I dont think thats the case so much anymore,i gotta believe as wide open as cali is on the weed front with as many massive scale grows ive seen from cali a mess of weed has to be comming from there.
However i do know where your comming from,ive thought about it often,more from a standpoint of helping my friends & family get away from buying weed,since ive been growing again after taking a 20 plus year break ive dedicated half of each harvest to give to friends & family in hopes they'd see the benifits of growing their own supply & it's working well.
Since then ive helped build 4 grow rooms for my friends & brother,supplied the clones to them & i mentor them to make sure all goes well,two of my friends have also set up grow rooms for their family members using my clones,were doing our best here in Michigan to get back to where we were at in 1970 where everybody grew their own weed.
Ive came way out of the closet since we passed the Medical
Marijuana bill here in Michigan,last week i was at home depot getting plumbing & electrical supplies for my brothers new grow room & the plumbing guy at home depot made a comment about the supply's we were getting being an odd assortment for a DIY project,i blew his mind when i told him it was for 2 grow rooms for raising
marijuana.
It just takes putting the paranoia to rest & letting people know your willing to teach them.
