I would recommend using Soilless Soil, it's available at a variety of Hydroponics stores and sometimes it can be found at Gardening Centres; the best stuff comes in a Black Bag and it usually doesn't feel that heavy (Not to me, to others maybe) but it's very compacted and the soil is excellent for growing.

I use Soilless exclusively and my Silver Haze are amongst the best that most people have ever seen as far as size, yield and even THC Content; If you are using DnF or a similar formula make sure you are using the correct stages, even I made this mistake or it will cut your yield down big time.


If you can I would also avoid using cubes as now that I stopped using them I'm getting much better results overall.
