Like Jina said. Itd be good to know your medium, but depending on what way you go... Soil: After taproot shows, Id start with a 16oz Solo cup filled with soil (FoxFarm Ocean Forest), covered with about 1/4" soil. If using (FFOF) do NOT use nutrients. After about 3 weeks the plant should be about 5 to 8 inches and probably ready for a new pot. Transplant to a 1 gal potter and begin nutrients. Start at 1/4 strength and go up from there. After another 30 to 40 days it should need a new pot. Heres where you need to think of the size of plant you are wanting. If you want a smaller plant go with a 3 gal pot, Larger plants need larger pots, so 5 to 7 gallons is plenty.

Hope this helps a little..!
