Outdoor cultivation of CBD Auto 20:1 using a super soil mix.

Starting My CBD Auto 20:1 Grow – Outdoors & Budget-Friendly! Strain: CBD Auto 20:1 from 420 Fast Buds Collection Growing Method: Outdoors (Budget-Friendly Approach) Soil Mix: 1/3 Super Soil Mix + 2/3 Biobizz All Mix Today marks the beginning of an exciting new grow journey with CBD Auto 20:1 from the renowned 420 Fast Buds Collection. Known for their top-tier genetics and reliable performance, Fast Buds have consistently delivered quality strains with impressive resilience and potency. This time, I’m focusing on achieving a high-CBD harvest with minimal THC, perfect for making my own CBD oil. The plan is simple and budget-friendly: I’m keeping things outdoors, letting nature do its work while providing the best possible soil mix for optimal growth. To keep costs down while ensuring quality, I’ve crafted a soil blend using: 1/3 Super Soil Mix – Packed with nutrients, organic amendments, and beneficial microbes for enhanced root health and plant vitality. This should provide a rich environment for healthy growth right from the start. 2/3 Biobizz All Mix – One of the best organic potting soils available, known for its rich microbial life and pre-fertilized blend that supports vigorous growth through all stages. Biobizz All Mix offers excellent water retention and aeration, making it a go-to choice for both beginners and experienced growers. I’m starting the seed indoors on a sunny windowsill to give it a strong start before moving it outdoors once flowering begins. The entire cycle will be completed in a 3.5L pot, which should be sufficient for this hardy autoflowering strain. From what I’ve read, 420 Fast Buds’ CBD Auto 20:1 is resilient and quick to finish, with a life cycle of around 9–10 weeks from seed to harvest. That’s perfect for my outdoor setup, especially since the British summer can be unpredictable. I’m excited to see how this CBD-rich strain performs under natural light and my custom soil mix. Looking forward to sharing updates as the grow progresses and ultimately making my own CBD oil from the harvest! Let the journey begin! Day 4. Here we go – day four and the first little loop has emerged! I’m excited to share the beginning of this CBD Auto 20:1 grow, especially because this one will be quite unique. This project is all about minimalism, natural conditions, and realistic, budget-conscious cultivation. This Fast Buds strain caught my attention for its super-high CBD content (up to 20%) and very low THC – perfect for oil production. Their autoflower genetics have a strong reputation for reliability, resilience, and great cannabinoid profiles – exactly what I’m after. For soil, I’m using a mix of Biobizz All Mix – known for its excellent microbial life and structure – and my own organic super soil, pre-charged with beneficial amendments like worm castings, bat guano, rock phosphate, and biochar. No bottled nutrients. No feeding schedule. Just soil, sun, and water. The plant currently lives on a sunny windowsill, where it receives about 7 hours of direct sunlight daily (~1350 μmol/m²/s) from 07:00 to 14:00. After that, light levels drop significantly, but this setup is intentional – no supplemental lighting, no moving the pot to chase the sun. I want to observe and document how well an autoflower performs under strong, natural light with a limited daily light window. Later, once the plant enters the flowering stage and the weather improves, it will move outdoors to finish its life under the open sky. I’m aware this approach may slightly extend the flowering and maturation time – likely by 3–5 days compared to optimal full-day lighting – but that’s part of the fun. This is an experiment in effortless growing and real-world conditions. Let’s see what nature + good soil can do. Day 6 – The First Hydration: Pure, pH-Balanced, Oxygen-Rich The little warrior is now on Day 6, and it’s officially past the most delicate moment of its early life – germination. The cotyledons are fully open, and the first pair of true leaves is starting to stretch confidently. The seedling stands tall, and the stem shows healthy colour and early rigidity. Today I performed the first watering: 1L of clean, pH-balanced tap water. Oxygenated with an aquarium airstone and air pump. Water temperature: 18°C Application method: Gentle circle around the base to encourage outward root spread No added nutrients, no boosters – just carefully treated water and rich soil doing their job. Although I don’t measure the temperature or humidity near the windowsill, the environment has proven supportive so far. This plant receives direct sunlight from 07:00 to roughly 14:00, reaching a peak of ~1350 μmol/m²/s PPFD during midday hours. After that, the sun shifts and the light fades. No artificial light supplements are used – this is a real test of how far quality sunlight, soil, and water can take an autoflower. Why oxygen matters in water: Roots don’t just drink – they breathe. Oxygen availability in the root zone is crucial for: Root cell respiration. Microbial life in living soil (especially in super soil and Biobizz All Mix blends) Nutrient conversion and uptake. By using oxygen-enriched water, I aim to promote: Stronger root development. Healthier microbial interaction. Less anaerobic stress in the root zone. While cooler water holds more dissolved oxygen, 18°C is a sweet spot – oxygen is retained well, and roots avoid the shock caused by colder temperatures. Looking forward to observing how this approach influences early growth, structure, and resilience. It’s all about low-intervention, real-world growing – and the journey has just begun!
