A few months ago, I had the chance to get my hands on some seeds from a private collection – and among them was something special: a pack labeled as regular Super Lemon Haze by Greenhouse Seeds, purchased around 2010. Though not in its original packaging.
At first, I was confused.
Regular seeds from GHS? I’d only ever known them for their feminized lines.
Did they really release Super Lemon Haze as regulars back in the day?
Naturally, I started digging.
Turns out Greenhouse did offer some regular seeds back then – strains like Neville’s Haze, for example. The friend who gave me these had quite a few others from those older GHS lines in his freezer.
Seedfinder also lists Super Lemon Haze as having been available in both feminized and regular form at one point in time.
But some folks were skeptical – they were convinced GHS never released SLH as regs.
Now, Super Lemon Haze was one of the very first strains I ever grew, about 15 years ago. So for sentimental reasons alone, I had to get them.
Even after the seeds found a new home with me, I kept researching their origins.
My friend was 100% convinced they were legit regular Super Lemon Haze from GHS.
But I couldn’t find any real proof online.
I even went back through archived versions of the Greenhouse Seeds website using the Wayback Machine between 2008 and 2011 – which honestly sucked, since so much of it was built with Flash. (Younger growers may not even know what Adobe Flash was – but trust me, it was awful.)
I did find some of their other regular seed listings – but not Super Lemon Haze.
Even GHS support couldn’t give me a definitive answer. They were pretty sure SLH was only sold as feminized, and told me “only Arjan could say for sure,” but that he wasn’t currently reachable.
Then this thread popped up:
Almost like a sign.
And after reading it, I’ve come to the conclusion that it’s highly unlikely these are genuine regular Super Lemon Haze seeds from GHS.
So what are they?
Let’s find out together.
Germination
On May 27, I soaked 12 seeds in a 1% peroxide solution for 24 hours.
They’d been stored in the freezer, both by me and the previous owner.
After soaking, I placed them in EasyPlugs – and not long after, the first seedlings started breaking the surface.
I’m counting May 31 as Day 1 – at that point, 11 out of 12 had sprouted.
The last one never did, but I’m still more than happy with the result.
I’ve had similarly good germ rates before using this method – recently, 9 out of 10 Chocolate Rain seeds (also from around 2010) popped using the same approach. It works well for me.
Yesterday, I transplanted the 11 SLH plants from 0.1L to 0.7L pots.
I’m using a homemade soil mix – a peat-based base soil, enriched with 1/3 compost, worm castings, and biochar.
And yes – I’ll continue calling them “SLH” for now, since I don’t have a better label.
I’m genuinely curious to figure out what these plants really are.
The original plan was to make a repro of Super Lemon Haze and share it.
Whether or not that happens will depend entirely on what I’m actually growing.
Assuming SLH never existed as regular seeds, here are the two most likely possibilities in my mind:
- These are feminized SLH seeds from GHS
- These are regular seeds from a different GHS strain
Of course, it’s also possible that it’s something entirely different.
But for now, I consider those first two the most realistic scenarios.
I’m happy for anyone to join me on this little mystery grow.
If anything looks familiar, or if you have insight into GHS seed history – please chime in!
This is my first grow log on Overgrow, and I’m looking forward to your feedback, input, and questions.
In future updates, I’ll be sharing a bit more about myself and my setup.
For now, in three words: indoor – LED – organic.
But this intro post is already way too long again 
Happy growing & have a great Sunday!
