From the link above:
These seeds will produce mostly high-CBD plants with between a 1:1 and 4:1 ratio of CBD:THC, ideal for people avoiding the psychoactive effects of THC. On average, 25% will have very high CBD with almost no THC. Then 50% will have both high CBD and high THC. The other 25% of the seeds will produce high-THC phenotypes. On average, 1 of 4 seeds will have 1% THC and from 13% to 23% CBD.
Wow, that's a range. Without a lab, how do you know what you're getting. Also, are you familiar with that seedbank. Info I found said it wasn't released to the public and if you found any they were not legit. Of course the info I read was a year old and things may have changed since then. I haven't seen any on the larger seedbanks websites so I'm always a little leary. Seems from the info anyhow that 50% of the plants come out 1:1 ratio like what I ordered from Royal Queen. What's on the way should at least be a good start.
EDIT - While I was composing the post I got a text update. Seeds arrived in my town. Should probably get them today! That's the quickest yet. I just ordered them Monday.
