There's no room. Trust me I want to do dry ferts. I have more control over what my plants need and get that way. But my wife has pretty much told me no. So I have to go the other route. So I just need to know which is a BETTER product...
oh the joys of women!
I would suggest buying the dry ferts, as well as a big bouquet of flowers to distract her while you hide the ferts up high in a closet somewhere. lol!
Also, flourite is inert. so some root tabs would probably be beneficial.
