You may need to put all of your plants in containers if you don’t have great soil. Also, if you’re unable to perform the heavy labor needed to dig holes and amend soil, containers may be the only way for you to grow your own cannabis outdoors.
Indoor grows can be wasteful, using a ton of electricity to power all those lights, fans, and other equipment. The sun and the wind are free!
Sustained temperatures above 85°F will cause your plants to stop growing, while continued temperatures below 55°F can cause damage and stunting to plants, even death.
Cannabis plants require a large amount of nutrients over their life cycle, mainly in the form of nitrogen, phosphorus, and potassium. How much you need to add to your plants will depend on the composition of your soil.
Once you have an understanding of the climate in your area, you’ll need to consider a few things before planting your weed.
While some plants thrive in their native soils, which are usually one of the compositions listed above, cannabis plants are best grown in soil that includes a combination of the three consistencies above—this mixture is known as loam.
So ideally, the pH needs to be anywhere between 5.8 to 6.3. Your cannabis will still thrive if the pH is anywhere between 5.8 to 6.3.
Some of the natural ingredients that are absolutely crucial to the proper growth and development of your cannabis include nitrogen, potassium, and phosphorus.

When it comes to optimal growth for marijuana plants, perlite, and pumice are added to provide optimal and stable growth.
Ultimately, the best type of soil for marijuana needs to have the proper texture, ability to drain, and ultimately retain water.
However, when growing weed indoors, the only disadvantage is that it’s going to cost you time and effort to control the light, movements, humidity, and sunlight.
Any premium potting soil that is available in your area and does not contain too much added fertilizer. Choose a soil that’s finely sifted and does not contain a lot of bark or shredded wood. Buy soils from a garden shop that stores their pallets indoors. Do not buy bagged soil that has been setting outdoors getting weathered.

If you seeds are very high value, meaning you don’t have many or they were very expensive germinate the seeds before planting. Cover your seeds in moist paper towel or similar medium and allow them just enough time to crack their shell. Remove and plant before the roots emerge and become too delicate to handle. Tap water or distilled water can be used. Microbial products can be added to the water to inoculate the seed, use as directed.
These are normally used to starting clones but these soil alternatives also work great for germinating seeds.
I am not a microbiologist but the major players in this process are well understood and documented.
