those are the only 4 product that i use, the ones you mentioned. also i forgot to mention was , iam using 3- 3gallon pots and 1 4 gallon pot, and someone was asking about what could you use to make the water drain better. well i picked up some window screen and cut to fit the bottom of my plant pots , and after i finished watering my plants lastnight, water was the only thing that drained, no soil, just the water. and that also will keep the roots from growing out of the holes as well.
