Soil for growing marijuana

Some of these micronutrients include calcium, iron, sulfur, zinc, boron, manganese, and copper, which you’ll find naturally in things like bat guano, worm castings, molasses, kelp, coffee grounds, and more.

Like many aspects of growing, there are a number of pros and cons to creating your own cannabis soil. The pros, however, far outweigh the cons, and we encourage every grower to try preparing their own soil at least once.
Your buds are only going to be as good as the plants that bear them. And the best way to grow big, healthy cannabis plants is to use homemade super soil rich in nitrogen, phosphorus, potassium, and other vital nutrients.

If you want to plant straight away, you can still use some of the ingredients listed above. You’ll just need to be more careful as you’ll be at risk of creating a really nutrient-rich (or “hot”) soil that can actually burn your plants. As a general rule of thumb to get you started, try using the following ratios of soil and other ingredients:
Once they do, they’ll create a rich topsoil for your plants, similar to what they’d have in nature. This super soil will be rich in nitrogen, phosphorus, and potassium, as well as all the other micronutrients we mentioned earlier.
• Preparing your own soil requires a larger initial investment than if you simply bought regular soil and a few nutrient solutions. Keep that in mind if you’re growing on a budget, but also remember that the results are definitely worth it.
Start by placing your soil in a big container; break it up with a graip to ensure it’s well-aerated. Once it’s nice and loose, you’ll want to get to work enriching your soil with more natural ingredients to create a rich growing medium for your cannabis plants.
In the pots you plan to grow in, combine:

– 4 parts starter soil
– 1 part worm castings
– 1 part coco coir
– 1 part perlite/vermiculite (for extra drainage)
– 2.5–5% guano
– 2.5% bone and/or blood meal

Soil for growing marijuana

For photoperiod plants, start them out in small seedling pots/cups with soil that has little to no nutrients. Replant after a few weeks. More mature plants will tolerate higher nutrient levels much better than seedlings.

If you’ve just started growing cannabis, it may be best to simply get ready-made soil from the grow store. The reason for this is that good-quality cannabis soil normally contains everything your plants need for healthy growth, in the optimal ratios. If you want, you can further improve your store-bought soil with a handful of perlite for increased drainage, but otherwise you should be good.
For example, a soil may be clay and loamy, or sandy and silty.

Loamy soil is a combination of sand, silt, and clay soils with added organic compounds. It is one of the best soil types for growing cannabis as it offers optimal water retention and drainage, and it’s rich in nutrients and oxygen. Downside: This type of soil can be expensive.
Cannabis soil needs to have excellent drainage. When you water your plants, it shouldn’t pool on top of the soil. If the soil has poor drainage, your plants will get sick and turn out subpar yields, or die.
• Medium-coarse
• Pros: Contains minerals and nutrients, retains water well
• Cons: Fair drainage
If your DIY cannabis soil is rich in organic material, you will likely not need to add nutrients to it. As a matter of fact, some growers make the mistake of adding manure and vegetable scraps to their soil to “fertilise” it. This results in soil getting “too hot” for the plants, hurting their development in turn. If you want to put your vegetable scraps to good use in your garden, you first need to compost them.
Vermiculite, just like perlite, is a heat-treated mineral you can use to make your soil lighter.It is also excellent at retaining water. Although vermiculite shares some characteristics with perlite, the two have opposite uses: Use perlite to increase drainage and airiness, and use vermiculite to increase water retention. Luckily, you can use both, as perlite and vermiculite work well together. Around 10% vermiculite is beneficial.

pH is a chemical scale that indicates how acidic or alkaline something is. This is important, as cannabis only does well within a small pH range. A good soil for weed has a pH of about 6.0. A pH of 5.8–6.3 will be fine, but if it fluctuates too far outside of this range, you will get diminished yields. If the pH is seriously off, your plants will die.

Soil is the medium of choice for most cannabis cultivators. Here is what you need to know to get the most out of your soil grow!
