Had my plants in a couple of weeks now and have run out of the plant-gro i got free with the nutrafin co2 system, so need to buy some but havent got a clue which one is best, ive heard that many do not have enough iron, is this true?
Me, too, although I haven't used it in a month and the plants seem to be doing just as well as beforemrnewbie said:i use kent freshwater plant , i dosw 2 ml every other day and my plants have gone wild
In my experience the most important factor for growth has been the level of light.
