About Cosmic Collision

Cosmic Collision is a sturdy, resin-heavy hybrid bred from Stellar Kush x Nova Haze that suits growers willing to manage humidity. It produces citrus-berry aromas and medium-high yields when grown with good airflow and considered feeding, and performs well under organic approaches.

Grow Difficulty:

Growing Cosmic Collision in my wet Welsh valley climate requires careful mould prevention and strict canopy control. It is moderately challenging but manageable with preventative pruning and good airflow.

Flowering Time:

Flowering completes in around eight to ten weeks under stable conditions. Buds fatten nicely in the final fortnight with regular feeding.

Yield:

Yields are medium to high when plants receive steady nutrients and humidity control. Outdoor crops can be generous if harvested before persistent autumn damp sets in.

Height:

Plants develop a medium-tall frame with robust side branching and compact cola formation. The structure suits both screen-of-green and low-stress training.

Environment:

Indoors it responds well to SCROG and controlled environments in Gloucestershire. Outdoors in my garden in Gloucestershire it prefers a sheltered, south-facing site to avoid prolonged wet.

Climate:

Growing Cosmic Collision in Gloucestershire means contending with a wet Welsh valley climate that can push humidity levels high. Protective measures like raised beds, extra ventilation and careful timing are essential in Gloucestershire to avoid rot.

Common question Posted by Urbanseedbank Answered
Q
How did your last outdoor crop fare in Gloucestershire?
A
Verified answer
The last outdoor run did well until a late autumn wet spell accelerated bud rot on a couple of plants, so I recommend earlier harvest dates.

Q
What was your biggest challenge this season?
A
Verified answer
Controlling humidity during late flower in my wet valley microclimate was the biggest issue; I added dehumidifiers and raised beds to help.

Q
Which pruning technique worked best?
A
Verified answer
Selective defoliation and early topping produced the most even canopy and reduced internal shading without stressing plants.

Q
Do you recommend any specific organic amendments?
A
Verified answer
Worm castings, bone meal during early bloom and a kelp foliar in late veg gave noticeable vigour and improved terpene expression.

Q
Would you grow Cosmic Collision again?
