seed starting mix for weed

These small, black, fly-like bugs feed off your plants and lay their larvae in wet topsoil.

• Going organic

Overwatering can also occur when a plant’s container is too big or too small. When growing a small seedling in a big pot, the excess soil can hold water for days in areas untouched by the plant’s roots. What you’re left with is a big container filled with wet soil that’s not only robbing your plant of oxygen, but also creating a breeding ground for fungi, bacteria, and pests.


Black or red in colour, spider mites live on the underside of leaves and sometimes spin protective webs around healthy foliage. They love hot, dry conditions.

• Pythium and Fusarium

Cannabis seeds need four things in order to germinate: moisture, warmth, darkness, and time. To ensure you grow healthy seedlings, germinate your seeds using one of the following techniques.

From cheap nursery containers to sophisticated smart pots, growers are spoilt for choice when it comes to picking the right container for their cannabis plants. And while it’s possible to grow great weed in cheap plastic propagation containers, there are a couple of things you’ll want to keep in mind when choosing pots for your weed plants.

For this, you will add the same inputs as we do for the regular gardening soil mix. Every cubic foot of soil you mix up, you will want to use roughly a ¼ cup of each of the below inputs.

It turns out, they aren’t! There’s actually very little difference in the soil you will use to start your seeds and the soil your plants will grow in until they are harvested.

For those looking to start their seeds, you may find a lot of different information about the proper soil to start seeds in. Of course, we’ve all seen the over-priced seed starting mixes at our local garden stores, but are they really necessary?


By using the below base, amendments and minerals for your seed starting soil mix, you will be well on your way to harvesting a bountiful crop of fruits and veggies.

Now, we will use almost the same minerals as we would with a regular gardening mix. For every cubic foot of soil, you will want to use a ½ cup of each of the below minerals.

These ingredients will make up the base of your soil. You will notice there are much more aeration and peat moss in a seed starting mix than a regular garden mix. Since your seeds do not have developed root systems yet, the more aerated and drained the soil is kept while your seeds germinate, the better.

As mentioned earlier, it’s not totally necessary to mix up a seed starting mix, especially if you intend to directly sow your seeds into your garden plot. In fact, some plants should be directly sowed for best results, such as carrots, onion, potatoes, and many other root vegetables.
