Linear regression (with ANOVA) statistics describing the effects of the CGW:P ratio on the physical characteristics of the growth media.

BD = bulk density; WHC = water-holding capacity; TPS = total porosity; AP = aeration porosity; WHP = water-holding porosity.+The p-value indicates the probability of a significant relationship between the physical characteristics of the growth media and the CGW:P ratio. F test is significant at n.s.p>0.05; ***p**p*pp>0.05.
