miracle grow seed starting good for marijuana

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!

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.

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.

Big Rootz, as its name suggests, is an indoor cannabis soil that will encourage root growth of your indoor marijuana. In other words, it will increase nutrient uptake and will encourage the overall plant’s vigor.

More and more people think that growing cannabis indoors is a good idea- thanks to the changing “atmosphere” regarding the legality of marijuana. But you cannot just put your marijuana seeds in whichever kind of soil and expect to get super-tasty, high-quality buds. Good cannabis means that you’ll have to find some nice soil for your plant, and we’re here to help you find the best soil for growing cannabis indoors.

It contains aged and composted bark, compost, perlite, cinders, and also organic grade fertilizer.

4. Big Rootz All Purpose

This is a rich mix, and it can be used in herb gardens, hanging baskets, and practically anywhere you need high-quality organic soil for indoor cannabis.

According to the Big Rootz (the manufacturer), their product is an award-winning blend that will provide all the essential nutrients to your growing kit. Its contents are rather straightforward- compost, peat, coir, and worm casting. The producer didn’t disclose the information about the pH value of their product, but in their words it is pH-adjusted.

This was a very concise and general guide for buying the best soil for indoor cannabis. Needless to say, the exact type of soil for indoor use you’d like to buy depends on numerous factors like, for instance:

The marijuana soils we’re going to mention here relates to the potting soil, which is often rich in nutrients and is especially beneficial for latter stages of growth, but it’s not that good for seedlings as it the potting soil can impede the initial growth. In other words, after the germination period ends, potting soils are used, and the best soils for weed mentioned in this list should be used after the germination period.

MG does work and works very well but I personally think Scott’s/ MG is a terrible company and do you really want to grow your buds in something that can also be used to make bombs?

But you could also just buy fresh MG Soil for every grow.

I personally use my own compost mixed with ph balanced peat moss, perlite, garden lime, and Roots Organics soil to supplement it. Also after I finish a grow I will then add my soil back into my compost pile for the next time I grow. I don’t use MG because I can’t ever get that salt buildup out of the soil and therefore can’t grow well because of it.

MG – some love it, some (who have probably never tried) hate it. I can´t buy it here so have no idea.

That is the major problem with chemical fertilizers, they leave so much salt buildup in the soil that any micro organisms that are in your soil can’t possibly survive.
