Eight amazing strains in a 4x4 / ORGANIC

SWITCH420 Because I’m short on time for this run (I’m moving to a new home in January), I flipped to flower after about four weeks of veg instead of my usual two months. The plan is to keep this cycle to roughly three months in total. I also do not top the plants this time, it would arm them to long ... So, I’m running two Mars Hydro LED FC4000 EVO fixtures, delivering a solid 640W in the tent with beautifully even light across the canopy. As always, I’m using my living super soil—now on its fifth cycle—and it just keeps getting better. Pure gold at this point. I also invested in a precise PAR meter this round, which makes managing modern LEDs so much simpler and more consistent. The soil is supported with dry, organic amendments, and I refresh the biology periodically with compost tea preparations. So far, everything looks incredibly healthy—vibrant growth, strong structure, and no issues to report. For plant training, I’m using a gentle low-stress approach that opens up the structure and maximizes light exposure without removing healthy leaves. It keeps photosynthesis efficient and helps the plants express their full potential.

SWITCH420 Just after flipping into flower, the stretch has already begun. In only a week, the growth has exploded and the canopy is almost completely filled. The organic soil—energized with oxygenated compost preparations—comes alive during this phase, and you can clearly see how much the plants respond when the whole environment is dialed in. Working with living soil is incredibly rewarding. You’re essentially becoming the caretaker of an entire microscopic ecosystem—billions of beneficial fungi and bacteria working together in harmony. It truly feels like you’re pouring love straight into the soil. Going organic is such a beautiful journey. 🌱 A small insight from my experience: supporting soil biology with diverse microbes and natural extracts can make a real difference. Gentle watering, mindful soil care, and letting the system regulate itself helps maintain that balance. When everything aligns, you often see the plants respond quickly—leaves lifting, colors brightening, and an overall boost in vitality. It’s a wonderful transformation to witness. And beyond the visual growth, there’s something special about fully organic cultivation: the flavors, aromas, and overall experience often feel elevated in a very natural, expressive way. Another huge benefit is sustainability—you can reuse the same soil run after run, improving it each cycle as the living ecosystem matures. I’m on my fifth run with this soil, and I can genuinely feel the difference.

SWITCH420 This week consists in adjusting the stretch / lamp distance to canopy / replacing fans, sensors, managing PPFD. The compost tea of last week absolutely blast the stretch. Flowers are coming... One of the Aladdin's Skunk already frost even on big fan leaves... That's impressive after being flipped in flo for a little bit more than a week.

SWITCH420 At the end of this week, I’ll defoliate and lollipop all the plants in order to focus on flowering. To see how they respond to the environment I’ve lollipop and defoliate the first lady in the right corner — the Sunset Martini from LIT. I’ll watch how she adapts, and if it’s too hard on her, I’ll take more time with the others. I prefer doing it gradually, so I don’t shock them too much. For this run, timing is extremely tight, and I want to optimize every action and avoid any mistakes. So with everything I do, every change, I’m adjusting gradually — and so far, it’s working like a charm! Stretch is continuing, some plants gain 10 cm in a night ! Everything is vivid & alive ! Update DAY 21 / end of week 3 : Defoliation is done. It wasn’t the easiest task since I couldn’t fully open the tent, and taking the plants out wasn’t an option because they’re all connected to the Blumat gravity watering system… but it’s done! Haha. About 24 hours before finishing the defoliation, I brewed an oxygenated compost tea to enrich the soil with natural microorganisms and fungi, giving the plants the support they need to get through this heavy fan-leaf removal. One thing I’ve learned over time: when I’m working on the plants at the back, I have to be really mindful of my movements. If I’m not careful, my arms or a clumsy gesture can easily damage fresh bud sites on the plants in front, since I have to reach over them to get to the ones behind. And once those new sites are crushed… well, there’s no bringing them back.

SWITCH420 So here we are, entering the full flowering phase. I always enjoy checking on the garden about 24 hours after a major defoliation, as it’s a significant shift for the plants and they often need a moment to recover. The purpose of this pruning step is simply to open up the canopy, improve light penetration, and help the plant direct more of its energy toward flower development. I usually perform this cleanup once the stretch phase is essentially complete—around the third week of flowering. Before doing so, I prepare an oxygenated compost tea to support the soil right after the stress event. Along with that, I refresh the substrate with natural, slow-release amendments that provide what the plant needs during bloom. In addition to classic worm castings, I like using marine-derived inputs rich in phosphorus and potassium, such as fish- and kelp-based products, as well as nutrient-dense algae like spirulina. At this stage, it’s also the final time I introduce certain beneficial microorganisms, including mycorrhizae and bacillus strains, to strengthen the root zone. I make one last addition of magnesium-rich supplements (I use Epsom Salt) to support photosynthesis and keep the foliage vibrant. Following the defoliation, the compost tea offers an immediate boost, helping the plant transition smoothly through the stress. The amendments then sustain it for the rest of the flowering cycle. From here on, I continue applying compost tea weekly, along with humic and fulvic acids and a bit of molasses to nourish the beneficial microbes and fungi that keep the soil ecosystem thriving. If everything has been handled properly up to this point, the rest of the cycle should feel almost like cruise control. Just a few routine checks, minimal adjustments, and you’re good to go.
