Those substrates don't have any nutritional value to the plants, so either they'll just not grow or die. If you put a lot of root tabs in there then it may work out.
That's completely false. Plants take in nutrients through the leaves, that's why people dose fertilizer into the water.
Root tabs and fertile substrate are beneficial though
I've got plants growing a few inches per week in my 75 with regular sand substrate (plus CO2 and fertilizer)

should i put a Co2 system on my tank????
If you've got too much light then it helps a lot to keep algae under control. Even if you don't, it speeds up growth a lot.
A 20 lb tank, regulator, solenoid, needle valve, etc will probably cost around $200-$300

and the WPG and Kelvin rating I dont even know I have no clue how to figure it out??? The light fixtures I have are 48" Glo double T5 HO with 54w Powerglo and 54w Marineglo bulbs in each fixture.
Actinic bulbs (blue, like the marineglo) produce less PAR (measure of light used for photosynthesis) than regular daylight bulbs (white). Personally I think they look a bit ridiculous on a FW tank in most cases.
The glo fixtures are decent. It doesn't have individual reflectors around each bulb, I don't think (might be wrong). You'll probably need to suspend them several inches above the tank to get adequate lighting towards the front and back.
