Why not try composting? A couple of weeks in a compost bin and your stuff will be unrecognizable and you'll have some nice soil additive for other gardening possibilities. I put roots, stems, left over leafage etc. in the bin and stir it up occasionally for excellent compost for outdoor plants.
Growing weed has made me a better vegetable gardener and no worries about the garbage man finding anything.
Just another option.

Chineseyes Reviewed by Chineseyes on . Root Mass Ok guys, so I just began flowering of my first ever crop and yesterday culled the males outta there. The question is, is there anything at all functional or useful about the root masses? There were two boys, grown hydroponically in 6" pots meaning 216" cubic inches of root mass per plant. That just seems like a lot of material to dispose of. Any info is appreciated. Thank s guys. http://i45.photobucket.com/albums/f72/Kame543/IMG_4342.jpg Rating: 5
