First question - when you say mulm - Do you mean plant trimmings from fast growing plants, etc buried beneath the substrate to provide decomposition for CO2 and bacteria in the Diana Walstad Natural Plant Tank way? Or do you mean something completely different?
Second question - AS (AquaSoil) and PS (PowerSand) - How are these different from SoilMaster Select?
Thank you in advance for patience with my questions.
I wish you healthy and happy plants! |
