You can be extremely successful using Fox Farm products. I believe Roots Organic makes competitive products as well. Use the Happy Frog for starting and the Ocean Forest for larger pots or for putting plants in the ground. The michoriza (sp?) will attach to the roots and will provide phenominal growth when compared with other brands of soil. Especially for the first soil the plant touches it is essential to have one like Happy Frog that attaches proper nutrients to the root system. Fox Farms also makes a seed starter soil that I have seen but never felt the need to try since the Happy Frog works incredibly well for starting seeds or clones. They also make a supplement that you can add to an equal amount of your own soil so you have twice the volume of treated soil as if it were all Fox Farms. Anyway good growing.
