All Great Damir!! you are a busy man 
Does O.Indica can grow there without protection or are you gonna protect it, i know guys here in my neighbourhood who tried (unprotected) but never went good for long time. Combination high Humidity and cold are killing here for them.
I hope they will live happy at your garden!

thanks mate! that o.f. indica was too heavy to take it inside in winter, so this spring i planted it outdoor, knowing that it will die in winter. it was in terrace and every time someone was passing by we should scream ,"no no, don't touch it" cause it has thousands of small needles that are hard to take out. i got another one that has no needles and that one will stay. i doubt it could survive winter here. once i planted few cuttings from this one, in very dry spot, under the steps , but it died. at its base it has some part that looks like wood already, maybe that part will survive, who knows. we'll see next spring. but i would love to have one opuntia outdoor that grows up, not just those full hardy which are mostly close to the ground.
