soil preperation

Growing cannabis indoors – soil preparation

After getting top quality seeds you should turn your attention to the the soil. Make sure you prepare the best soil available. Don’t cheap out on the soil. You will lose in the long run and live to regret it.

The fact is that unsterilised  soil will almost certainly contain parasites. Don’t go down that road. Instead get good soil for sale at your local garden and bedding centre. Get the soil that has these properties (or close to it for best results):

  • Make sure it drains well. Best stuff  has some sand i it and maybe also sponge rock or pearlite
  • Cannabis does not do well in acidic soil so the ph balance should be between 6.5 and 7.5. (If the soil is too acidic then the plant will tend to be predominantly male).
  • To help retain moisture and nutrients the soil should contain humas.

Here’s a good soil recipe:

2 litre moss with 1 litre sand and 1 litre pearlite to 20 liters of soil. Make sure the ph balance is Ok with a litnus paper test or a testing kit found is speciality plant shops.

If you need to raise the ph balance and half a pound of lime to each 10 litres of soil and it should raise it by 1 point.

If you use earth from outside be sure to sterilize it before use. Moisten it and put in the oven at 250 F for at least an hour. That should do it! Yes it will smell a bit but hey, you’re farmer now, it comes with the territory.

Now add one tablespoon of high nitrogen fertilizer, like Rapid-Gro, for every 10 litres and mix it up really good.

Or forget all that nonsense and buy some good soil in the first place.
