I'll answer this one.
But, since I'm in a good mood. I will save you a search.
First Off, you want live plants?
1) Buy Substrate
2) Buy a Real Light, I'm talking about anything over $150 with 4 light bulbs in there. Don't be cheap, buy the good stuff, otherwise if you cheap out, your going to do, dyam, should have bought the good stuff first.
3) Make sure you buy a light fixture that you can replace the bulbs, don't buy some no name brand that you will never find a bulb for the next year.
4) Buy a plant, and cut off the old roots and plant
5) CO2 and all those alsome chemicals, if create your tank right and you got the fish in there creating co2 and waste, you shouldn't need all that extra stuff. CO2 and all the chemicals is the difference between, organic orange and non-organic
I'm all down for an organic plant.
