I-95Strain, 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-95Effects & 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.

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.
