Do-Si-Dos Seeds

The feminized version — available from Homegrown Cannabis Co and ILGM — is the most widely purchased format and gives you the full yield potential of the Girl Scout Cookies x Face Off OG genetics, with indoor yields up to 500g/m² and outdoor yields reaching 800g per plant on an 8–9 week flower cycle. Regular seeds, stocked by Seedsman, produce both male and female plants and are intended for breeders working with Do-Si-Dos genetics rather than production growers. Autoflower seeds from Zamnesia or Royal Queen Seeds complete their cycle in 8–10 weeks from seed regardless of light schedule, with a moderate yield trade-off compared to the photoperiod versions. Your choice comes down to whether you're growing for maximum output, breeding, or prioritizing a faster, more flexible schedule.

Do-Si-Dos is verified at 20%–30% THC, placing it firmly in the upper tier of commercially available high-THC seeds. That range reflects genuine variation between phenotypes and growing conditions, so if hitting the top of that bracket matters to you, compare lab-tested batch results across seedbanks before purchasing. ILGM and Royal Queen Seeds both publish detailed strain data that can help you assess which source is consistently producing the higher-THC phenotypes. CBD content is insignificant, so this strain is not suited to CBD-focused buyers.

Do-Si-Dos is rated beginner-friendly, which is notable given its 20%-30% THC potential and the complexity of its GSC x Face Off OG lineage. From a buying perspective, this means you're not paying a specialist premium for seeds that require advanced management — the genetics are stable and forgiving enough for first-time growers to achieve solid results. If you're a beginner comparing indoor seeds in the high-THC indica category, Do-Si-Dos represents a lower-risk entry point than many comparable strains at a similar price per seed.

Do-Si-Dos seeds are currently available from five seedbanks: Homegrown Cannabis Co (feminized), ILGM (feminized), Seedsman (regular), Zamnesia (autoflower), and Royal Queen Seeds (autoflower). For buyers in North America, Homegrown Cannabis Co and ILGM offer domestic-friendly shipping and strong germination guarantees. European buyers will find Seedsman, Zamnesia, and RQS more competitive on shipping costs and delivery times. Before you buy Do-Si-Dos seeds, check current pack sizes — these vary from 3-seed to 10-seed packs depending on the seedbank — and look for active crypto payment discounts, which can reduce your per-seed cost meaningfully across all five suppliers.
