Don't use vermiculite, it's a waste of money. Just get some good potting soil at a grow shop and some powder fert that comes in a box with alot of bacteria to it. Read the contents and make sure you get a fert that has bacillus and mychorrizae fungi in it. Use one level cup for every 4 liters of soil. Transplant into the bigger pots, don't use the smaller ones because you'll have to transplant later and that shouldn't be necessary.
