About to soil I use.. I am using Compo Sana flower soil, thats the best I could find here around at the shops. There is no head shops in Turkey. Its possible to find some equipment, nutrients, etc. in local internet shops, but I've decided to use this soil from Compo Sana. In 2015 summer I was doing my 1st balcon experience with some witch seeds from the Turkish stuff, which I collected (Its almost impossible to find weed without seeds from the street sellers). Compo Sana did very good work, even for the witch seeds.. Althougt cannabis is having a very long tradition in Turkey, growers are not realy doing well growing, because of the several reasons..
I mix Bat Guano powder (from a Turkish brand: Turkuvaz), extra perlit, some red soil from the fields, and some humus component (another Turkish product), and a little bit of sea sand to the Compo Sana. So far thats all for my basic soil. As nutrition in water, I use some Canna Rhizotonic in first days. After 2nd week of vegetation I use a little bit Bat Guano in liquid form (from the same company: Turkuvaz).
I will share more info about my experience in following days,for sure.
Day 12: C4 is still leading baby. Yesterday I've ordered another automatic sort from FastBuds. Very nice dialog at mail traffic. Looking forward for the new experiences for my balcony..
