thanks . i didn't think that the soil with premixed fertilizer would be a problem because of previous grows .

i will see what will happen in time . of course i will not give up , that is not a option .

yeah, im using CT and air circuit include only CT. For ventilating box and "mixing" air in there i have another fans .

seedling don't stretch .

big thanks for advices . i will let u know how plant will turn up .

peace !
