My soil mix, what do you think

[necro001]

I've made my soil mix for the next session:

40% universal potting soil (biologic)
20% worm casting
20% perlite
20% coco

i will use plagron nutrients (alga series). the soil is made basically for the vegetative stage.
i use specific nutrient for calcium and magnesium in case of deficiency (i think they're from bionova)

Not a bad start...what is biologic universal potting soil?

 

[necro001]

well...it's normal potting soil, but with the biologic certification. it's the only kind of organic soil that i can find in my country. it has some nitrogen (<1%), fulvic acid, a good amount of carbon and a ph of 7.

The universal potting soil sounds pretty good. Biologic is prolly your countries "organic certifaction". 'Might wanna bump up the amount of castings to 25%, but not necessary. Try to find large size perlite if possible too, size #3.

Number one thing to do is pH your mix after you make it. If it's pH is below 6.5 you might want to add some lime. (unless the variety you grow likes a lower pH) Personally I try to get my soil pH around 6.8 -7 so i do not have to pH my nutrient solutions during the grow. The choice is yours.

The only other suggestion I have is to think about micro nutrients. If you can get any rock dusts or silicate clay minerals, even from some quarry or stream bed close by, this will do your plant a world of good. Kelp Meal and even freshly harvested seaweed that you dry out your self also provide many micro nutrients.
