Result with Kalashnikova is relatively good. I've noticed that defoliation during flowering is painful, but in my case it was really helpful.
Both strains are fairly good and it would be nice to switch them from time to time.
For the next grow I would either pick a larger tent or just grow one plant at a time in order to get more of decent buds. For the first time the entire process was pretty entertaining. I would definitely try more strains and techniques.
