Advice from indica experts please...

I am basically a sativa guy, now growing bunch of Sativas and hybrids from Sannies, also growing Nothern Lights #5 from PeakSeedsBC.

Want an indica or 2 with medicinal values or a good knock-out if I need it.

I don't know how much "medicinal" my NL #5 will turn out, so I want to add one of the Kushes as a back-up or variety to my medicine cabinet.

Considering following strains from breeders I dealt with and I trust:

Huckelberry Kush

Caramel Candy Kush both from Sannies (by Professor)

also

Kush Berry

Kush Skunk

Kush Notrhern Light crosses from Peak Seed BC

Which of those should I go after for pain relief and insomnia?

I am concerned about effects, not much about taste in that particular case.

Kushberry is a very good cross from Peak. It fits the bill. The NL is a bit functional but relaxing still and in the body. I don't think the NL will really KO you unless you let it get seriously amber.

I just asked MikeJ (PeakseedsBC owner & breeder). He recommends Kush X NL cross.

Haven't grown his Kush x NL but it's probably good too.

Og#18 from Reserva Privida will do the trick.
These buds are potent.
I happily endorse this strain.
