potting soil for weed seeds

In hot climates, sandy soil should be mulched to help with water retention and to keep roots from getting too hot.

Heavy rains and high winds can cause physical damage to plants and reduce yields, and excessive moisture can lead to mold and powdery mildew, especially during the flowering stage.

If you’re growing weed outdoors, it’s great to find a community of cannabis growers in your area to see how others are growing in your specific climate. Local climates vary, so it can be helpful to see what strains thrive where you are, and also when other growers are popping seeds, harvesting, and more. You can also join online forums or Social media groups, but a great place to start is your local grow shop.

Sandy soils

The sky’s the limit with outdoor plants—you can let them get as big and tall as you want, as long as they’re manageable. One plant can potentially yield between a half-pound and full-pound of dried weed! Growing a handful of hands for yourself is more than enough. With an indoor grow, your space is a lot more restricted.

Environmentally friendly

Low costs

Garden plot: Probably the most common outdoor growing spot, many will plant cannabis alongside other growing veggies.

pH value

Perlite is the most widely used soil amendment. Perlite consists of very light, bright-white rocks that greatly improve the drainage and airiness of the soil. Perlite also has decent water retention. To amend your soil with it, add 10–15% of perlite. You can add more, but then your soil may become too light and nutrients may leach out. Good-quality commercial soils often come with added perlite.

1. Sieve the compost to remove larger chunks.
2. Soak the coco coir peat in warm water. Check the directions of the product to see what kind of volume you will be getting.
3. Use a bucket and mix the coco coir peat with the vermiculite.
4. Add the compost.

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.

The above is a basic soil recipe that will serve you well for most grows, indoors and outdoors. But you can further enhance your soil mix by adding organic fertilisers.

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.

Fox Farm’s specialized line of soils for cannabis are some of the most widely acclaimed grow mediums available. If you’re beginning your grow journey from the ground up, Happy Frog is an excellent soil to nurture seeds and seedlings.

Nature’s Living Soil Organic Super Soil

From planting seeds to harvesting buds, Nature’s Living Soil’s Organic Super Soil has you covered through cannabis’ entire grow cycle. Reviewers love the ready-to-use simplicity this soil provides: just plant, water and wait. For those growing on their own for the first time, this is one of the best soils you can buy.

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.

If growing cannabis is an art, then the soil is the canvas, paint and even a little bit of the brush. As your “grow medium” (the material that your plants grow in), the balance of nutrients your soil contains shapes how your plants grow, how fast and abundantly they flower and how many buds they yield.
