Can You Grow Cannabis with Miracle-Gro?

Miracle Gro Plant Food is Not Suited to Growing Marijuana!

Keep miracle-gro away from your cannabis!Many of us have grown up seeing Miracle-Gro being used in our homes, so we know that it works for ‘regular houseplants’. Cannabis is just a tough weed, so Miracle-Gro should be great for it, right?

Not really.

The biggest problem with the standard Miracle-Gro nutrient formula is that it’s one formula for the entirety of the plants life cycle. Even if Miracle-Gro is good one for one stage of your plants growth, it won’t be good for all of them. The ratio of nutrients your plants need changes drastically between seedling and full flower, and marijuana needs a nutrient system to accommodate for those changing nutrient needs.

Avoid Miracle-Gro Soil for Growing Weed! 

Do not use “Miracle-Gro” soil or any soil that has “extended release” nutrients for growing cannabis. These types of soil will continue to release nitrogen to your plant roots for up to 6 months. 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.

What's even worse than the standard Miracle-Gro nutrients is 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.

Standard Miracle Gro nutrients contain too much nitrogen and not enough of other nutrients for your cannabis flowering stage, and as a result of the time-released nutrients you will notice that your leaves in the flowering stage will get nutrient burn and your buds just won't grow as big as they could. Learn what you can do to make sure buds grow as big as possible!

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.

Never Use Miracle-Gro soil for growing cannabis - especially don't get any soils that have "extended release" nutrients!

There's nothing inherently wrong with Miracle-Gro nutrients, and if you're willing to learn about nutrients, you can use the various different formulas and get a cannabis plant to grow. For example if you're using regular soil, you could use the standard Miracle-Gro formula for vegetative, and their "bloom" version for the cannabis flowering stage. 

Yet there's so many nutrient systems that are specifically formulated to grow a plant like cannabis. Why not choose to get better cannabis nutrients that will almost always produce better results? Some options like Dyna-Gro are priced about the same as Miracle-Gro nutrients, but you will consistently get bigger yields and more flavorful buds.
