greenkeepers Kannabia Pheno Hunt 2025 – Zoap Rosé Hi there! We are Anbauvereinigung Greenkeepers Leipzig e.V., a Cannabis Social Club based in Leipzig, Germany. We’re proud to present our biggest pheno hunting project to date, in collaboration with Kannabia Seed Company, The Pure Factory, and Advanced Nutrients. With their generous support — providing seeds, nutrients, and equipment — we’re able to carry out a selection process of considerable scale and precision. This project includes four cultivars from Kannabia’s genetic catalog: • Apple Fritter • Pink Gelato • Zoap Rose • Sativa Dream We’ve started with 548 seeds. After careful observation and evaluation, only 72 plants — 18 per cultivar — will be taken into the flowering phase. Our goal is to identify standout phenotypes based on structure, vigor, resin production, and other key traits. We’re also testing an innovative internal selection method aimed at improving the accuracy and repeatability of phenotype selection. While the details are still under internal research, this system forms the backbone of our decision-making process. The plan is to test it, validate it, and — if successful — release it publicly. So if you're interested, please be patient and stay tuned. We’ll keep you posted 😉 ➡️ Follow this and other future projects on Instagram: @greenkeepersleipzig 📅 Week 1 – Germination Each seedling was assigned a position and ID for internal tracking. Tagging and documentation were completed during this first week. Seeds were placed directly into Eazy Plugs, pre-soaked with osmosis water adjusted to pH 5.6, with no nutrients added at this stage. After germination, the first watering was done using a light nutrient solution: Advanced Nutrients – Cultivator Series (Base & Grow) EC: 0.9 pH: 5.7 Out of 110 seeds, 105 germinated successfully, resulting in a germination rate of 95.5%. We observed that the 44W LED lights used during early germination may have been too weak — or placed too high — which led to some stretching. We’ve since moved the seedlings under stronger lights to avoid further elongation.

greenkeepers 🌸 Zoap Rosé – Week 2: Selection Begins Week 2 brought the first selection phase for Zoap Rosé. From 105 seedlings, we chose 30 standout individuals, including 2 control plants marked with red tags. Each plant was carefully evaluated with macro photos taken on day 5 and day 8 post-germination. The key traits showed up clearly and consistently, making the decision process smooth and backed by visual confirmation. After selection, the plants were transplanted into 1L pots and given a nutrient mix based on Base & Grow (Advanced Nutrients Cultivator Series) and Voodoo Juice Plus with RO water, adjusted to pH 5.9 and EC 1.4. Root tips started showing at the base of the pots by the end of the week, which aligns with our crop steering approach: encouraging dry-backs and active root searching. Weather conditions have been on our side — with cooler, post-summer temperatures keeping the room around 28°C. To maintain optimal humidity, we relied on the Pure Fogger (up to 4 L/h output) to hold 68% RH, and used Provent fans for consistent airflow. Under these conditions, VPD is around 1.0 kPa, ideal for rooting and early veg development — which Zoap Rosé seems to be responding to beautifully.

greenkeepers Week 3 – Zoap Rosé – Root Rush, Final Cut & Ready for the Flip 🌹 From the original 130 plants, 18 Zoap Rosé were selected for the main room — the best 16 looking ones plus 2 control plants. Another 48 plants were moved to a separate room to flower there as well, and the rest that didn’t make it into either room were removed so we can focus entirely on the top performers. Once transplanted into 7 L pots, Zoap Rosé quickly established new root growth, with fresh white roots reaching the bottom within days. Growth remains balanced and uniform across all selected phenotypes, with early trichome formation already visible on the newest leaves. The canopy benefits from The Pure Factory LED Expert 720 W panels 💡, which have provided consistent, even lighting since the start of the cycle. EC was raised to 2.0 using Cultivator Series base and grow formulas, with Voodoo Juice to further stimulate root health. Foliar feeding has kept leaves in optimal condition. This week, we also introduced beneficial insects — Amblyseius cucumeris and Amblyseius californicus — as a preventive measure against thrips and other potential pests. Flipping in Week 4 will ensure Zoap Rosé remains compact, with even light distribution and enough space for every plant as flowering begins.
