Know before you buy
Yes, it is formulated as a complete 'water-only' medium. Because it is heavily amended with compost, worm castings, and organic nutrients, you should not need to add liquid fertilizers or extra amendments for most standard growth cycles.
Sterilization kills the beneficial bacteria and fungi that plants need to thrive. By keeping the soil unsterilized, BuildASoil preserves a living ecosystem that helps break down nutrients and makes them more readily available to your plant's roots.
While this is a nutrient-dense soil, it is quite 'hot' for very young seedlings or delicate clones. It is best suited for established plants or larger containers where the root system can handle the high concentration of organic amendments.
It is a high-quality blend of peat moss, compost, and biochar, resulting in a light, airy texture that promotes excellent drainage and root aeration. This structure is designed to prevent compaction, which is essential for long-term growth.
Living soils are generally self-buffering, meaning the microbial life and organic matter help maintain a stable pH environment for your plants. While you don't need to be as precise as you would with synthetic fertilizers, using clean, dechlorinated water is always recommended to protect the soil's biology.
Absolutely. It is specifically designed for potting and performs exceptionally well in indoor containers. Just ensure your pots have adequate drainage to support the healthy microbial activity within the mix.
