Do-Si-Dos Cookies Feminized Seeds by 00 Seeds – Indica-Dominant Hybrid with 23% THC & Sweet Earthy Flavor

Do-Si-Dos Cookies feminized seeds by 00 Seeds give you a premium indica-dominant hybrid that delivers big yields, fast finishes, and a blissful high—perfect for turning your grow space into a relaxation zone.

Struggling with weak yields and bland flavors?

You’ve tried other GSC crosses, but they fall short—either too slow, too finicky, or just not potent enough. You want a strain that hits hard, smells amazing, and fills your jars without wasting time or space.

Why keep settling for average when you can grow legendary?

Most photoperiod strains take forever to finish, drain nutrients, and still underdeliver. You’re left with airy buds, weak effects, and wasted electricity. And if you’re growing discreetly, long cycles and strong odors are a no-go. You need something that respects your time, your setup, and your taste.

Do-Si-Dos Cookies delivers the full package—fast, frosty, and flavorful

Bred from two California royalty lines—Girl Scout Cookies and Face Off OG—this feminized powerhouse packs 23% THC and finishes flowering in just 50–55 days. Indoors, it yields 500–550 g/m² (1.64–1.80 oz/ft²) of dense, trichome-coated buds with a sweet, earthy aroma and subtle minty freshness. At 80–100 cm (2.62–3.28 ft) tall, it’s compact enough for stealth grows but powerful enough to impress connoisseurs.

How to grow Do-Si-Dos Cookies for maximum flavor and yield

Get the most out of your Do-Si-Dos Cookies with this expert-backed grow plan.

Quick start and strong roots

Begin with germination in a moist, dark environment at 22–25 °C (71.6–77 °F).

• Use jiffy pellets or starter cubes for minimal root disturbance
• Transplant when the taproot is ~1 cm (0.4 in) long
• Keep humidity at 60–70% during seedling stage
• For faster rooting, try B.A.C Organic The Final Solution

Controlled vegetative growth

Keep veg short and focused—this strain doesn’t stretch excessively.

• Use 18/6 light cycle with strong LED or HPS
• Grow in 11–20 L (2.9–5.3 gal) pots depending on space
• Train with LST to open up canopy and boost light penetration
• Feed lightly—avoid nitrogen overload with Top Max BioBizz

Flowering with flavor in mind

Switch to 12/12 to trigger flowering and maximize resin production.

• Lower humidity to 40–50% to prevent mold
• Support heavy colas with soft ties or trellis netting
• Boost bud density with B’CUZZ BLOSSOM BUILDER LIQUID
• Flush 7–10 days before harvest for smoother smoke

Harvest, dry, and cure like a pro

Timing is key—harvest when trichomes turn milky to amber.

• Cut branches and hang upside down in a dark, cool room
• Dry at 18–22 °C (64.4–71.6 °F) and 50–60% RH for 7–10 days
• Trim and cure in glass jars, burping daily for 2–4 weeks
• Store in airtight containers away from light and heat

Personal Experience of Pevgrow’s CEO (Alan)

I grew Do-Si-Dos Cookies in my 1.20 m x 1.20 m (3.94 ft x 3.94 ft) tent with a 600W LED. I used the SCROG method and topped once early in veg. The plant stayed compact, filled the screen perfectly, and produced massive, resin-dripping colas. Flowering took exactly 52 days. The smell was rich—sweet earth with a minty kick. After curing for three weeks, the high was exactly what I wanted: deeply relaxing, slightly euphoric, perfect after a long day. I’d grow it again in a heartbeat. Pair it with Complejo TNT for even better resin production.
