Growing is so prevalent in my area I'll take bags of stem/leaf to the dump no issues. Half the time I'll see fan leaves on the ground beside the big bins that the previous guy had accidentally spilled -no word of exaggeration! They even have a spot to dump your old soil they mulch it and resell it. Guys'll pull up throw out a bunch of 5gal shaped rootballs w trunks in place and no one even bats an eye. One day it'll be like that everywhere -it's green waste FFS it shouldn't be an issue to dispose of !
Again that depends right for some its a problem living in suburbia where you got people watching every move you make .
sure there is a lot of compost stations , Again you look funny dumping out 30 - 60 - 500 3 gallon pots in the middle of winter , or even going to store that time of year to purchase 20 bags of pro mix BX lol just saying
its not a problem for lots also who has the space to just dump it anywhere and walk away years ago living in a small town it was still nail biting getting rid of 210 3 gallon pots of soil yes Dumped them in garbage bags then down some side road in the middle of no where but you know ,
There is always some fucking car showing up :)
when growing illegally no matter what be cautious real cautious.
Because when your not that is when people get caught
I have thrown stems in totes and sealed them out back and yes they smell like weed when you walk out back there
But yeah fire pit late at night burn little at a time making biochar or what ever its a win win .
But if your growing illegally play it smart
