Really have been enjoying reading about SQ FT gardening.
Have done some searches and I hate to ask but here it is.
I just found a local supplier of vermiculite, a garden supply, and they have it in medium in 4 cuft bags and course in 2 cuft bags marked "square foot garden".
I know coarse is recommended but the thing is the 2 cuft bag of coarse is 17 bucks and the 4 cuft bag of medium is 19 bucks. 2 more dollars for twice the amount except it is medium.
Is the medium acceptable? I see where some people use it.
I have a hard time justifying the coarse when I can get twice as much in medium grade for only 2 dollars more.
Thanks for your consideration.
