My thread will have what happens.
I did something different, having bought bags of soil previously. I ordered a yard of soil for the yard 
and baked it in the oven (No way I am letting outdoor critters getting in, been through that.). Then mixed in some recycled bag grow media (think it was more peat based) that was baked and washed also. Yes, no microorganisms but you pick your battles. The water beaded up on first waterings but seems fine now and the plants are growing. I am used to a looser media (mainly coco) and it took a little to get used to watering and not having runoff right away. But at $25 a yard for soil and some perlite and peat I will give it a go. Will not be as fast growing as coco but that stuff aint cheap up here also.
