There are some basic, key ingredients in Opus Grows: You have your peat moss and coir fiber, which are your base materials, and then the perlite and pumice — they’re your porous, drainage materials.
As far as active ingredients go, we have our organic compost, which is combined with natural amendments, and biochar (like our Bio-Tope®). Biochar is the ingredient that really sets the Opus Grows potting soil line apart from the rest. The number of microbes and organisms living in Opus Grows is very high, so when you combine that with the all-natural amendments and fertilizers, the microbes have a good food source and can produce a lot of nutrients that your plants need.
Opus Grows is a really good container mix for pretty much any type of plants. It has the nitrogen, potassium, and phosphorus that every plant needs to grow. It also provides excellent drainage, but at the same time, retains vital moisture. So, your plants’ roots won’t rot, but they’ll get enough water to survive hotter days without constant watering.
