As fort384 told you before, you have to read a lot before you even try, if you fail to do so, you are going to waste a lot of money in plants, lights, substrate, and other stuff. Plants are living things just like fish. they won't grow if they are not under the right conditions, and you will probably get desperate and frustrated when they start to die. Right now the stickies n this forum are your best friends.
Things you should read about:
* Lighting
- types
- Color temperature (K)
- wattage and plant needs
* Substrates
- Gravel
- sand
- combined
- etc
* Nutrients (fertilizers)
- root tabs
- (there are others)
* abbreviations (people used them quite often)
- IMO = In My Opinion
- T5 HO = T5 (type of light) High output
Edit: for some reason I did not see the 2nd page so you may or may not have read about any of this stuff if you haven't you should start right now, if you have I'm sorry I didn't mean to repeat all of this stuff
