soil recipe help

I am planning on starting an outdoor grow next spring and need a good soil recipe... i live in south texas where the summers can be hot(over 100 degreese F.) and is very humid.

I live in a releativly small town so some items may be hard to find. Some local stores i live near are Home Depot, Lowes, WalMart, and several small local gardening stores.

and i was wondering where u mix ur recipe in, and how long does it have to sit and be stirred before it is safe to put my plants into it??

thx.

over 100 degrees? i read somewhere that cannabis stops growing at 90 degrees. pros correct me if im wrong please.

Do you have to deal with this gumbo clay substance we call soil too? Hard as cement when dry and this sticky goo when wet?

im growing indoor notherlights outside in the south texas heat, they are doing fine...although if it was cooler it would be better, where in south texas are you at?
