Hello dear friend....
The best that you have to do to get the best results, is maybe to start an hydro grow, like in coco which is the best way to get high results about quality,, quantity, taste and high quality smoke. It is also the best way for u to start something in the hydro world, cause the easy work that it is giving to u, not like other hydro stuff.... which one can be complicated if you have electricity cuts.
If you want a Nice non hydro grow, you can also use soil, rich one, and start with minimum 7 liters per plant.
Good luke
