Doctor Seedsman CBD 30:1 Feminised Seeds - 5
0% of 5 seeds germinated in a wet paper towel with filtered water. I started 8 other seeds and got 100% germination. I asked seedsman for replacements but they rebuked me saying that they were over 60 days old. I only ordered them in Dec 2025. Also I had perfect germination with other vendors seeds that were 18 months old. I will never be able to tell you about the flavor because the whole lot was duds.

Doctor Seedsman CBD 30:1 Feminised Seeds - 3
This is a first time I am growing seeds purchased from the 'Seedsman' seedbank successfully (my previouse outdoor experience with the photoperiod seeds wasn't successful last year). Both sorts are the CBD. The Doctor Seedsman 30:1 is on the left. Waiting it to start blooming. The plants on the right are CBD Raspberry Cough. I am using my compost made on the back yard and 'Alaska Fish' furtelizer to feed them. All purchased seeds germinated quickly. I am very happy of my results so far. Thank you for the great seeds!

It worked well outdoors although next time I will use supports, the plant seemed small but it produced more than I expected, it smells like pine, very pleasant, I hope to make an ointment to relieve muscle pain soon.

Very low and bushy. Requires a lot of trimming for airflow. Stalks/stems are very weak and thin and don't stand up well outdoors. Waiting to see if harvest is reasonable.

I've grown this strain twice and it ends up very leafy and not easy to trim. Non psychoactive so THC is minimal so that's nice

Doctor Seedsman CBD 30:1 Feminised Seeds
I ordered a 3 pk, and one seed sprouted. You guys sent me another pack, so I planted another...nver sprouted. So, the one that did sprout from the first pack, is currently shriveling up. It also looks mutated, very twisted looking. You guys typically have good starins, not sure what the problem is with this one. But thanks for the good customer service!

Doctor Seedsman CBD 30:1 Feminised Seeds
Like it says small plant, but robust. This smallest plant I had yielded more then some bigger ones. It is not sativa in effect, especially considering it says no cerebral / psychoactive effect. I'd say it should be labeled 70indica or more... First time I smoked I literally had to lay down. Maybe I got a freak pheno, but there is no high so it's cbd for sure. Just pure relaxation calming and soothing so I'd say you are right on effects, but those are indica and it harvested before Sept was over again that's indica lineage 100%. Anyways if you are looking for a good yielding high cbd strain go for this. Also it was done by mid Sept, so it might be a fast strain. Cheers!!
