well would like to know if any one can list posible subsitutes to Al's 5-1-1 mix and the grity mix ingredients , to have more options to watch out for : ( here in puerto rico

such good concept as ( Al's 5-1-1 and the grity mix have not tried it but many users have read at other plant forums say its good ) look like the best option for container plants to show their best, but been having difficulty to find the ingredients :( ;

have been calling different places, plant nurserys , local hardware stores, inclusive at HD , they didnt know or heard of TURFACE or PINE BARKS FINEs , neither :(( .

am i the only one from PR trying to use this mix ? just asking in case someone in my area knows posible substitutes for them : ( , can anyone help ?

or do you have another option or way to make well and good aerated medium for plants????? thanks in advanced : )
