It's all yours if I can get it into Ziploc bags, some of this was pushing 4'. There's a lot of younger plants though, so no worries if I have to compost some of the oldest growth.
Refilling now. I've filled it halfway, stirred the substrate, drained again and now have added another bag of Eco Complete.
I'll trim anything off the stump while in the water. There's surely Bolbitis and Java fern I don't want in this one growing on it, but I'll wait until I can pull the paper towels to do so.
