I read this post over and over again, I very much like what dp promises on taiga and Polar Light and I really want to buy them.
Thought that sending them an e-mail and asking them will not do any harm.
Here is their reply.
"We had some problems with a batch of Taiga and Tundra seeds. All problems have been solved with the seeds we sell now. "
I think I ll trust them, as if the plants do what they promise, it is money well spent.
