Miracle-Gro Slow Release Soil is Not Suited to Growing Marijuana!

Can You Grow Cannabis with Miracle-Gro Soil? | Grow Weed Easy (1)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 thestandard Miracle-Gro nutrient formula is that it’s one formula for the entirety of the plant’s life cycle. Even if the standard Miracle-Gro plant food is decent for the first stage of your plant’s growth, it won’t be good for the budding/flowering phase. The ratio of nutrients your plants need changes drastically between seedling and full flower. Marijuana grows best with a nutrient system that accommodates their changing nutrient needs.

Avoid Miracle-Gro Soil for Growing Weed!

Do not use “Miracle-Gro” soil oranysoil 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 burnyour cannabis plants in the flowering/budding stage,reducingyour overall yields. I have seen growers successively grow cannabis in Miracle Gro, but many of them struggled withnutrient problemsin the flowering stage (like the following) even though plants were healthy throughout the vegetative stage.

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 workokayin 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 cannabisfloweringstage, 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 burnand 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 oranysoil 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.

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, youcoulduse the standard Miracle-Groformula for vegetative, and their “bloom” version for the cannabis flowering stage.

Yet there are so many nutrient systems that are specifically formulatedto grow a plant like cannabis. Why not choose togetbetter cannabis nutrientsthat will almost always produce better results? Some options likeDyna-Groare priced about the same as Miracle-Gro nutrients, but you will consistently get bigger yields andmore flavorful buds.
