Looking at a new Growing Media tired of soil want to try something new

I us some 247 tranplanters so I have seen their stuff. I think the diameter of one of the tall bags fits. It might be the 3 gallon. My thinking is to use one of these, turn the side down a bit so it is not so tall yet provides a little more volume. I did this with their 2-gallon transplanters in my Another Clone SOG and TBD
