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.
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.
When choosing the right fertilizer for your marijuana plant, do a little research online and find a more suitable one, such as the ones we mentioned above. Keep away from MiracleGro!
What do you think of using MiracleGro to fertilize cannabis? Are you one of the few who have used it successfully? Do you have a better fertilizer not mentioned here? We’d love to hear about it in the comments below.
Perhaps surprisingly, MiracleGro is not a marijuana farmer’s friend. It is a common mistake many rookies make as the fertilizer is so ubiquitous in the world of plant growing. You can utilize MiracleGro successfully, but it is challenging to get right, and you risk ruining your grow for benefits that are easily gained from using a better alternative.
MiracleGro works wonders for plants with simple grow-cycles. Marijuana is not one of these plants. Cannabis goes through several different stages, and each requires its own blend of nutrients. This is one of the reasons why growing marijuana is so fulfilling. It offers even the most experienced of horticulturists a new challenge.
Final Thoughts on Using MiracleGro When Growing Marijuana
MiracleGro has an extended-release of nutrients. This means it will continue to release nitrogen for up to six months, leading to deficiencies, or even burning your marijuana plant in the flowering stage, which would reduce your yield dramatically.
MiracleGro is used to help houseplants and gardens by providing additional nutrients that soil naturally loses over time. In doing so, MiracleGro boosts the growth rate of plants as it provides the material needed in the production of new cell structures.
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 Can You Use Instead of MiracleGro?
You can minimize the use of fertilizers in marijuana cultivation to a point by picking breeds with strong genetics and utilizing as perfect a growing environment as possible. Despite this, you will most likely need some fertilizer at some point, especially when you are just starting out.
A lot of first-time growers use MiracleGro when cultivating their first plants. Don’t! MiracleGro is not recommended for use when growing marijuana. We will explain why.
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.
