Man, I sure have heard a lot of good things about Sannie's seeds, and Sugar Punch in particular lately. It really makes me want to give them a try. Last time I was hearing this much good about a seedbank it was about TGA, and I haven't been let down in the least from them.
It sounds like you know your shit man, and it sounds like I need to start looking at Sannie's seeds.
Got to restrain myself a little here because I'm a little biassed when it comes to Sannie seeds. No relation whatsoever besides being a very happy customer and posting on his (Dutch) forum occassionally.
That said, Sannie seeds are in many ways the best (imho and fairly limited experience with commercial seeds). My avatar is from my previous run, Sugar Punch. Had two different phenos, smoking it for over a month now. Can't get enough of it, still suprised I grew such quality shit myself. Best yielder I had so far and by far (.95gr/w fully organic with mostly sannie products, he sells organic nutes in a starter package, usually called Sannies-way, but I refer to it as growing for dummies - no ph- ).
Sugar Punch was sold out, something went wrong with the second batch, they are supposedly available again within a couple of weeks/months. Lot of people waiting on it as it's one to grow "again". I only had green phenotypes, but there's a pink and purple version too. That for many is actually a downside, but since its for personal use I like the variation. If you want to see some more pics of the SP let me know.
Currently got 5x Liberty Haze from BF and 2x Kollosus from Sannie. Wasnt planning on buying sannie seeds this round because the ones I like are sold out, but the ones from BF didnt germinate as well as expected (only 1 out of the first 5 seeds). Although completely different strains, the Kollosus is clearly so much more eager to live. I decided to always have a couple of Sannie seeds in my room until I find another just as reliable, as backup.
Sannies Jack is supposedly a great smoke, but the time needed for flowering can vary a lot, weeks, so I wouldnt recommend that one.
