Let my system cool down as I finished harvesting my first round (autos) from this soil, which follows the Build-A-Soil method, but I've sources much of my own materials, having them in-stock, but never using them with my previous grows, other than to start the soil, which was all tossed to the garden after one round each. So, this is my first truly recycled soil. I wish I had a bit more, for deeper roots, but overall, it's alright. Thanks for tuning in & as always: Happy, Healthy and Prosperous Growing ๐๐๐ค๐ค๐๐
