Best soil for growing weed indoors

In order for a cannabis plant to grow and thrive, it needs a good mix of both water and oxygen at the roots at all times! Too much water and the plant roots can’t get enough oxygen (lack of oxygen at the roots is why plants get droopy from overwatering) but on the flip side if there’s not enough water retention the roots can be injured from drying out too quickly!

Texture, Drainage & Water Retention

What gets the best results for growing cannabis is a soil with a light texture that is good at retaining water…but not too much!

Signs of Good Cannabis Soil

The fantastic thing about this soil formula is that the PH value is perfectly balanced. It also includes essential nutrients ideal for the growth of cannabis, flowers, vegetables, and herbs for up to 3 months. Besides, the formula is ideal for both indoor and outdoor gardening. You can read the instruction manual to be sure you are mixing it with other potting soils correctly.

The great thing is that you can either use it indoors/outdoor garden, making it great for individuals looking forward to planting a few of them in a limited space setting. Regrettably, you would be extravagant if you buy this soil and plant a few cannabis plants.

You must have in mind the number of plants you want to grow before making an order. This aspect will help you have a clear notion of the amount of soil you will require. For example, if you are interested in increasing 1-6 plants, it will be pointless to order a soil bale. Alternatively, if you are considering growing several plants in a large pot or container, then you must call a bale of soil or multiple bags of soil.
