#5. Organic Plant Magic Potting Soil with Earthworm Castings - Compression

Have you ever thought about how large and unnecessary bags of potting soil are? You surely have since they all come in large sizes and waste too much of your space. That is why the Organic Plant Magic Potting Soil with Earthworm Castings is small in size, but significant in terms of efficiency.

This bag of the super soil is compressed to preserve space, but it also expands up to 7 times its size once you add water to the growing mix.

The formula, combined with the nutrients required to make this type of potting soil a super soil, works incredibly fast and delivers water and the right amount of nutrients to your plants twice the time it takes for a regular potting soil.

Also, if you're growing a large number of cannabis plants, you can mix this super soil with your regular garden soil and still get the same results. Otherwise, you can use it independently, and it'll do the trick.

However, some customers claim that this product is a bit overpriced since they can get a similar amount of coconut fiber mix for a lower price. Still, they work differently, and some people might find a better use for this cannabis soil than the coconut mix.

#6. Super Soil Organic Concentrate - Simplicity

Are you ready to mix your super soil? Here's your main ingredient, the Super Soil Organic Concentrate.

The great thing about it is that after you add the potting mix, there's no more hassle. This concentrate is filled and enriched with all the major nutrients needed for healthy development, ranging from organic earthworm castings to coconut water powder.

The price may concern you at first, but once you consider how much potting soil you'll get in the end, it's a reasonable sum.

However, be thoughtful and read the instructions since the concentrate is quite potent, and if you use a lot without adding enough potting soil, there is a risk of injuring and burning your plants. So, try to look at the right ratio between the number of cannabis plants you're growing and the mix you're adding.

All in all, you won't regret using this concentrate for your potting mix.

Moreover, this blend can feed a single cannabis plant through its entire cycle in a 15-gallon pot, which is a massive deal with products like this.

Overall, it's a great product, just bear in mind that it might be too potent for seedlings, and you should use it once the plants have grown a little. Other than that, it's a perfect friend to your plants.

1. Potency

Of course, strength is an essential aspect of this product, probably the most important one. However, incredibly powerful soil mixes can quickly destroy your plants if you're not careful enough.

All the best mixing soils have instructions based on the potency of their nutrients in ratio to the number of cannabis plants you're growing. Also, pay attention to the size of your plants.

As we've seen, seedlings are not quite healthy to handle dominant soil concentrates, and therefore they should be taken care of carefully, and once they are larger, you can use the mix freely.

2. Nutrients

The most important thing to know with nutrients is never to overstep.

Even though they are crucial in maintaining healthy growth, all plants are different, especially cannabis depending on the climate and the area you're nurturing it in. 

So, pay attention to the list of nutrients that your mix has and compare that to the conditions where your plant is growing.

But, if you're looking for simplicity, coco fiber is a constant that will do amazing things for your plants.

3. Price

Many potting mixes can be quite expensive due to the number of added nutrients and the manufacturer.

However, if you're growing cannabis in more significant numbers, you should invest a bit more money since the premium brands are quite potent, and their design is targeted towards broad distribution.

However, if you're growing it for domestic purposes, you'll be quite satisfied with the mid-range ones, and you'll save quite a few bucks.
