haha don't get too discouraged. sometimes threads can take a while to get going, let alone have people reply to them. anyways, i have to say that your plants look very good, and i think its cool that u are experimenting with diff types of soil. i haven't heard good things about MG products for weed, but your plant seems to be doing great in it- so keep us posted. definitely don't kill them, if you are only growing a few at a time they are very low maintenance. if you need any help, just ask. i will be checking in. good luck!
