Recently, bianca heard a cool trick from her friend. You can give your babies an extra dose of carbon dioxide by spraying them with seltzer, or some other carbonated water. Very nice.
Another friend, long liberated from work and its addictive excrement money, recently suggested urine as a good source of nitrogen. Experience has told her that one cup of urine per gallon of water speeded the growth, and increased the strength of her plants. This was especially true during the fast growing period which occurs about two weeks after germination.
