The entries in this journal are derived from daily voice memos recorded throughout the grow. A large language model (LLM) assisted with transcription and editorial organization, while all observations, measurements, and cultivation decisions were documented during the grow itself.

Weekly Summary
Planet of the Grapes (POTG) entered its first full week in a 3-gallon fabric pot after transplanting. Establishment was uneventful, and the seedling quickly emerged as the most vigorous plant in the tent. Throughout the week, growth remained compact with steady leaf expansion, while the primary focus shifted toward refining the growing environment through several humidifier adjustments. By the end of the week, the environment had stabilized and the plant continued developing without signs of stress.

Day 7
Watering: 100 mL
POTG was transplanted into its permanent 3-gallon fabric pot. The FoxFarm Ocean Forest soil mixture was already at an optimal moisture level for a young seedling.
──────────
Day 8
Watering: 65 mL
No additional irrigation was required following transplant. Moisture remained available throughout the medium, allowing the seedling time to establish without unnecessary disturbance.
──────────
Day 9
Watering: None
A light 65 mL irrigation was applied as the upper portion of the medium began drying. The seedling continued establishing well in the new container with no concerns noted following transplant.
──────────
Day 10
Watering: 75 mL
The medium had dried sufficiently to justify another light watering, which was applied as a ring around the seedling rather than directly against the stem. The second set of true leaves had begun to emerge.
Most of the attention today centered on the humidifier after condensation developed on the tent ceiling. Adjusting the outlet resolved the ceiling condensation but redirected moisture onto the LED fixture, where water accumulated before dripping into one of the pots. The humidifier was repositioned so the mist traveled parallel to the floor.
A small number of fungus gnats were also observed for the first time.

Day 11
Watering: 200 mL
Height: 2.25 inches
The root zone had dried appropriately following the previous irrigation. The second set of true leaves expanded noticeably while maintaining a compact structure and healthy coloration.
The humidifier reservoir emptied overnight before being refilled the following morning. Despite the temporary reduction in humidity, no visible changes in growth or appearance were observed and the humidity within the tent never fell below an acceptable range.
──────────
Day 12
Watering: None
No irrigation was required today. Although the surface of the medium had begun drying, adequate moisture remained beneath the top layer.
──────────
Day 13
Watering: 300 mL
Height: 2.5 inches
Vertical growth remained largely unchanged, but leaf development continued steadily. The first pair of true leaves had reached approximately 2 in in length while the second pair had expanded to roughly half that size. The increase in canopy size was more apparent than any increase in height, indicating the plant had shifted its focus toward producing additional photosynthetic surface area.
