I don’t care how its sourced it’s still compost. What do u think an organic soil mix is? That’s an organic soil mix in that grow not a entirely coir grow like u tried to claim , go bust out a brick of coir and nothing else and show me plants growing start to finish in it without compost or worm castings mixed in… I’ll wait
Last season greenhouse grow was in a 120 degree daily summer, never once had to stick a thermometer in my soil
