The pros and cons of using the time release soil verses the additives is an apples/oranges kind of thing.

You'll find the additives issues far more fixable than using that crummy soil. A lot of folks even like the MG additives but then you get into the heavy metals verses quality organic arguments and the discussion usually drops off into the deep end about then. It's a call you're going to have to make according to your own priorities.

Just stay the hell away from that god dang MG six month soil unless you want a good rump ramming.
leadmagnet Reviewed by leadmagnet on . Miracle Grow and Cannabis...Good or Not?? Hello everyone, first time grower here and Ive got a 1 plant that ive started out with and it seems to be doing very well. Its into its 2nd week of flowering now. 12/12 light cycle with 2- 120 watt 5000k, 1250 lumens CFL's I started out on the veggie cycle using Miracle Grow water soluable 18-18-21, deluted very well in water. I did experience just a little bit of burning on a few fan leaves on the edges due to me spraying the mixture directly on the leaves and then setting it out in full sun Rating: 5
