About Siz
Siz is a practical hybrid bred for reliability and resin production, with genetics that favour compact structure and steady yields. It performs well indoors and outdoors but requires careful attention to airflow and harvest timing in regions like Leeds where rainy autumn conditions can affect finishing.
Siz is a balanced hybrid that combines vigour with manageable stretch. It suits growers who want a reliable, versatile plant.
Siz typically tests between 18% and 22% THC, giving a clear cerebral lift with gentle body ease. The potency is consistent enough for regular use without being overpowering.
Siz carries low CBD levels around 0.5% to 1%, so CBD effects are subtle. It is chosen mostly for its THC-driven profile.
Siz descends from NORTHERN LIGHTS x SKUNK which gives it stable traits and good resin production. That lineage explains the earthy aroma and dependable structure.
Siz is commonly available as feminised seed to ensure predictable flowering and no male plants. Feminised seed simplifies choices for hobby growers and small breeders.
Siz is best described as an intermediate grow that rewards attention to airflow and disease prevention. In Leeds the rainy autumn harvest season increases mould risk so canopy management and timely harvest are essential.
Siz flowers in roughly eight to nine weeks under good conditions. Expect a compact finishing window that suits planned harvests.
Indoor yields are medium to high when trained and fed properly. Outdoor plants can deliver respectable crops if harvested before prolonged autumn rain.
Plants reach a medium height with a sturdy central cola and productive side branches. They perform well under both SCROG and low-stress training.
Indoors Siz responds well to Sea of Green and screen of green setups and stays manageable. Outdoors in Leeds it benefits from a sheltered site to reduce wind and rain damage.
Growing Siz in Leeds requires planning for the region's rainy autumn harvest season and cooler temperatures. Choose a late-summer transplant, maximise sun exposure and be ready to dry-harvest early if heavy rain threatens.
The high is balanced between upbeat mental clarity and comforting physical ease. Users report focused creativity without heavy sedation.
Flavours lean earthy with citrus top notes and a pine finish. The smoke is clean and slightly spicy on the exhale.
Frequently Asked Questions
Common questions about this strain, covering growth, effects, and suitability for UK conditions.
Yes, Siz is well suited to cool climate cannabis strains lists because it tolerates lower temperatures and finishes relatively quickly, but you should manage mould risk in wet periods.
Aim to finish outdoor flowering before the heaviest autumn rains arrive by transplanting early and using protective covers or polytunnels if wet weather is forecast.
Use a phosphorus- and potassium-forward feeding schedule in the mid to late flowering phase while cutting back nitrogen gradually to promote bud density.
Maintain good airflow through pruning and spacing, avoid overwatering, and consider early harvests or protected growing to reduce exposure to damp conditions.
Yes, Siz's medium height and predictable stretch make it a good fit for small tents with SCROG or low-stress training to control canopy.
Harvest when trichomes show a mix of cloudy and some amber for balance; delay slightly for deeper body effects but watch weather if growing outdoors.
Routine integrated pest management is usually enough, but monitor for spider mite and aphid pressure, especially in sheltered outdoor spots.
Dry slowly at 10-20°C and 50-60% humidity for 7-10 days, then cure in jars for at least two weeks for improved flavour and smoothness.
Training is not essential but horizontal training and topping increase yields and help manage height in limited spaces.
Beginner growers with attention to mould prevention and basic nutrient knowledge can succeed, but it is best for those ready to monitor weather and canopy conditions.
