Hello all! There is a culinary mushroom grow operation by me that gives out bags of the spent substrate (red oak chips and soybean hulls) for free after the fruiting is done. Would you guys use the substrate for container hot peppers?

I'm growing hot peppers for the first time, so I am curious what you all think. What proportion of SMS would you use? Otherwise, I'm going with a coco coir and perlite mix. Some resources on the internet that are not hot pepper growing specific imply that up to 30% of the containers could be filled with the spent substrate.

Very curious to hear your thoughts on this.
