soil??

I just picked up some vermaculite, perlite, and soil (im pretty sure those are the names, if not and u think u know what im talking about, lmk). Im just not sure what percentage of each i should have in each pot. Would there be like better ways to mix it depending on the stage my plants are in?

depending on the soil.. like if it is heavy and clumpy or not.. i would add about 1/4 of either the vermiculate or perlite, and 3/4 of the soil.. i am sure you could also add some of the other, whichever one that you didn't use the 1/4 of, to the puts...
what vermiculate and perlite do for a soil mix is to air it out, and help the roots breath easier, and allow more oxygen to get to the roots... so, if your soil seems a lil heavy and clumpy like i said, go ahead and add some of the perlite or vermiculite... and if it seems super heavy, you can go up to 1/3 of them to the soil..
