I-95 Strain — Effects, Genetics, Grow Guide & Where to Buy
I-95 earned its place in the modern cannabis canon for a reason — and the appeal is easy to explain. It is a indica-dominant (71% indica / 29% sativa) testing at roughly 20% THC, with a flowering window of 8-10 weeks under a 12/12 photoperiod. Below we walk through what to expect from the high, how the plant grows in a tent or outdoor garden, the parental genetics behind the cultivar, and how to get I-95 seeds delivered anywhere in the US.

I-95 Effects & Experience
I-95 is best known for relaxed, sleepy, happy. The effects come on within the first 10 minutes and settle into a stable plateau that lasts 90 minutes to two hours at typical doses. Growers and users consistently note that the high stays true to its profile rather than drifting — what you feel in the first 20 minutes is what you have for the next 90.
Growing I-95
Growing I-95 fits cooler climates and high-altitude growers, where the compact structure resists wind and the short flower beats early frost. I-95 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: feed cal-mag from week 2 onward at 2-3 mL per gallon — most reverse-osmosis and soft tap water setups need it; 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 training timing — top at the 4th node, not earlier and not later, for the best canopy distribution.
I-95 Lineage & Genetics
This cultivar comes from the Royal King Genetics breeding program — an in-house line developed for fast finishing and heavy yields under indoor conditions. Phenotype consistency is the result of multiple generations of selection rather than commercial seed-run breeding.

I-95 FAQ
Is I-95 indica or sativa?+
I-95 is a indica-dominant with a 71% indica / 29% sativa split. The effects lean toward physical relaxation and a calm, settled headspace.
How long does I-95 take to flower?+
I-95 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 I-95?+
I-95 tests at approximately 20% 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 I-95 good for beginner growers?+
I-95 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.
