are root tabs necessary?

So I'm trying to grow some amazon sword and jungle val in nothing but inert fish gravel. I know they are root feeders, and my dirted tank grows them faster than I can manage some times.

I was going to put a root tab a few inches under the sub but then I thought for a moment... this gravel is your typical gravel. It's not tight packed like sand, so putting a tab under 2 inches of gravel... wouldn't it just work it's way out into the water column? Or better yet, couldn't I just dose the water column and said dose would find it's way (with time) under the 2 inches of gravel and nourish the roots anyway? Thoughts? Experiences?

Root tabs are not necessary for sword plants. But, the plants may grow noticeably faster with root tabs. If you want to use the "best" set-up, dose the water and use root tabs, too. Just don't overdo the water fertilizing unless you also do large weekly water changes to keep the nutrient concentrations from getting too high.
