About Supernova

Supernova delivers high THC, robust growth and a citrus-pine flavour profile across a resilient hybrid lineage; it performs best in a sheltered greenhouse or well-drained outdoor plots and rewards careful humidity management with large, resin-coated buds.

Grow Difficulty:

Growing Supernova is intermediate and it requires active mould prevention in a damp coastal climate. Attention to airflow, pruning and spacing will reduce disease risk.

Flowering Time:

Flowering indoors normally completes in eight to ten weeks. Outdoors in the UK it tends to finish by late September to October.

Yield:

Yields are generous when humidity is controlled and nutrient delivery is steady. In a protected greenhouse or outdoors in Lincolnshire plants routinely reward growers with substantial harvests.

Height:

Plants develop a medium to tall frame with long internodes and a strong central cola. Side branches respond well to topping and low-stress training to maximise bud sites.

Environment:

A greenhouse gives the best compromise for protecting plants from coastal moisture while capturing sunlight in Lincolnshire. Outdoor plants in Lincolnshire can do well but need shelter and close monitoring during damp spells.

Climate:

In Lincolnshire growers must plan for the damp coastal climate by prioritising ventilation and drainage. A well-sealed, ventilated greenhouse or raised beds with rapid drainage reduce the risk of rot and support even ripening.

Q
How often should I prune Supernova in a greenhouse?
A
Verified answer
Prune lightly every one to two weeks to maintain airflow and remove shaded growth that invites mould.
Common question Posted by Urbanseedbank Answered
Q
What light schedule works best indoors for flowering?
A
Verified answer
Switch to 12/12 for flowering and keep temperatures between 20–26°C with a slight night drop to promote resin production.
Common question Posted by Urbanseedbank Answered
Q
Is foliar feeding recommended in damp climates?
A
Verified answer
Avoid foliar feeding during late flowering in damp climates to reduce mould risk; use soil or reservoir feeds instead.
