Usually yes.. I however did not have this much luck with Jillybean or Pandoras Box. I had bought 5 packs of each and never found a single Jillybean pheno worthy of writing home about.. in fact I had encountered mostly males and a wretched "smelly armpit pheno"... it does exist... with Pandoras Box.. similar results.. mostly males which is so non-typical of any of the TGA gear.. but it did happen. Usually when I pop a pack of TGA seeds I can get mostly females and or twins that add more females depending on the strain.. so I still am a farm believer of dropping/popping an entire pack if you want to really find a keeper.. run all 10. Because sooner or later it will happen to you that your luck will run out. With TGA gear I usually get 60-70% females.. this was not the case with Jillybean or Pandoras Box.
it's funny that you mentioned the "Void." I actually received a free pack of that when it was released from Subcool.. ran it and it was my least favorite TGA strain at the time. My phenos mostly tasted of butane and cracked pepper. Nothing like I expected. It was potent and yielded well..but noting fruity at all about those.. at least not mine. I really disliked it.
On the flipside however.. I've popped one single seed, or 2 at a time..of other strains and come across amazing phenos without even trying to look. My single seed grow of Chernobyl produced a better looking pheno than anyone at the time was showing online.. that pheno was incredible. Have had similar luck with a couple of other strains too...when i used to only grow 10 plants at a time.. I would pop one of these.. couple of these.. etc.. try to show some diversity in the lineup.. but when it all comes down to it.. it's still simple probability. If you''re growing 10 plants from some really good genetics you are bound to find at least a couple of really nice looking gals that hold some special traits.. might not be the specific strain you are looking for.. but with seeds they can't all be winners.. they can't all be rockstars.
& then there's that really special one... the one plant that you find that is maybe 1 out of 100. The keeper that you consider to be a true elite. The plant that you come across and you never want to let go. I've only had a few of those in the 10 years I've been growing indoors. My old Space Princess which was a Sputnik 1 x C99... and my current Bodhi A11g, as well as my current Starfighter f2... phenotypes so special that you know that if you lose it, it would be damn near impossible to find again without running multiple packs over and over... which may not be possible due to the availability of the seeds.
I'm currently on a pheno hunt for a nice purple plant that is was reminiscent of a pheno of Jackpot Royale that I had. I popped a pack of Alphakronik's Cheshire Kush, the entire pack as well as 6 of his Snozzberry to create a small pool of contenders that I am running with the only intention and goal of finding the best one. The LVPK pheno I saw from the Jackpot Royale was absolutely amazing in all regards. Very dense, short, finished fast, had a grapey, berry like smell. I really liked it. When I saw the lineage for the Cheshire Kush.. I jumped on it immediately.
To me the thrill of the hunt is half the fun of growing. But then again, I am a hobbyist. I do this strictly for fun.
