you are over thinking it, the types of bugs and microbes that are essential to an organic soil are just that, essential.I have never grown anything in my life..so I have no evidence..nor do I know anyone who grows. Its just from what I read in some other forums from different people. Most explained that it was 'good' bugs..not predators. Some of them were bad. Either way..i really didn't know that its normal to have bugs in indoor growing with soil bought from a store. I was going to use 30% perlite as well. I actually only got the idea to grow weed indoors this march when I opted not to do a container garden (vegetables), on my balcony because of fear of ants coming in! lol (they crawl on the outside of the building walls for some reason) I understood if by my own errors, I would allow bugs to appear..like by overwatering, stagnant water, humidity..but the idea that they are part of the soil and its normal..i just didn't like that thought. Its the fact of how fast some of them were lol..I wouldn't be able to contain that without a 'real' setup.
yup, that stuff is good stuff, I just wonder if the aluminosilicates is ever bioavalible to the plant, like azomitePearlite degrades into fine white sand, which may explain why bugs don't like it. Personally, I'm getting better results than ever using a specific type of kitty litter. @RM3 told me about calcined clay & it rocks! I like it so much, I mixed 100 lbs into my raised garden today. Heavier than pearlite & lighter than sand. It's perfect for soil.
