I knew i was going to butt hurt soil lovers,
1. Ph is one of the biggest problems people have with soil, doesnt take much reading and researching to figure this one out.
2. Soil root mass is always smaller in soil than with hydro or coir, been growing for decades.
3. I fell out my chair on this one, its impossible to over water with coir/perlite 75/25 unless you dont have any drain holes.
4. Coir is sterile, there is no nutrients for microbes or organisms to grow unless you add soil or organic nutrients that contain pest.
5. I couldn't stop laughing, this is common knowledge.
6. See number 5
7. Coir is like a sponge, it is nothing but air and coir mass which is why it is so light compared to soil. Air freely moves within it.
8. Yes you can reuse soil but it builds up waste quicker than coir. One quick flush is all you need with coir.
