I've ordered from Highgrade maybe a year ago, grew the seeds to harvest, and read through their message board. From my experience and from the (lots) of threads I've read this is what you can expect:
THE GOOD:
1. You will get your seeds.
Stealth, prompt, friendly service. They will send a second set of seeds if you say you didn't receive the first. They ship to the US. I got my seeds within a week of their receipt of my payment through Track and Trace mail.
THE BAD:
2. You may wish you didn't get your seeds.
Apparently Highgrade jobbed out some seed production when their customer base started growing and one(?) of the breeders wasn't up to the task. I dropped by the forum a while ago and one of the people associated with the seed bank actually admitted in the forum that they'd been sending out bad seeds for some strains for a while (perhaps a year of more - how could they not know?). They claim they're fixed the problems and the bad seeds are out of circulation.
Unstable pheno's, too tall plants, hermies, plants not finishing (my problem), poor potency ...
One person (a woman I think) complained about her ... AK(?) stretching an extra foot or two in flower. Really bothered her because she had limited growing height.
Several people are discussing hermies, some have started threads on topics like - "Will pollenating one bud keep the rest of the plant from hermieing". There are probably more cases, but if people are like me they think they've done something wrong with the grow and don't say anything. Same reason a person might die when they're lost in the woods - embarresment.
My AK lived 22 weeks with clear trichs under 1000W HPS Horticulture. It never finished and I got a few bananas - possibly because the plant took so long to finish and the plant was trying to pollenate itself.
THE PRETTY GOOD LOOKING:
3. You may have found a fantastic seed bank with great selection at great prices.
Some of the members who signed up years ago, some commercial growers too apparently, say that Highrades genetics - that he breeds himself - are some of the best that they've had anywhere. Wide selection, a couple dozen strains, fantastic prices.
If Higrade either finds new breeders to help him produce good seeds again - to satisfy what must be a growing demand - or he shrinks his business to a size that he can handle all the seed production, and raises his prices, their seeds might get back to the quality that the long time forum members talk about.
4. They do not delete messages, on their forum, that point out problems with their business practices or seeds.
This is the most heartening thing for me when I see the growing pains that Highgrade has been going through - you can browse back years in their forum and every bad post is still there. I've read some and thought "there's no way that post is going to stay up", and I drop by a couple of weeks later and I read posts and think "Wow! That's the post I was sure they were going to delete".
It seems like they're working to fix their problems rather than cover them up.
Final Word:
I'm going to keep an eye on their forum and when/if the complaints stop and people start raving about the highs again I'm going to order a custom strain called "Electric Fruit Punch" which seems to have a very interesting high - they have a Smoke forum where the forum members talk about the highs that the strains give - great idea for a seedbank.
I'd recomend looking through their forum and seed list, if things look good try a strain that catches your eye.
