Antarctic This grow started on October 20, and today is December 26, which puts the plants into Week 9 of the overall cycle. The last defoliation and pruning was done around December 16. After that, I made a conscious decision to stop cutting and stressing the plants. Earlier in veg I definitely over-stressed them — too much training, too many interventions. In hindsight, that slowed things down instead of helping. From this point on, the goal was to let the plants recover, grow freely, and build momentum in order to reach the flowering stage as smoothly and quickly as possible. Lesson learned for future grows: less stress fewer unnecessary cuts more patience Sometimes the hardest part is not touching the plants at all, especially when your hands are itching to train and optimize everything. Week 9 is about recovery, structure, and preparation for flower. Next week marks the start of flowering.

Antarctic During this week, the main focus is aggressive canopy control using the net. I will be heavily weaving the plants into the screen, keeping everything as horizontal as possible. The goal is to prevent vertical stretch for as long as possible. I do not plan to let the plants stretch upwards freely during the early and mid stretch phase. Only towards the very end of the stretch will I allow some vertical growth. Because the plants are different in size, the strategy is simple: everything will be adjusted to the smallest plants smaller plants will be encouraged to stretch and catch up larger plants will be held down and constantly trained to stay at the same level A second net has been installed to help with stretch control and canopy management. Plants will also be woven into the second net as needed.

Antarctic During the stretch phase I was away from home for about a week. My girlfriend was only topping up the water in the reservoirs while I was gone. When I got back, I noticed that in some buckets the EC/PPM dropped very low — around 100–200 ppm, which means the plants ate almost everything during the stretch. Now it’s week 3 of flowering. Today I did a full reservoir change, switched to flowering nutrients and performed a heavy defoliation and branch removal. I removed a lot of unnecessary branches and leaves to improve airflow and light penetration. Tomorrow I plan to defoliate a bit more to fully clean up the lower and inner parts of the plants after stretch. Despite being left alone for a week, the plants look strong and healthy, stretch was intense, and now I’m focusing on stabilizing conditions and pushing into proper flowering mode.

Antarctic Week 13 (Plant Week 13) = Flower Week 4 I started light defoliation and canopy management gradually. I also did LST / stretching control because the plants kept stretching longer than expected. I created new tie-down points (new holes) and kept bending branches down to manage height and shape. I expected stretching to stop around Week 12, but the plants continued stretching in Week 13 and Week 14 as well. Because I felt I had defoliated fairly hard, I reduced light intensity to ~60% to lower stress and let them recover. I was also fighting high humidity during this period.

Antarctic Week 14 (Plant Week 14) = Flower Week 5 Humidity management became more serious, so I installed a dehumidifier. I focused on keeping the tent dry and stable, so everything runs properly (less risk of mold). Defoliation continued gradually across Week 13 into Week 14: small cuts consistently over time instead of one heavy session. Today (end of Week 14) I did the final defoliation session. This is the last major trim; I’m not planning to remove more leaves going forward. Buds now have a stronger smell, and the resin is very sticky during handling. If you want it even tighter, here’s a one-paragraph version you can use as a caption: Caption version: “Flower Week 3–4: Started gradual defoliation and canopy control. Plants kept stretching longer than expected, so I added new tie-down points and continued LST. Reduced light to ~60% after heavier trimming to reduce stress. Humidity was high, so I installed a dehumidifier in Week 4 and focused on keeping the tent dry and stable. Today I finished the final defoliation; buds are now noticeably more aromatic and extremely sticky/resinous.”

Antarctic This week marks week 6 of flowering and week 15 overall. Plants are now fully established in bloom and entering a very active development phase. Over the last several days I introduced a phosphorus-focused feed (PK / FECA). The response became visible after about 5 days — buds have started to swell noticeably, and flower structure is becoming denser across the canopy. Bud formation is accelerating and stacking is clearly underway. Water uptake is high: plants are drinking approximately 2–3 liters per day, which indicates strong metabolism and healthy root activity. Leaves remain mostly healthy, with only minor tip burn on some plants, suggesting they are close to optimal nutrient uptake without major stress. Defoliation this week was very light and selective, only removing leaves that were clearly blocking light or airflow. Most of the productive canopy is now positioned above the second net, receiving strong and even light. Night temperatures briefly dropped to around 13°C, which is not ideal but did not cause visible damage. Daytime conditions remain stable, and overall plant vigor is unaffected. Aroma is beginning to develop more clearly — slightly sweet and berry-like notes are noticeable, especially when working inside the tent. Based on current development, the next 1–2 weeks should be the most explosive period for flower growth, with significant increases in size and density expected. Overall, plants look healthy, vigorous, and well on track.

Antarctic Status: Mid-Flower (Week 7 of Flowering) Water & Feeding: The girls are extremely thirsty, drinking between 1 to 3 liters of fresh water daily per bucket. Metabolism is at its peak. Nutrient Stats: Maintaining a stable pH of 5.8. The concentration (PPM) is hovering around 900–1000, occasionally spiking slightly higher as they feed. Boosters: Heavily utilizing PK boosters to ensure maximum bud density and weight. Climate Management: Temperatures during this week averaged around 28°C, with occasional peaks hitting 30°C. Humidity is strictly managed by a heavy-duty 50L dehumidifier to prevent any moisture issues. Grower’s Note: The buds are noticeably solidifying. The Church and Wonder Pie are stacking weight, and the frost is becoming intense.

Antarctic Status: Late Flower (Start of Week 8) Canopy Adjustment: To ensure an even light spread, I’ve raised the Wonder Pie by placing it on a container. Now, all tops are leveled for maximum photon absorption. The "Draft" Hack: To combat the late-flower heat, I’ve implemented a new ventilation strategy. By opening windows in both the grow room and the adjacent room, I’ve created a cross-ventilation effect (draft). Temperature Drop: Success! I managed to drop the peak temperatures from 30°C down to a perfect 24°C. This drop is crucial for preserving terpenes and increasing resin production as we head toward the finish line. Current Specs: pH 5.8, PPM 1000. Stability is the name of the game right now.
