I think he lives and always lived in the US, even though he has spaniard parents. Maybe he moved recently to Spain I have no idea to be honest hahaha but yes he has been doing good work for decades

Unlike many people think, Spain is not cannabis friendly. Cannabis clubs are allow to sell if you consume it inside there or in your home, but theyre not allow to buy nor is commercial growing legal, its a loophole. But nowadays they dont break our balls too much. A couple of cannabis club owners went to prison when they became a big thing some years ago and thanks to popular protests their sentencing was reduced from more dan a decade to a couple of years which is still outrageous since cannabis clubs are legal, its just that they were moving "too much" and they probably had their own grows too.
Here's the thing, is not legal to grow, but if the plants are outside of public view and you can prove that its for you then its not punishable. (you need to provide how much you smoke aprox, they can take a sample of your blood to see if you are a consumer too and how much you have in your blood and I also have it in my psychological record so for me it would be easy, I can just bring that paper to court if they ever raid me).
Here all soils are peat and perlite, very basic, sometimes with some coco but yes, I have to buy perlite and add more because this area is humid and I need around 20-30% perlite, the rest is peat and my ammendments and a couple more things like arlite or vermiculite.
I would like to try compost and I made my own a while ago but it wasnt good, not balanced, also half of it got stolen when I had it drying on the window

but so far organic ammendments are getting me where I wanna be, kelp is trully amazing, and volcanic ash, and alfalfa meal... so many things you can choose from to make a great organic soil.
