Meet FrostRailz, an enthusiast who jumped into indoor cannabis growing with an adventurous spirit and a meticulous setup. He picked Granddaddy Purple feminized seeds from WeedSeedsExpress, renowned for their heavy colas, knockout potency, and legendary genetics. His cultivation space became an indoor haven, powered by the robust Optic 6 Gen4 LED grow lights, pumping out 570 watts of precise, spectrum-rich illumination, ideal for both vegetative and flowering stages.

The soil was custom-mixed, a thoughtful blend of organic soil and coco coir, enhanced with Dr. Earth’s nutrient range, steering his plants toward maximum vigor. FrostRailz adopted the Sea of Green (SoG) method, along with strategic defoliation to maximize yields. After a carefully monitored journey spanning 79 days from germination to harvest, his dedication bore fruit: dense, frosty nuggets bursting with creamy, gassy, and minty terpenes.

Granddaddy Purple Grow Diary Week by Week

Week 1 & 2: Vegetation

FrostRailz watched like an expectant father, anxiously noting the first signs of life. The seedlings showed vigorous growth, pushing up towards the LEDs set at just the right distance. Conditions hovered around a cozy 29 °C, with a stable humidity of 68%. Early development was rapid and healthy, each seed cracking open confidently, a promising start to the adventure.

Week 3 & 4: Transition

Week three saw a major milestone, transplanting to the final 19-liter pots. Despite the stress of relocation, the plants showed zero signs of transplant shock, a testament to FrostRailz’s careful hand and meticulous preparation. Nutrient introduction began gently with Dr. Earth’s Pure Gold Fertilizer, laying the groundwork for robust vegetative growth. The flip to 12/12 lighting was executed a tad earlier than planned, adding an extra bit of stretch to the flowering stage.

Week 5 & 6: Flowering

As expected, early flipping before calyx development meant an extended stretch phase, but the ladies held strong under intense LED exposure. A rich feeding of Premium Natural Kelp Meal bolstered their resilience. FrostRailz tackled heavy defoliation with confidence, clearing out any clutter and ensuring optimal airflow. By week six, two distinct phenotypes emerged, teasing him with potential purple hues.

Week 7 & 8: Bud Development

Bud growth shifted gears dramatically in weeks seven and eight, aided by Life All-Purpose Fertilizer. FrostRailz observed massive colas forming, some clearly set on turning purple, others remaining green but equally dense and sticky. His hands-on approach, coupled with nutrient precision, fueled an explosive flowering response.

Week 9 & 10: Late Flowering

Final flowering weeks saw colas swelling significantly, dripping with trichomes and emanating powerful aromas. FrostRailz employed Flower Girl Bud & Bloom Booster, maximizing terpene expression and bud density. The anticipation peaked as he debated whether the purple phenotypes would fully express their legendary colors, a genetic mystery soon to be solved.

Week 11: Harvest

Harvest was met with satisfaction, buds so hefty and frosty, they resembled crystalline, dense rocks. Although no dramatic purple fully emerged, the exceptional bag appeal and aromas, creamy, gassy, minty, validated his careful cultivation. A whole-plant hang dry followed, optimizing moisture content and locking in flavor.
