The Cross
To buy Sierra Madre Mexican seeds, know SnowHigh Seeds crossed Guerrero Circa 78 with Michoacan straight landrace. Goal was simple: preserve 1970s Mexican sativas from Pacific sierras. No gimmicks. Breeder chased narrow-leaf structure and spear buds adapted to rugged coasts. They hit the mark on paper. Real-world runs confirm the heirloom vibe holds.
Parent Contributions
Guerrero Circa 78
Brings the sativa skeleton. Tall nodes, fast stretch, resin on pre-flowers. Medium bud sites stack under sierras stress. Purple potential in cold snaps, confirmed in related lines.
Michoacan Landrace
Pure Pacific Coast fire. Narrow leaflets, multi-branching, spear colas. Aroma leans earthy pine with fruit flash. Vigor for long seasons. Stabilizes the F1 for heirloom traits.
The Phenotypes
Three main types show. Greens dominate: tall, stretchy, hazy bag appeal. Purple-leaners bleed late, shorter internodes, denser cores. Runners: vigorous but loose, cut them early. Keepers balance spear density with side branching. Variation tracks parent landraces. No uniform pack here. That's the point of old genetics.
Finding the Keeper
Seedling stage: taproots thick, first leaves narrow. Veg: even node spacing, no hermaphrodite flags. Stretch hits hard, train early. Flower: resin beads pre-bloom, spears fatten mid-way. Aroma builds citrus-earth. Mature: calyxes stack tight, trichs milky. Hunt purple if you chase color. Yield favors structure over bulk. Test smoke for clean sativa lift, no couch drag.
In the Garden
Run outdoors if you can. Loves sun, heat, some wind. Indoors, top early, LST mandatory. Flower time unknown, plan 12 to 14 weeks. Medium feeder, watch nitrogen stretch. Stable under sierras mimic: 75 to 85 degrees day. Yields solid for landrace revival. No miracles.
The Experience
Clear-headed rush, cerebral edge. Uplift without jitters. Long tail, suits day use. Flavor: pine, citrus, faint spice. Potency unknown, but 1970s heirlooms rarely nuke. Funny thing: tastes like Mexico smells after rain. Solid workhorse high.
