About Mac Stomper
Mac Stomper is a resilient indica-dominant hybrid bred for dense, trichome-rich buds and stable performance. It suits growers who can provide steady environmental control and pays dividends with generous yields and pronounced terpene profiles.
Mac Stomper is an indica-dominant hybrid with dense, resinous buds. It combines physical relaxation with a clear-headed lift.
THC typically measures between 22% and 26% on mature flowers. Potency can vary by phenotype and growing conditions.
CBD is low, generally under 1%, so therapeutic effects come mostly from THC and terpenes. Small CBD levels may soften the psychoactive edge for some users.
The lineage pairs MAC with Stomper to emphasise trichome production and compact bud formation. This cross yields stable, resin-rich plants suited to varied environments.
Seeds are offered as Feminised photoperiod to ensure female plants for flowering runs. Photoperiod control gives growers flexibility over vegetative time and final plant size.
Under a temperate southern England climate the strain is moderately challenging due to late-season stretch and mould risk. Good ventilation, selective pruning and steady nutrient schedules reduce issues and improve bud quality.
Flowering completes in around eight to ten weeks for most phenotypes. Outdoor growers should plan harvests to avoid autumn rains.
Yields are above average for a compact plant when trained correctly. Indoor setups commonly reach 400–550 g/m² while outdoor plants can exceed that in favourable sites.
Plants develop a strong central cola and numerous side branches, resulting in a medium to tall profile. Expect 80–150 cm indoors and slightly taller outdoors given space.
Indoors it responds well to SCROG and SOG methods that control canopy height and light penetration in Edinburgh. Outdoors it performs best in a sheltered, sunny spot with good airflow in Edinburgh.
Growing Mac Stomper in Edinburgh works well because the cultivar adapts to the temperate southern England climate with cool nights and mild summers. Drainage, airflow and late-season mould prevention are crucial in these conditions.
Initial effects are bright and cerebral, sharpening focus and creativity. Over time a steady, relaxing body sensation eases tension without heavy sedation.
Flavours fuse earthy diesel with bright citrus top notes. A subtle sweet and herbal finish lingers on the exhale.
Frequently Asked Questions
Common questions about this strain, covering growth, effects, and suitability for UK conditions.
Use 18/6 in veg and switch to 12/12 for flowering; maintain strong, even light coverage to encourage dense bud formation.
Provide moderate to high phosphorus and potassium during weeks 3 to 7 of flower and reduce nitrogen to promote resin and bud density.
It is doable but not ideal for absolute beginners due to mould risk; choose a sheltered site and monitor humidity closely.
Low-stress training and SCROG are effective to control stretch and maximise canopy uniformity for higher yields.
Improve airflow, space branches, remove dense lower growth and harvest before persistent autumn rains arrive.
Most available lines are Feminised photoperiod; autoflower variants may exist from some breeders but check the seed description.
Harvest when trichomes are mostly cloudy with some amber for a balance of THC and sedative effects.
Yes, controlled climate cannabis growing in a tent is well suited because it allows precise control of temperature and humidity.
Watch for aphids, spider mites and thrips; use regular inspections, sticky traps and biological controls to limit infestations.
Dry slowly, then cure in airtight jars with regular burping for several weeks to preserve flavour and potency.
