Looking at breeding differently

I've been thinking about breeding differently and I'd like the perspective of experienced breeders. Instead of treating a cultivar as one finished expression, I want to explore what happens when you deliberately separate its major expressions—terp profiles, structure, color, etc.—into their own selection paths, stabilize those directions, and then recombine them intentionally.

I'm especially interested in breeders who have worked a line for years and feel they've hit a wall. How do you approach a cultivar when you believe there's more genetic potential in it but the current selection path isn't revealing it?”

The Calm Before Flowering

Throwback to 2024! We filmed this a while back, and I thought it was too good to keep hidden. Take a look inside our veg room.

Bile Tolerant Gram Negative uptick recently ?

Lately , roughly since April/May we have noticed a considerable uptick in BTGN contamination of our dried flower. We have narrowed it down to our coco coir substrate . Has anyone else using Flora-Flex quick-fills noticed this as well ?

Drying.. IN A GREENHOUSE?!?

Autoflower for biomass! We cut and hang right on the wire and get 90% of the moisture out super effectively (CEA gh) and despite what everyone says, with UV protection the terpene and trichome degradation is minimal- we’ve ran 1,000s of pounds and tested this method, vs drying trays. The real change comes down to bucking styles.. whether you’re rupture cell walls and spill chlorophyll into the trichomes 😬. We don’t do this Peak summer but get away with it just fine in the other harvests. Running 65 days total, 63 in beds with a 2 day - highly-specific protocol for the germ sequence.

4 inch Rockwool Cubes from Start to Finish in macro7commercial growing

6 inch rockwool cubes is obviously the standard for commercial growers who want to grow with rockwool and without slabs. But honestly, I keep on asking myself why there aren't more people growing with 4 inch rockwool cubes from start to finish without slabs, smaller plants but higher plant count. Especially among those who plant with multi tier racks with height constraints. I never saw anyone doing this. For sure I can imagine that they will dry out much faster with only 1 litre of volume. But considering the fact that really huge plants are being grown in 6 inch rockwool cubes....

Anyone around who does it? Or did it?

organic (“living soil”) vs high frequency fertigation

I’m interested in what the communities perspectives are on organic growing methods vs high frequency fertigation mixed with scheduled biological applications (bacillus, trichoderma, myco)

Do you think growing in organic living soil produces a higher end product?

Other than the effort of dialing it in, I’m starting to see that HFF is the best style of growing.

What are your thoughts?

4x4 cubes drying out to fast.

Stacking 4x4 cubes on top of 6x6 cubes.

Once roots are penetrating the bottom of the 4x4’ when stacked on top of the 6x6’s the 4 x4’s seem to dry out from a 56-VWC down to a 10-12 VWC within 10-15 minutes. Bottom cubes are fully saturated, air flow is set to a minimum and room is currently at .8 VPD.

High Tech Glass greenhouse in the Mediterranean sunshine

Hi everyone,

Found my way here after seeing Nicholas Walker’s post on LinkedIn. Been lurking for a bit and figured I should introduce myself.

I’m Henrique, a commercial grower from Portugal. I run PREZE, a licensed medicinal facility where we’re currently growing three cultivars for the European market in around 2,400 m² of glass greenhouse.

We’re running Fluence RAPTR LEDs, hanging gutters, heating and a custom HVAC/dehumidification setup.
We’ve only been operational for about 6 months, so we’re still learning a lot and dialing things in, but I’m pretty happy with where the flower is heading.
This is one of our current batches — Funk Bomb, 22% THC, destined for the German medicinal market.

I mainly joined because there seem to be quite a few people here operating at commercial scale and dealing with the same problems we are.

We definitely don’t have everything figured out. Climate control, irrigation strategy, airflow, disease pressure, post-harvest, scaling SOPs… plenty of things have already given us headaches.
Happy to share what has worked, what hasn’t, some of the mistakes we’ve made, and compare notes with other growers here.
Looking forward to contributing.

Who else is running UCL?

Thick

Consistent....

It's a proud moment when you see a room where the environment, irrigation, and training all stayed on point from start to finish. 💪
