my first outdoor grow.

Hey guys !
I have planned and prepared long for my first outdoor guerilla grow.
Just ordered 10x Kaya Gold fem , 10 x WW fem from Nirvana and some lowryders , just for kicks
My plan is to plant seedlings without growing them inside before (lack of space indoors) . Im am planing to plant them in mid-may when the weather allows me to do it here, in East europe ;D
and I have few questions for you, guys
buckets or holes? I was thinking holes, so my ladies gets their roots big and strong
is mid-may allright time to start? they will have about 25 weeks until the mid-october , when I plan on harvesting
and last and final one . any good place to order nutes for outdoor grows? it would be cool if they would ship world-wide

thanks guys, peace , love, unity !

Good idea here's how i do it, day1- clear the patch ,saw down trees ,dig post holes ,saw some posts(logs) to size. day2- bring chicken wire and roll of wire to complete the fence , ferts,lime,mulch,water crystals,tarp(for mixing),shovel, for 10 holes (per day). day3-plant clones in prepared holes mid spring.

yea, thats already how I am planning to do it. except I wont use clones, but seedlings.
any good recipe for soil?
