The texture, drainage ability, and water holding ability are arguably the most critical aspects of marijuana soil. Your plant will not produce a good yield if it doesn’t have the right mixture of water and oxygen in the roots 24/7. If there is too much water, the roots won’t get enough oxygen. If there isn’t enough water, the roots can dry out quickly and become damaged.
This is a great option if you want to nurture your crop from seedling through to harvesting. This Espoma soil contains excellent nutrition for early-stage growth. You will need to begin with small pots, before transferring your growing plants later. It contains peat moss, perlite, and peat humus – not to mention a hose of nutrients that aid strong root growth.
This is probably the most commonly purchased amendment and is ideal for practically any soil mix. It consists of airy ‘rocks’ known for their white hue. Perlite looks a bit like popcorn and improves drainage while adding oxygen. Use 10-20% to improve water retention. You can go as high as 40%, but you risk leaching nutrients faster. If you use Perlite and Vermiculite, don’t go above 50% for the two combined.
It is normal to go to your local garden store full of enthusiasm. That is until you are knocked back by the enormous number of options. First of all, please note that buying it in bulk could be a mistake. There are no certifications or standards attached to soil quality. Believe it or not, some of these sellers provide you with soil from construction sites. They could even sell soil excavated from basements!
Battery acid and hydrochloric acid have a pH of 0, while liquid drain clearing fluid has a pH of 14. Ideally, your cannabis soil is slightly acidic. Most experts believe that the ideal pH is 6.0. However, you are on solid ground if your soil’s pH is between 5.8 and 6.3. Your crop will survive outside of this range, but the yields are likely much smaller. If you stray too far from the 5.8-6.3 range, the plants will die.
Best for Seedlings – Espoma
Overall, you can’t go wrong with an organic super soil and fertilizer mix. The super soil offers the ideal blend of nitrogen, phosphorus, carbon, and a myriad of other nutrients. You can make them yourself, but once again, we recommend investing in store-bought pot 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!
If you don’t have a suitable patch of earth to make a garden, containers can be placed on decks, patios, rooftops, and many other spots. If needed, you can move them around during the day to take advantage of the sun or to shield them from excessive heat or wind.
Relying on the power of the sun, you won’t need to spend a ton of money on an outdoor grow. You’ll need some soil, fertilizer, seeds or clones, and maybe a small greenhouse to get them started. You won’t need to pay for electricity for lights, AC units, or dehumidifiers, and you can even collect rainwater.
Some growers plant in containers on balconies or rooftops that are shielded from view, while some build heavy-gauge wire cages to keep thieves and animals at bay. Whatever you decide, think about how big you want your final plant to be—outdoor cannabis plants can grow to 10 feet tall or even more, depending on how much you let them go.
Here are some important considerations before starting an outdoor marijuana grow.
Buying the right soil for an outdoor cannabis grow
In general, 5-gallon pots are a good size for small-to-medium outdoor plants, and 10-gallon pots or larger are recommended for big plants. Regardless of size, you’ll want to protect the roots of your plants from overheating during warm weather, as pots can quickly get hot in direct sunlight. This will severely limit the growth of your plants, so be sure to shade your containers when the sun is high in the sky.
Growing marijuana outdoors is great because you won’t need to spend a ton of money on it and you can rely on the power of the sun. If you have access to a sunny spot in a private yard or even a balcony, terrace, or rooftop, you can grow weed outside. You will be tied to the sun and the seasons and local weather, but you won’t have to spend a bunch of money on equipment and utilities like indoor growers.
It’s fun and relaxing
How to set up your outdoor marijuana grow
Sandy soil is easy to work, drains well, and warms quickly, but it doesn’t hold nutrients well, especially in rainy environments. You’ll want to dig large holes for your plants and add compost, peat moss, or coco coir, which will help bind the soil together.
There are also commercially available soil blends that already contain the proper mix of these types of ingredients.
