What's the best soil for growing weed indoors

If you’re planning on planting a large container cannabis garden outdoors, Roots Organics Formula 707 is a versatile and capable option. An organic soil designed with greater water-holding capacity, Formula 707 contains ingredients and beneficial microbes specific to using larger containers.

If you’re digging through the literature on growing weed, you’ve probably seen the term “super soil” come up quite a bit. Coined by the legendary grower and seed producer Subcool, the term generally describes a neutral organic soil base that’s been enhanced with a comprehensive range of “amendments,” i.e., added nutrients and microorganisms. Using a super soil eliminates the need for liquid nutrients as your cannabis plants grow.

Your soil’s nutrients and the water you provide need to link up to be available for and absorbed by plants’ roots. Biochar, a carbon-rich charcoal amendment, not only facilitates this process but it also provides a large surface area for microorganisms to live and thrive. Red’s Premium Biochar-based soil thus creates an ideal “habitat” for all the living beings that help your cannabis plants reach their full potential.

Red’s Premium Biochar-Based Soil

Designed for indoor and outdoor cultivation, Happy Frog potting soil takes care of young cannabis plants’ essential needs, from correct pH levels to balanced nutrients, including a vital combination of microbes and fungi from earthworm castings and forest humus.

But just as important as what’s in this soil is what’s not: less perlite, less pumice, and fewer amendments. This makes Formula 707 a highly customizable soil, allowing you to add your topsoil and liquid nutrients at various growth stages depending on your cannabis plants’ needs.

Red’s Premium is another all-in-one, ready-to-use soil blend. But what makes it one of the best soils for weed is its stand-out feature: biochar. Biochar is an amendment that excels at protecting and promoting the growth of bacteria, fungi and other microorganisms that are essential for root development and strengthening your plant’s immune system.

Still, Formula 707 has enough nutrients to last 10-14 days before you need to add anything. And for convenience, you can use the soil bag itself as a pot. Just cut off the top, poke some holes in the bottom, plant your seedlings and you’re ready to grow.

If you are a beginner grower, you must purchase your soil from a garden store. Did you know that the vast majority of expert growers also buy their soil? A handy tip when talking with a store employee is to ask about the right kind of soil for tomatoes. It is an excellent option if you feel uncomfortable disclosing your desire to grow weed!

The amount of work you must do depends on the balance of your existing soil. For instance, if it has high amounts of clay or sand, you’ll have to add large amounts of organic matter several times a year. You can add a two-inch layer of organic matter onto the surface of the garden. Then, you should work it into the first couple of inches of soil.

When you water the plant, it moves essential nutrients and minerals to the roots. Then, they travel to the rest of the plant. Water cools overheated plants down and is a critical ingredient for photosynthesis. The best advice we can give is to water the soil until it is moist, but not wet to the touch. Overwatering aids the growth of harmful fungi, which can result in root disease, so exercise caution!
