About High School Sweetheart

High School Sweetheart offers a lively cerebral lift paired with a gentle body ease, bred from Sweet Skunk x School Girl to highlight sweet terpenes. The strain performs well for intermediate growers in both controlled indoor setups and sheltered outdoor spots within a mild southern growing climate.

Grow Difficulty:

Growing difficulty is intermediate and rewards growers who use training techniques to control stretch. In a mild southern growing climate you should plan for moderate training and pay attention to moisture management.

Flowering Time:

Flowering indoors typically completes in eight to ten weeks. Outdoors the plants are ready around early October in comparable climates.

Yield:

Yield potential is medium to high with good canopy management and feeding. Outdoors in a mild southern climate plants can reach their full yield potential when given shelter from persistent rain.

Height:

Plants develop a medium-tall, somewhat lanky sativa structure with good lateral branching. Expect heights between 1.2 and 2.5 metres outdoors depending on pruning and support.

Environment:

Indoors it responds well to SCROG and light defoliation to control stretch in Edinburgh. Outdoors in Edinburgh it flowers reliably where summers are mild and sites are protected from excessive damp.

Climate:

Growing High School Sweetheart in Edinburgh benefits from the city's mild southern growing climate which gives steady temperatures and long light periods. Keep plants sheltered from prolonged damp and ensure good airflow to reduce mould risk.

Common question Posted by Urbanseedbank Answered
Q
How many plants per m² for SCROG?
A
Verified answer
One to two plants per m² works well; aim for a single main canopy to maximise light use and bud quality.
Common question Posted by Urbanseedbank Answered
Q
I had bud rot last season, what now?
A
Verified answer
Improve airflow, lower humidity in late flower and remove inner foliage to speed drying of the colas.
Common question Posted by Urbanseedbank Answered
Q
Should I top or fim this strain?
A
Verified answer
Both work, but topping early and training will produce a bushier plant and better lateral bud development.

Q
Any advice on nutrient strength?
A
Verified answer
Start at half manufacturer strength for young plants and increase to full strength through veg, reducing nitrogen as flowering progresses.
