Anything listing auto Stardawg or feminized Stardawg is not Stardawg. There are a lot of seed banks that just slap a popular name on seeds, or make crosses of popular clones or strains but fail to advertise the actual genetics behind them. For example, there are a ton of seeds sold as Girl Scout Cookies that look nothing like Girl Scout Cookies and likely aren’t related in any way. If a seedbank doesn’t list the breeder of their seeds, I’d stay away.
For the real deal Stardawg, they are made by Top Dawg and you can find Stardawg F2 seeds here:

They are quite pricy and they do tend to sell out quickly.
Greenpoint seeds is another option if you’re ok with a Stardawg cross. Most of the strains available through Greenpoint were sired by a stud Stardawg male and have a very good reputation among growers.
