Growing weed can be an expensive and highly competitive business, and so it really is important to stay one step ahead and
maintain an up to date knowledge on the best marijuana growing techniques. Reusing old soil has actually shown to be a very effective action and comes with numerous advantages.
Contrary to popular belief, it really isn't necessary to venture out and purchase new soil every time you pot a new plant that is, unless something was wrong with your last batch of soil, such as an infestation, in which case go and buy new soil straight away. In fact, reusing old soil can actually be more beneficial than using fresh stuff.
Look after your soil
Cannabis is infamously greedy when it comes the nutrient intake, whether its calcium, potassium, or sulphur - your plants want it all, and lots of it. By making sure you have healthy soil to start with, you can eliminate the need for having to restore it prior to using it again. All you have to do to do this is take care of your soil properly. Composting, mulching, regularly fertilising and watering your plants are really all you need to do. Essentially, if you soil is correctly looked after, you won't need to do much when you go to reuse it.
If you want to go a step further, companion planting is another way to keep soil nourished. If you're going to do this, make sure you have a pot bigger than you normally would so both plants have room to grow. An example of a great cannabis companion mix would be planting alfalfa, clover and marigold in with your plant(s).

As I mentioned earlier, if your soil has become diseased or appears unhealthy for whatever reason, the most beneficial thing you can do for you and your garden is to bag it and throw it away. Reusing this kind of soil is a sure-fire way to hurt your grow and can spread pathogens (if that's what is wrong with your soil) throughout your entire garden.
When reusing soil, the best way to do it is to use half old, half new. This will improve the texture and fertility of the soil, as well as save you quite a bit of your hard-earned cash without compromising on quality.
All in all, it's a great thing for your wallet and for the planet to recycle your soil. So next time you think about going to buy some new soil, look at your old stuff first, and use it if you think you can.
