no prob!
yea i ordered 6 1/2gal mason jars with rye berries allready in them.. cost about as much to ship them here! and each one was only half way full .. maybe 1/4 lb?
bags are just a better deal, and easier to work with...
once the substrate is colonized it forms to the jar and only real way to break it up is beating it on a tire or roll of duct tape (something with give) and i didnt really like brusiing it up that much...
tip.. if you DO make your own its easy to make a self healing injector point... put a dot of silicone on the filter patch smaller than a dime, and inject through that...
good luck!
