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.

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

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.

Avoid Miracle-Gro Soil for Growing Weed!

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!

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 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.

The biggest problem with the standard 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.

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?

MiracleGro is probably the most famous plant food in the world. The fertilizer was first developed in the late 1940s by Horace Hagedorn and Otto Stern, who also came up with the distinctive packaging and name, which are still in use today. From here, it has become a household staple in the fertilizer market, beloved of horticulturalists around the world.

What Is MiracleGro?

If you don’t fancy the D.I.Y method, there are plenty of other options out there. Some of the best on the market are:

What Can You Use Instead of MiracleGro?

If you are looking to grow your own cannabis plants, it makes sense you want to give your babies every possible benefit. Just like parents with their children, your plants quickly become your pride and joy, which you want to see grow big and strong. As such, you may be tempted to use a little MiracleGro to lend a boost. After all, it’s bound to help. It’s in the name, right?

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.
