Substrate for dry starting HC
What substrate and fertilizers do I use?
I only have the inert Tahitian Moon Sand right now, but I read somewhere I can use some sort of soil that is gardening, but I can't find it so here I am asking.
I don't want to buy another bag of Eco-Complete or stuff like that because I'm dry starting in a very very small tank and the extra stuff would be wasted. So if there is a safe gardening soil I want to get that to dry start the HC and plant some tomatoes and strawberries.
And for ferts, I have most Seachem liquid minus the Excel and Trace.
