Can You Grow Cannabis with Miracle-Gro Soil or Nutrients?

Miracle Gro Plant Food is Not Suited to Growing Marijuana!

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?

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.

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.

Top two reasons why you should never grow Miracle-Gro marijuana if you don’t have to.

Hello again my fellow cultivators, I hope everyone’s day went as planned. Today I’m going to talk about soil again, more specifically bad soil.

When I allegedly grew cannabis in Texas I made a lot of mistakes and growing Miracle-Gro marijuana was one of the bigger ones. Today, I never use Miracle-Gro in any of my gardens, cannabis or otherwise and encourage everyone I talk to about soil, NOT to use it. Putting aside the fact that it’s a Monsanto product and that the fertilizer that’s used is petroleum based. It’s just not a good soil to grow marijuana in. I understand that some of the higher quality soil mixes won’t be available to some growers because you live in a prohibition state or a small town or both. In those situations Miracle-Gro may be the only thing available to you, and I’ll give you the best advice that I know of for growing with it. Before I do that I’m going to tell why I don’t grow Miracle-Gro marijuana.

I used Miracle-Gro once and one of the problems that I had was that I couldn’t add the nutrients, beneficial microbes and fungi that I wanted to without severely burning the plant. This has to do with the time release fertilizer pellets that are in it. I had no idea how much fertilizer was being released or how often, so I couldn’t calculate a safe amount of nutrients to add.

The other problem with Miracle-Gro marijuana is the taste. I’ve tried different strains that were grown with it and they all have a harsh chemical after taste that just ruins the flavor of the flower. I have two theories about why this happens. These are my unscientific observations and opinions, take it or leave it. Definitely do your own research if this is the mix you’re going to use, we all have google.

  • During the last 2 weeks of flowering, just before harvest, the grower will stop feeding the plant nutrients and will just give it water. We do this so we can flush the residual nutrients left in the soil or substrate out, so we can produce a great quality, natural tasting cannabis. The Miracle-Gro seems to get in the way of the flushing and it will feed that plant petroleum based fertilizer up to the day you harvest.
  • Another reason for this taste could be the fact that Miracle-Gro isn’t formulated for plants that are meant to be volatilized (tuned into a vapor) or burned like marijuana. It was formulated for flowering and fruiting plants.

Now if you have to use Miracle-Gro, don’t use it for seedlings or young clones. This soil is too hot for those delicate plant stages. While in veg and all the way to harvest, don’t give them anything but water. If your feeling adventurous you can give them beneficial microbes starting the second week of flowering, but keep an eye out for burn.

That’s it, that’s all the advice I can give about Miracle-Gro marijuana. I’m all for simplicity and automation as long as the quality doesn’t suffer.
