I planted F6 Whites and Purples and F4 Whites, I got 50% germination on the F6 Purple and F4 White. I got 1/6 on the F6 White about a 17% germination rate there. Most people were having troubles with them. Best of luck.
Edited to add: Just noticed the F6 Purple has another seed coming up, that will make 4/6, so somewhere around 67% germination rate for that one.
Edit to correct & symbol to % in the above sentence.
Welp I can't seem to get lucky with these seeds. I've tried two times and both times I had terrible germ rates. The few that did germ were helmet heads. I'm gonna try one more time I think.
