest buyer scores for this strain specifically. If you want to buy Critical Mass feminized seeds from the original breeder, Barney's Farm is the source, though their strain-specific score of 4.5/10 suggests checking recent batch reviews before ordering. Herbies Seeds and Seed City are practical choices if you're consolidating a multi-strain order.
