About Hi C

Hi C is a sativa-dominant hybrid that combines Clementine and Haze genetics to produce a clear, uplifting high paired with citrus and tropical flavours. It suits growers who can manage a moderate level of care, particularly in cooler coastal and temperate regions where airflow and shelter are crucial for a successful outdoor finish.

Grow Difficulty:

Under a cool Scottish outdoor climate Hi C requires careful attention to airflow and disease management. The cultivar is moderately demanding but rewards growers who manage humidity and give wind protection.

Flowering Time:

Flowering normally completes in nine to ten weeks under stable indoor conditions. Outdoor growers should plan for a late-season finish and monitor trichome development closely.

Yield:

Yield is medium compared with modern high-yielding hybrids and responds well to canopy management. Indoor yields increase with SCROG or SOG training while outdoor crops benefit from supplementary support.

Height:

Plants develop a medium-tall, sativa-leaning structure with long branches and spaced nodes. Training and pruning keep height manageable and improve bud site development.

Environment:

Indoors Hi C takes well to low-stress training and controlled light schedules in Warwickshire. Outdoors it prefers sheltered, well-drained sites and will perform best in Warwickshire gardens with extra sun exposure.

Climate:

Growing Hi C in Warwickshire demands planning because the cool Scottish outdoor climate increases the risk of damp and late-season mould. Choose a south-facing, sheltered site and prepare for an earlier harvest window to avoid autumn rain in Warwickshire.

Common question Posted by Urbanseedbank Answered
Q
My Hi C is stretching too much, what do I do?
A
Verified answer
Implement low-stress training and add a trellis to support branches, and reduce stretch by tightening light schedules or increasing light intensity indoors.
Common question Posted by Urbanseedbank Answered
Q
Should I defoliate heavily to prevent mould?
A
Verified answer
Defoliate selectively to improve airflow around bud sites but avoid over-pruning which can shock plants and slow ripening in cool conditions.
Common question Posted by Urbanseedbank Answered
Q
When did you last feed before flowering?
A
Verified answer
I gave a final nitrogen-rich feed two weeks before switching to 12/12 and then moved to a bloom formula with higher phosphorus once buds formed.

Q
How do you protect outdoor plants from wind in Warwickshire?
A
Verified answer
Use windbreaks, plant in sheltered spots, and secure stems with soft ties to prevent wind damage and reduce stress on developing buds.
Common question Posted by Urbanseedbank Answered
Q
Do you start seeds outdoors or indoors in a cool climate?
A
Verified answer
I start seeds indoors to get a head start and transplant after hardening off to give young plants the best chance against late spring chills.
