Avoid Miracle-Gro Soil for Growing Weed!
Miracle-Gro Slow Release Soil is Not Suited to Growing Marijuana!
What’s worse than the standard Miracle-Gro nutrients is the original Miracle-Gro soil. Standard Miracle-Gro soil has “time-released” nutrients which contain high levels of nitrogen. While this formula will work okay in the cannabis vegetative stage (the first stage of life), the nutrients will continue to be slowly released throughout the plant’s life including during the cannabis flowering stage, which is not good.
Important: Do not use “Miracle Gro” soil or any soil that has “extended release” nutrients. These types of soil will continue to release nitrogen to your plant roots for up to 6 months. This can burn your cannabis plants in the flowering/budding stage and reduce your overall yields.

This can cause deficiencies or burn your cannabis plants in the flowering/budding stage, reducing your overall yields. I have seen growers successively grow cannabis in Miracle Gro, but many of them struggled with nutrient problems in the flowering stage (like the following) even though plants were healthy throughout the vegetative stage.
MG potting mix is fine for growing. If you are used to it you will not like their MG moisture control soil. Water seems to run right off.
WARNING — I have twice lost seedlings because the emerging plant got trapped in the soil by a large chunk of wood in the potting mix.
I run the MG potting mix through a screen that filters out the larger chunks of wood in the soil. Also, twice in 2 years I have had some kind of vine-looking
thing growing in my pot along with the bean. Something that came in the soil and grew. Watch for that. I sent a note telling the MG people and they sent me a check for $10.24.
