Cannabis Potting Soil Recipe 2:

40% composted soil
30% worm castings
20% perlite
10% dolomite, guanos, goodies, etc.. i’ve also heard good things about “uncle
malcolm” brand soil from peaceful valley is good….

if you’re mixing organics with chem ferts, the plant will use up what the chem
ferts feed it first, then partaking afterwards in the organic nutes. the beauty of
organics is it’s almost impossible to burn your plants, and the taste is superior to chemical grown plants.

i use pure blend 1 – 0.5 -1 for veg and fox farm big bloom 0.8 – 3.0 – 1 for
flowering. they’re expensive but the plants really like it. sometimes i’ll make a tea out of worm castings & guano

 

 

1. Making the base
The first step when making the right potting soil mix for growing weed is looking for high quality organic soil, which will act as the base. The base soil can be defined as the regular soil that will be used in the pots without any other additives. Selecting the right base soil is very critical when it comes to growing cannabis. Most beginners will fall into the trap of cutting corners when choosing the base soil. However, this is detrimental to their venture considering that cannabis grows well in aerated and permeable soil. You should look for good organic soils that tend to be more expensive because they have the right ingredients. A balanced organic soil will usually contain several ingredients, such as peat moss, bat guano, soybean, earthworm castings, soybean meal, pumice, compost, lignite, green-sand, glacial rock dust, oyster shell flour, k-mag, coco fiber, perlite and leornardite. If you find a local mix with most of these ingredients, then you should use them as your base.

2. Adding other nutrients
Considering that it might be difficult to find an organic soil with all the appropriate nutrients, you must consider supplementing it. Some of the ingredients that you need to add include steamed bone meal, organic worm castings, bloom bat guano, blood meal, rock phosphate, Epson salts, sweet lime or dolomite, azomite to provide the plant with trace elements and humic acid. Most of these ingredients are readily available and provides the right nutrients for your cannabis. One ingredient that you may find hard to get is the worm castings, but you should never fail to use them. The beauty is that you do not need a soil conditioner if you use worm castings.

3. Mixing up the ingredients
It is very important to mix all the ingredients well for effective results. You can place a tarp on the patio or garage or sweep the floor and use it directly. This is usually a strenuous activity, so be careful not to pull a muscle. Some people may rent out a cement mixer to avoid the hard labor, which is fine. The method used to mix all the ingredients properly does not matter, as long as the end results are perfect. You should start by pouring a few bags of the base soil on the tarp or floor and then making a mound. Add the powdered nutrients in the center of the mound. Cover these with more base soil and continue alternating the two until everything is added. After this, turn the soil thoroughly using a shovel until it is thoroughly mixed. The end result is the perfect soil mix for growing weed.
