Instead of buying both fox farm, which is the company name, the soil name is ocean forest, and happy frog, just get the ocean forest and a box of fox farm's fruit and flower box of fertilizer. you can get the frog soil if you want, but usually what I tell people to do is get the ocean forest and a box of fruit and flower fertilizer in the yellow box, and mix one full cup of fert into a 5 gallon bucket of ocean forest. Pour about two gallons of soil into the bucket and pour one half the fert cup in, then mix and wear a glove or plastic bag over your hand to prevent slivers. Then pour in the rest of the soil followed by the remaining cup of fert and mix that in. It's okay to use pot with a dish at the bottom, but you probably should dump any water that collects in it. You want the soil to dry out some before watering again. When you say you planted in plain soil, does that mean plain potting soil or dirt from outside?
