Do Si Dos Seeds: Genetics, Flowering Time & Grow Tips

Shopping for do si dos seeds usually starts with the name. Do Si Dos, also spelled Dosidos or Do-Si-Dos, is one of the most influential Cookies-family strains of the last decade, and it parented a long list of newer ones. The Do Si Dos feminized seeds we sell are Atlas Seed’s Dosidos, a faster finishing version of the original. This guide covers where the genetics come from, what Atlas changed, and how to grow it.

Do Si Dos Seeds: Genetics Behind the Cross

The original Do Si Dos came out of the Girl Scout Cookies line, from a cross of OGKB, a Girl Scout Cookies selection, with Face Off OG. It went on to parent strains such as Slurricane and Peanut Butter Breath.

The original takes its time to finish. Atlas Seed’s version is, in their words, a faster finishing rendition. They got there by outcrossing to their Cotton Candy line, which also gave the plant its open spacing between nodes. Atlas sells it as an F1 feminized photoperiod and classes it as semi-full term, the same quick photoperiod group as their Peanut Butter Breath.

Atlas points to one more effect of that cross. Because the two parent lines are so unlike each other, the seedlings show a lot of hybrid vigour.

What the plant looks like

Stocky and medium branched. The flowers are dense and round, from golf ball size down to what Atlas calls frosty popcorn, and the aroma is sugary sweet cookie. Atlas also notes that it trims easily, by hand or by machine, because the buds are round and carry little leaf.

Finish time

Atlas describes it as quick, but has not published an outdoor finish date for this version, so we do not give one here. Indoors you decide when it flowers by switching the lights to 12 hours on and 12 off.

Grower Tips

Use the vigour. Fast early growth means it fills a pot quickly, so pot up before it gets root bound, or start it in a large final pot.
Top it once and tie the branches out. A stocky plant rewards an even canopy with more top colas.
Thin the inner growth around the third week of flower. The open node spacing helps, but dense flowers still need air.
Stake or net the main branches by mid flower. Round, dense buds get heavy.

Choosing Between Indoor and Outdoor Grows

Indoors it stays stocky, which suits a standard tent. Outdoors, southern Ontario and the south coast of BC are the realistic regions; see the Ontario guide and the BC guide. In short-season provinces, start it indoors, or pick an autoflower.

Curing for Flavour

Much of this strain’s appeal is its sugary cookie aroma, so a patient cure pays off. Dry slowly in a controlled space before you jar it, and open the jars regularly in the first few weeks.
