I'm about to harvest a sativa dominant pheno Sugar Punch which I think might well be the strongest sativa I've grown yet, seen lab test reports for that pheno of 23% - I will report back when she's done, 11 weeks now, will harvest her about 12 (I want the full strength, hopefully without sacrificing some 'high' for 'stone').
The best so far for me was a 13 week flower green killing fields - hard to tell her strength accurately though, as one of the main signifiers of her potency was how much stronger she was than the tall purple phenos which have been widely said on forums to be subjectively mild.
That's the thing though with sativas isn't it, the effect is often very subjective - certainly more so than the a good old 'kicked to the back of the chair' indica. I personally am looking for a rushy racy speedy type effect from a sativa - which I'm still yet to find fully to my satisfaction. GHS Super Lemon Haze (SLH) was amazing, tasty, and strong; but had a definite stoney side to it. The SLH longer flower phenos had the energising side, but the impact strength was not the same.
The first of the sat dom pheno Sugar Punch (SP) that I'm currently smoking is strong. Possibly the equal of the Killing Fields mentioned previously, but the SP is like the SLH in that it has a stonier side to it. I am left energised - and have done loads of odd jobs round the house whilst high on it, that I'd been putting off the whole time I've been waiting on this weed to be ready - but I'm also clearly sedated too, dopey externally.
I like the strains which don't 'dope' hardly at all (and in fact do the opposite). I remember some weed I got sold commercially a few years ago as Super Skunk that was not dopey at all. A bowl of that - particularly if it was the first of the night - would stop you sleeping. Reading on Super Skunk it shouldn't have been possible though. Some Chiesel a mate grew was super energising and non dopey; but all the 4 I grew were indica dom stones.
I was looking at the Soma Amnesia Haze like you. Sounds amazing. I will certainly grow her at some point - but that price is high, and puts me off I must admit. Chosen Sannies Jack and his Shackzilla (Shiva Skunk Jack X Super Silver Haze) for my next grow - as I'm super confident with his genetics, and this will mean I have grown all his sat dom fems so can offer comparison. Once I've picked my fav I might run some alongside the Amnesia see how they match up - might even do that as my first grow of next year (treat myself to the Amnesia seeds for Xmas lol).
stay frosty bro!
