About Chem Sister

Chem Sister delivers a clear cerebral lift alongside gentle physical relaxation and a distinct citrus-diesel profile. It is a balanced hybrid bred from Chemdog x Sister that responds well to training and performs best when growers control humidity and protect late-season buds, especially in regions with a short outdoor growing season.

Grow Difficulty:

Under a short outdoor growing season, Chem Sister requires attentive timing and careful site selection. Growers should treat it as moderate difficulty and use early sowing or protected locations to avoid lost weeks.

Flowering Time:

Flowering usually completes in eight to ten weeks under stable conditions. Outdoors in cooler climates the finish can be delayed if light and temperatures drop.

Yield:

Yield is medium to high when fed correctly and when resin development is promoted. Expect dense colas that benefit from some selective trimming to improve airflow.

Height:

Plants reach a medium height with sturdy central stalks and good lateral branching. They respond positively to low-stress training and topping to keep canopy even.

Environment:

In Surrey, Chem Sister does well when given shelter from cold winds and steady humidity control. Outdoor growers in Surrey often use polytunnels or greenhouses to protect late-season buds from rain.

Climate:

Surrey's short outdoor growing season requires planned planting dates and use of microclimates to ensure ripening. Using polytunnels, greenhouses or early-flowering phenotypes will reduce the risk of autumn rains spoiling buds.

Common question Posted by Urbanseedbank Answered
Q
My buds feel damp late season, what now?
A
Verified answer
Prioritise airflow and remove any dense inner foliage; if rain is expected consider moving plants under cover to prevent bud rot.

Q
What training did you use to keep height down?
A
Verified answer
I topped at the fourth node and used LST to spread the canopy, which kept stretch manageable and improved light penetration.

Q
How often do you check trichomes for harvest?
A
Verified answer
I inspect trichomes every two to three days once week seven of flowering begins and look for mostly cloudy heads with some ambers for a balanced effect.

Q
Do you run any supplements in late flower?
A
Verified answer
I use a low-dose PK booster around week four of flowering and reduce additive use in the final two weeks to avoid excess salts.

Q
Any tips for drying in humid Surrey autumns?
A
Verified answer
Dry inside with controlled dehumidification or move freshly cut branches into a heated, ventilated polytunnel to maintain steady conditions and reduce mould risk.
