Kannabia Sativa Dream - Pheno Hunting

greenkeepers 🌱 Sativa Dream – Week 2: Selection Begins This week marked a major step forward for our Sativa Dream line. Out of a total of 208 seedlings, we selected 33 individuals, including 2 tagged as control plants. The selection process involved close examination of each seedling, supported by macro photography on day 5 and day 8 after germination. Although day 5 felt slightly early and day 8 a bit late, the traits we were aiming for appeared clear and consistent in both sessions. This gave us confidence to make accurate selections and build a strong foundation for this cultivar's development. All selected plants were transplanted into 1L pots and received a feeding solution based on Base & Grow from Advanced Nutrients Cultivator Series and Voodoo Juice Plus, prepared with RO water, adjusted to pH 5.9 and EC 1.4. By the end of the week, we observed the first roots emerging at the bottom of the pots, a sign that our crop steering strategy with dry-backs is working well. Environmental conditions have been favorable, with temperatures holding around 28°C as the summer heat fades away in Leipzig. We maintained humidity at 68% RH using the Pure Fogger by The Pure Factory, while Provent fans ensured strong, consistent airflow. At 28°C and 68% RH, our VPD is approximately 1.0 kPa, which supports strong root growth and early vegetative vigor in this energetic sativa hybrid.

greenkeepers Week 3 – Sativa Dream – Root Rush, Final Cut & Ready for the Flip ☀️ From the original 130 plants, 18 Sativa Dream 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. After transplanting into 7 L pots, Sativa Dream quickly filled the fresh substrate with healthy white roots, reaching the bottom within days. This cultivar continues to show the fastest vertical growth among the four, with thinner leaves and a high tolerance for the intensity of the The Pure Factory LED Expert 720 W panels 💡. EC was increased to 2.0 using Cultivator Series base and grow formulas, with Voodoo Juice to boost root mass. Foliar feeds kept leaf health at optimal levels. This week, we also introduced beneficial insects — Amblyseius cucumeris and Amblyseius californicus — as a preventive measure against thrips and other potential pests. The flip to flower in Week 4 is mainly for space control 🌸 — keeping Sativa Dream compact ensures each plant has enough light and space to thrive without overcrowding, making canopy management easier during the stretch.

greenkeepers Sativa Dream started flowering this week with an early flip to stay on top of stretch and maintain uniform canopies across the room. Plants are adapting smoothly, and stretch has begun. Feeding has now shifted from Advanced Nutrients Cultivator Series Powder Line – Base + Grow to Base + Bloom, supported by Voodoo Juice Plus Tablets for root vigor, Big Bud for structural support, Bud Factor X for resin stimulation later on, Sensizym for improved nutrient availability, and Bud Candy for flavor and energy. Foliar sprays with algae extracts and Tasty Terpenes OG Organics were applied to keep leaves resilient and reduce stress during this critical stage. A first round of defoliation removed a small number of fan leaves, improving light penetration and airflow across the canopy. Humidity was reduced to 63% RH, stabilized by the Pure Factory Pure Fogger and Industrial Dehumidifier. Conditions have stayed in the sweet spot, giving Sativa Dream the best environment for the stretch. Across the 18 phenotypes, Sativa Dream is showing energetic, upright growth. The overall development is relatively even, with tight internodes and a consistent structure across the group.

greenkeepers 🌱 Week 5 – Sativa Dream ☁️⚡ Sativa Dream is living up to her name – growing fast, stretching tall, and already showing strong energy. Because some plants stretched faster than others, we reorganized by size and type so that every Sativa Dream can catch maximum light and keep the canopy balanced. We took two clones from each plant, using our go-to combo: Elite 91 Clone Solution plus Eazy Plug CT104C. It’s been giving us excellent results, and the new clones are looking strong from the start. Foliar sprays continued this week with Tasty Terpenes and B-52, giving that lush green shine and keeping the plants happy. Sativa Dream is shaping up into a powerful, vigorous cultivar – tall, leafy, and full of potential for the flowering stretch ahead.

greenkeepers Week 6 – 3rd week of flowering Disclaimer from the author: this update begins with a short introduction from Matías, followed by the plant report. This week we’ve been a bit behind with pictures, as we are working on multiple projects at the same time. Still, we’re excited to share an important milestone: since September we are finally officially employed within the club. For us, this marks the step from hobby to craft, both in content creation and in the cultivation of this wonderful plant. Bit by bit, we are building something sustainable – a project that not only supports itself but also creates opportunities for others. It’s about laying the foundation for more jobs, more projects, and more recognition around cannabis, something that for too long had to remain hidden. Just a couple of years ago, I could never have imagined this becoming reality, and yet here we are. For that, I feel nothing but gratitude – to our club members, our partners, our friends, our collaborators and the authorities. Without your trust and support, none of this would be possible. It’s crazy to think that only a small number of people in Europe can say this today, considering how incipient the legal industry still is. Even more so as an immigrant in this country, I feel deeply honored to be part of this process. And while we celebrate these steps, it’s also important to stay strong and not let anyone take away what has already been achieved. Every step forward may feel small in the moment, but when you look back, the progress is huge. For decades this plant was criminalized, given a bad reputation, and forced into the shadows. To us it is medicine, ritual, and part of daily life – something far less harmful than many substances that remain legal today. Thanks to legalization, cannabis and its active compounds can now also be studied in greater depth, helping us better understand its potential, how it interacts with our organism, and allowing us to leave behind decades of stigma. Compared to how long this plant has been persecuted, the improvements we’ve seen in just the last few decades are nothing short of extraordinary. Now, turning to the plants: the first signs of flowering are here, and the differences in stretch between the cultivars are becoming even more noticeable. Our clones have shown great vigor – more than 95% not only survived but also developed explosive root growth. This confirms once again that the Elite 91 + Bigger Eazy Plugs combo was a fantastic choice. Thanks to Mario for that tip – we won’t be going back to anything else. Just from their structure, we can already start imagining a pre-selection of mothers. Even at three weeks from germination, it’s clear which ones naturally reach the size we want, and which ones might need a bit more time to catch up. That being said, nothing is written in stone – sometimes a plant that looks less promising early on ends up surprising us later. Some may only start to show their true potential after a few extra days or even weeks, and in the end, the real verdict only comes once the buds are cured. Defoliation has been done gradually, allowing more light penetration without stressing the plants too much at once. At the same time, we couldn’t resist experimenting with under-canopy lights, which means we didn’t need to strip the lower branches too heavily – just enough to keep good airflow. We’re curious to see if this small change boosts production by a noticeable percentage. This was also the final week of foliar feeding, and the moment we introduced new micronutrients into the root solution: B-52, Big Bud, Bud Candy, Sensizym, Bud Factor X, and Voodoo Juice+. And of course, we couldn’t finish without mentioning aromas: Pink Gelato is now releasing a sweet candy-like fragrance. Simply walking past the plants you’re greeted with the scent of an artisanal candy shop. It immediately takes me back to La Dulcería in Cerro Alegre, Valparaíso – a place full of colorful handmade candies. If you ever find yourself wandering through Valparaíso, follow the painted ants on the sidewalks of the hill, and you’ll find it. Each cultivar is already starting to show its personality: Zoap Rose impresses with its powerful stretch, reaching for the light with unstoppable energy. Apple Fritter leans toward a sharper, more citrus-forward aroma, a refreshing contrast to the candy sweetness of Pink Gelato. Meanwhile, Sativa Dream shows off its elegant, slender leaves and airy structure, already promising that classic sativa vibe. Together, they make the room a diverse and exciting place to walk into every day. Finally, I want to thank each and every one of you who takes the time to read these entries. Your support, words, and reflections mean a lot. You are warmly invited to leave a comment or share your own thoughts – it’s always a pleasure to hear back from this community. If you made it until here, thank you for taking the time to read – we build this together! We won’t disappoint on next week’s report, where we’ll share more personalized cultivar photos and details. Let’s celebrate this milestone together!
