Potting soil for weed

What is the best potting soil for auto-flowering weed?

I have learned that good potting soil for roses or other flowering plants is just fine. So why make things more complicated by trying to mix your own soil? Don’t buy cheap potting soil but just take the best potting soil available for flowering plants.  I have bought a sack of soil for 12 dollars at our local garden center.

If you still want to do things the hard way, here is a cannabis potting soil recipe.

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.

Pots for growing weed

I don’t know if it is better but I always start with a small pot to transplant it later to a larger pot. One germinated weed seed per pot. Just save the plastic pots of the plants you buy for your garden center for later use. After cleaning them with water and chlorine you can be sure there are no traces of fungus or insects left behind and you are ready to plant your cannabis seed.

Unboxed my 300W LED Growlight

With a quality LED grow light and an average-to-good grow, you can expect yields of about 0.5 grams per watt. It depends a lot on strain, and pro growers can yield even more, but that’s a good rule of thumb. As an example, a 300W LED (300W true power draw, not an “equivalent” wattage) would yield about 150 grams (5 ounces) of bud on average.

Today’s LED models are much better for growing weed than the ones available even half a decade ago. They have wider spectra of light (instead of purely red and blue light) which results in greener, healthier growth and better looking buds. Additionally, LED manufacturers have developed specialized lenses to point light directly to the plants and increase penetration, resulting in bigger yields for the same amount of light compared to older models.

LED grow lights are often compared to HPS grow lights and each type of grow light has pros and cons for cannabis growers. Here’s the quick summary to help you decide, but you can also read more deeply into the differences between the two here.

​Choose LED lights for growing weed if:

  • You want to use the most cutting-edge indoor cannabis grow lights with a customized spectrum of light
  • Quality (THC potency, smell, trichome development) is more important to you than yield/watt.
  • You don’t want to deal with an exhaust system or ducting, and would prefer to just hang your grow light over your marijuana plants and let the lights cool themselves


Why Does Weed Smell Like Skunk?

The Best skunk in the worldCannabis strains vary widely in many respects, including their aromas. From herbal to citrus, and everywhere in between, each strain is unique. One trait many strains share, however, is a distinctive odor that resembles the pungent smell of a skunk. In fact, one of the most popular strains of bud is named after the critter because of this. But what exactly causes so many cannabis strains to smell like a skunk?

Why does weed smellWhy Does Weed Smell?

A group of compounds called terpenes cause the various odors that come from weed, of which there are thousands of different types found in nature.

A variety of plants produce terpenes, and most of them have an overpowering smell. On weed, it’s the terpenes that give the herb its unique and rich fragrance.

Studies reveal that there are at least 120 different terpenes found in the plant.

Each terpene smells different than the next one. As a result, cannabis strains vary widely in their aromas from strain to strain depending on what terpenes are present, and in what amount.

So the more lemony terpenes are in a strain, for example, the more lemony the batch will end up smelling. That’s the reason you can get anything from earthy herb to bud that smells like oranges.

Why Does Weed Smell Like A Skunk?

Why Do Skunks Smell?
Skunks are most well known for two things: their black and white fur, and the ghastly smell they emit from their backsides.

These two features work in concert to fend off predators; their distinctive coat serves as a warning that if you cross the creature, you’re in for a foul-smelling surprise.

The skunk has scent glands that produce their noxious spray. The concoction these glands produce is a mixture of chemicals that contain sulfur, and the most prominent of these chemicals are compounds called thiols.

Thiols are characteristically pungent, often smelling of garlic or rotten eggs. It’s these that make the skunk’s spray so vile. Like terpenes, there are many different types of thiols. The particular combination of thiols present in skunk spray is what makes it so easily identifiable.

So what is the link between terpenes and thiols that cause some cannabis strains to smell like skunk? The answer is that it’s rather coincidental. Some of the terpenes present in cannabis happen to smell like the thiols in skunk spray. If these skunky terpenes are low in a particular strain, the resulting bud won’t smell like skunk at all. But other strains will have terpenes that make it extremely skunky.
