I work in data, but I'm just as likely to be tinkering with music, building something with my hands, chasing down a great sandwich, or diving into whatever's caught my curiosity lately.

CURRENT GROW: PLANET OF THE GRAPES

Phase I: Germination & Seedling

Days 0–14
Day 0

Seeds placed in warm, damp paper towel between two plates for germination

Day 2

Taproot emerged — transplanted to potting soil in 4×2×2 grow tent. Light: 24hrs ON

Day 5

Plant breached soil surface. Switched to vegetative light schedule: 18/6

Day 11

Height: 7/8". Healthy turgor. Applied small amount of water to pot edges

Day 12

Health check: Leaves praying upward, bright lime green meristem, symmetrical structure. Height: 1"

Day 14

Height: 1 1/8". Watered

Phase II: Vegetative Growth

Day 15–Present
Day 22

Height: 1.5" | Width: 3"

Day 25

Height: 1.7" | Width: 4". Watered

Day 28

Height: 2.75" | Width: 4.75" — Hit height target for 23–30 day window ✓

Day 42

Height: 4.5" | Width: 6.5"

Day 54

Height: 6" — Grew 1.5" in 12 days. Now requiring daily watering due to increased metabolic demand

Phase III: Flowering

Upcoming

Will switch to 12/12 light schedule to induce flowering

Phase IV: Harvest

Upcoming

Dry, cure, and enjoy the fruits of patience

Fluorescent Light Bulb (Low heat, energy efficient)
3-Shelf Wire Unit
Light Clamp
Fan for Air Circulation
pH Tester
Potting Mix (NOT generic gardening soil)
Bloom Fertilizer

LESSONS LEARNED

Substrate matters — a lot.

V2.0 failed due to using generic gardening soil. Potting soil provides proper drainage, aeration, and nutrient availability. This is now a hard rule.

Watch the leaves — they tell you everything.

Leaves "praying" upward indicates good light saturation and health. Bright lime green at the apical meristem confirms active growth.

Water needs increase with size.

Early stages required watering every few days. At 6" tall, daily watering is now necessary to meet increased metabolic demand.

Document everything.

Detailed logs allow you to replicate successes, diagnose problems, and set growth targets for future attempts.
