I'm not sure if this post goes here, please move if so. But I'm thinking about buying some auto flowering seeds to grow and I'm wondering if the soil mix i have planed out is good enough Cow Manure 1/3 Worm Castings 1/3 coarse sand 1/3 and i only want to use the most basic soil mix. please send feedback
So you wanna grow organically? This soil mix would be too high in nitrogen - and lacking in other essential parts - IMO And if you plan on using chemical ferts then you can forget the manure and worm casting because the Synthetic chemical will kills all the microbes in your soil - which defeats the objective. Someone please correct me if I'm wrong. I like to use the lightest mix possible for growing all cannabis indoors - Coco + Perlite 50-50 mix. Coco holds water + nutrients Perlite (Processed sand) provides aeration. Its a very simply mix In nature, roots serve two primary purposes - sucking up water and nutrients + structure. Out in a field - if the soil was too light then a plant might fall over in heavy wind - in a grow room this is much less likely - which means we can have lighter + more airy soil, which promotes general plant health. Hope this helps!
