BuildASoil's Heaviest amended soil recipe was designed with the Water Only grower in mind. Based on Logan Labs soil testing they designed a soil with more everything. This 3.0 Recipe is our richest soil and is still be balanced enough for most all plants. The goal was a compost based soil without any dirty ingredients that would last longer and push harder. If you are used to Super Soil this will perform as you would expect. This potting soil mix has been the favorite for customers that want everything already in the soil when they open the bag. Compared to our other potting soil recipes this is their most loaded up potting mix. Excellent for flowering and full term growth.


They Pre "Cook" This recipe until it ramps up and back down in temperature but still want to encourage growers to make 100% sure before they plant.

Due to the nature of mixing multiple composts and ingredients together it is possible that this potting soil will heat up once combined into larger volumes and watered in. Please be sure to double check soil temperatures before planting into. (Especially likely when combining over 10 Cubic Foot Soil bags into a new container)


THEY DO NOT sterilize any of their compost or potting soils during the manufacturing process and as a result it will contain a plethora of life. This could be beneficial mites, fungus and microbes as well as, from time to time, unwanted fungus gnats. While they do their best to keep anything unwanted to a minimum we cannot guarantee it. They always recommend purchasing beneficial insects to combat this possibility and/or learning best practices to avoid population explosion.
