Rocks Vs. Anything Else

[meggofishy]

I just bought two plants the other day and I am now wondering if I have the right subdrate. I just have plain old aquarium gravel on the bottom, will the plants still grow? should I get some sand, or soil? should I be getting those fertilizing disks?
 
thanks, i'm really new to the planted aquarium thing, any help would be appreciated.

Yes the roots will still grow. Root tabs (discs) cant hurt, fertilisers are always a good idea when it comes to planted aquariums.
What plants have you bought?

a cambomba and a corkscrew vallisneria. these two just to begin with, i haven't found any good stores that sell HC, or java fern but I am hoping to find a place soon. my oto loves to munch on the corkscrew and the other fish have totally ignored the combomba. and what about co2 diffusers, should I look into getting one if I want to have more plants?

These plants imo will definately need a liquid trace fertilizer minimum. CO2 is a whole different ball game really. Check the link at the bottom titled Pressurized co2 equipment flow and fert.
Co2 is normally only considered if you want a very heavily planted aquarium, high light, or if you want to grow high tech plants OR if you just want a challenge! CO2 can be very rewarding.
Like i said, check my link and think about if this is the route you would like to take
