Bye AVT - Hello GWK
Rinse / Repeat - Reuse NO
It's labeled a 'soiless' medium, containing the following:
"It contains sphagnum peat moss, coco coir, aged softwood bark, perlite, worm castings, bat guano, feather meal, bone meal, blood meal, sulfate of potash, kelp meal, and volcanic ash."
Peat coco and perlite are the primary components. I amended with new castings, additional perlite and 1/3 new medium + a mild precharge.
Don't fix it if it's not broken... Well where's the fun in that!?! Lol
