About Ultra Bomb Cookie

Ultra Bomb Cookie is an indica-dominant hybrid bred for dense, resinous buds and manageable height. It offers a sweet cookie aroma with citrus and diesel notes and produces strong relaxing effects driven by a THC-forward profile. The plant suits small indoor setups and protected outdoor sites, but in Hampshire growers must manage humidity carefully to avoid mould. With an eight-to-nine-week flowering period and medium-high yields, this variety rewards attentive feeding and good airflow.

Common question Posted by Urbanseedbank Answered
Q
My buds showed white powdery spots, what now?
A
Verified answer
Remove affected areas and increase ventilation immediately; treat with a suitable fungicide if necessary and monitor humidity closely.
Common question Posted by Urbanseedbank Answered
Q
Should I top this strain or leave a main cola?
A
Verified answer
Topping once early promotes a bushier plant and multiple colas, which suits small spaces more than a single main cola.
Common question Posted by Urbanseedbank Answered
Q
How much should I feed during late flowering?
A
Verified answer
Reduce nutrients slightly in the last two weeks and avoid excessive nitrogen; focus on potassium and phosphorus earlier in flowering.
Common question Posted by Urbanseedbank Answered

Is flushing necessary before harvest?
A
Verified answer
A short flush of plain water in the final week can improve taste, though opinions vary; try a seven-day flush and compare results.
