Avalon Effects & Experience
Reported effects center on relaxed, sleepy, happy. Avalon pulls toward physical relaxation and a quiet, observational headspace — a profile that holds up across phenotypes when the seeds are grown to their potential.
Growing Avalon
Growing Avalon fits cooler climates and high-altitude growers, where the compact structure resists wind and the short flower beats early frost. Avalon is photoperiod, which means you control when it flowers by switching from 18/6 (vegetative) to 12/12 (flowering). Most indoor growers veg for 4-6 weeks before the flip. Indoor yields land around 450-550 g/m² under quality LED, and outdoor plants given full sun and 5-7 gallon containers reliably produce 500-700 g/plant. Expected plant height is 120-180 cm, with intermediate cultivation difficulty. Practical tips that move the needle: apply low-stress training in week 2 of veg — bend the main stem horizontally and tie down to expose lower nodes; and top once at the 4th node to encourage 4-6 even main colas instead of one dominant cola. The most common challenge growers report is over-feeding nitrogen past week 1 of flower — switch to bloom nutrients within 7 days of seeing pistils.
Avalon Lineage & Genetics
Avalon is a Royal King Genetics in-house cross. The parental selection was chosen for compact stature and resin density, then stabilized over multiple generations to lock in phenotype expression. Seeds run true to the description on this page rather than spreading across a wide range of expressions.

Avalon is a indica-dominant with a 79% indica / 21% sativa split. The effects lean toward physical relaxation and a calm, settled headspace.
How long does Avalon take to flower?+
Avalon flowers in 8-10 weeks once you flip to 12/12 light cycle. Outdoor harvest typically lands in late September to mid-October across most US zones.
What is the THC content of Avalon?+
Avalon tests at approximately 19% THC when grown to its potential. Real-world numbers depend on grow conditions, harvest timing, and curing — well-grown phenotypes can land at the high end of that range, while poorly cured flower tests lower.
Is Avalon good for beginner growers?+
Avalon is rated intermediate difficulty. Photoperiod genetics give you control over plant size and harvest timing, which means a bit more responsibility for getting the schedule right. Most growers with one harvest behind them handle this strain without difficulty.
