I have tried the following seed companies:
TH Seeds - The HOG
This strain was garbage. It grew and yielded fine, but lower quality buds. I would guess 5-10% THC
Cali Connection - Dead Head OG
This was the best pack I have ever cracked. Don't go buy any of these because they are a nice little unknown covered by lots of haters. 2 of my standard cuts are from this pack and very different. A local collective had them tested. The scored 25.3% and 24.1% respectively and are great smokes too. Very chemmy and smooth OG undertones. I highly recommend these. Medium Yielder
Cali Connection - Chemdog #4 OG
Very strong almost lemonade flavors. Some were low yielders and some above average. The tastiest were the low yielders. I grew Chemdog #4 next to these and it yields much better, but some of these phenos had a better flavor and stronger high. I have eventually let all of these go.
Cali Connection - Sunset Limited (feminized)
A Jamacian x to Blackwater. Like you will find with most feminized...the are garbage and a risk. They almost always through some pollen, the question is just when. Some great grape soda like flavors and monsters outside, but not keeper quality flowers.
Alien Genetics - Lemon Alien Dawg
These plants looked amazing will growing, but did not test very high. My most frosted one tested at 14.1% and the buzz made you feel kinda down. I did have a few herm. One small yielding pheno had a very nice cherry to floral flavor and a strong body buzz. I kept only this cut. I did make some crosses with one of the males and the offspring exhibited a strong F1 hybrid vigor. Above average to small yielding depending on Phenotype. I would pass on this one.
Alien Genetics - Alien Rock Candy
Great flavor. The purple kush genetics shine through in the flavor dept. small yielder, but a pleasant body indica. My partner unfortunately let these die. I would be interested in another pack and the Ewok.
Bodhi - Ancient OG
Unique almost blue green color. Very Frosty, but nothing special in the smoke. I would have to say the Ancient and others are second tier to my Deadhead cuts. Small to medium yields. I would probably pass on the Ancient. I still have the Goji, Sunshine Day Dream, Drunken Unicorn, and other Bodhis to crack one day.
Bodhi - Head Trip
Killer heady buzz. Some long flowering phenos and a couple around 10-11 wks. Could yield big outside. good yields inside. Unique flavor. I kept one and made f2's.
DNA - Holy Grail OG (fems)
Weak, pathetic looking garbage. One had a decent smell, but what a joke. All 6 were the same. It is sad that this is what is getting sold representing the cannabis cub winner. Come on DNA how could you???!
When I try seeds, I always crack the entire pack and hope to get 1 good male and 1 female. I have a Rare dankness Og Ghost Train haze #1 that I will do next. I want to make some crosses to Chemdog D, a killer MK ultra cut (hit 28.9%, seriously), head trip, and others (GSC). When I tested these professional seed packs, I also tested some ametuer ones that I made with the LAD male and they yielded much better and were at least equal in quality of the best other ones in smoke. Seeds are fun, so buy some and make your own too. Hope this helps.
My recommendations
(buy only regular seeds in original breeder packs!):
Cali Connection - dead head, chem valley kush, larry, ogiesel, sour d, raskal
Rare Dankness - no experience with these, but a good feeling
bodhi - any, look for the appalachia male
Top Dawg - you have to watch for these, they go quick. If you can get chem clones, maybe buy somethine else
OG Raskal - No exp, but no hate uttered, prob a solid bet. Wifi if you can
