Texture & Consistency:  Soil consistency, texture and content of your mix are important factors when choosing the right soil for your garden. This will ensure your garden gets the most out of your feeding and watering schedule. When choosing a soil mix the best way to test the consistency is to grab a big handful of moist soil and squeeze, this will create a clump in your hand, if you can move your hand around and the clump quickly dissipates and feels light and fluffy but still has some grit to it then this will probably be great for cannabis. Cannabis loves a medium that drains well but still retains a good deal of moisture, you want to be watering every three days not every single day.

pH:  Cannabis grows best in a soil that is around 6.5 to 7.0 in this range nothing is being locked out and the cannabis plant is able to fully absorb all available nutrients. You can buy a soil pH test kit at any garden store, but most bagged mixes are already at a pH of around 6.5.



Most bagged soil is made of humus and organic matter that is mixed in to help retain nutrients and feed your plants for the first few weeks of life. There are also planting mediums that look a lot like soil but are actually soil-less, made with 100% peat moss and have very little added nutrients. These mixes usually have added perlite (volcanic rock) to aid in aeration of the mix.



One bagged soil that is making a name for itself is Fox Farm: Ocean Forest. This mix has a good amount of added organic amendments that supply enough nutrients to get you through the first couple weeks of active growth. It is comprised mostly of forest humus which retains water longer and helps to conserve water resources.


The best gardeners have learned exactly what their plants are going to need from stage to stage and mix their own “super soil” which can be rich enough to supply nutrients all the way through harvest!
