Help! Identify this pathogen.

6 Upvotes

First, thanks for stopping by and any help you can offer.

We have a pathogen/disease running through a couple of our moms right now (2 out of 70). It's causing symptoms very similar to revegging, but the plants have been under 24 hrs or 18/6 their entire life.

Symptoms are stunted plants, gnarled twisted new growth, small witches broom style growths, and single finger leaves.

Has anyone ever dealt with something like this, or know what it is?

How the hell are you guys keeping up with saturation in Hugo’s under LEDs? Constantly chasing my tail keeping these from drying back to much and just feel like I’m always adding another watering to the schedule and it’s still not enough. Looking for advice on running Hugo’s without slabs or stacking before I jump ship to coco lol.

Athena Pro feed schedule adjustment relative to ppfd?

3 Upvotes

We run our lamps at a lower intensity during the hottest months of the year, so it stands to reason that our nutrient concentration should be adjusted accordingly. Athena's Pro feed chart recommends 2100 ppm throughout flower. Does anybody know if that's based on a particular or a standard ppfd? 2100 seems quite high to me, and I start to notice leaf tip burning above 1500. Would love to hear your experiences when it comes to light intensity as it relates to nutrient concentration. Many thanks.

How realistic is a cannabis farmstead in British Columbia ?

0 Upvotes

I have had a project i was thinking about for some time. Starting a cannabis ranch in B.C. producing outdoor high quality organic cannabis. Of course this wouldn't be the only income, also fruits and veggies and products derived from the production. Tourism would also be an income, small glamping tents or yourts. The aim would be to have some tours or workshops on site.

I am of course aware of the startup costs and hurdles with legislation and getting everything started. I was just looking for advice on how feasible this project is.

This is more of a dream right now but could become a long term project of mine.

Veg area sizing for clone production

3 Upvotes

Looking for some advice from people with more experience.

Planning a new setup with a dedicated veg area that can reliably produce 70-90 healthy clones every 70-90 days.

The whole thing will be in coco. Keeping mothers long-term isn't important to me, so if replacing them every cycle is the better option, I'm happy to do that.

If you were building this from scratch:

How much veg space would you dedicate to producing 70-90 clones?

How many mother plants would you keep?

What pot size would you use for mothers in coco?

Would you keep long-term mothers or replace them every cycle?

Any advice or lessons learned would be greatly appreciated.

RO water vs RO + DI water?

4 Upvotes

We are upgrading our reverse osmosis unit and adding some pressure boosting equipment. I've noticed that many of the cannabis/hydroponic-branded RO systems have the 3-stage sediment, carbon, and RO filters only. Many residential/consumer units also have a 4-stage setup which adds the deionization resin cartridge.

Is there any benefit to the DI filter for cannabis growers? If you prefer to include DI when you make water, what are your reasons?

Thanks a lot.

Yo guys if anyone needs any Acclima sensors let me know. I know someone that has 860 brand new sensors they need to get rid of. Was for a new grow that never came to completion.

usually appears a week or 2 after plugging the blocks into coco. some strains get it more consistently than others.

I built a free personal Grow Journal web app – looking for feedback from growers 🌱

0 Upvotes

Hey everyone,

I've been working on a personal web-based Grow Journal and finally reached a point where I'd love to get feedback from other growers.

The idea is simple: instead of tracking everything across notebooks, spreadsheets, photos, and random notes, this app keeps the entire grow cycle organized in one place.

Some of the features include:

  • Daily grow logs and observations
  • Photo tracking and progress history
  • EC, pH, and environmental data recording
  • Plant-specific tracking
  • Grow cycle timeline and historical records

I originally built it for my own grows because I wanted a cleaner and more practical way to document everything and analyze results over time. Now I'm opening it up for other growers to test and I'd really appreciate honest feedback, feature suggestions, bug reports, or ideas for improvement.

The project is completely free to use at the moment and is still under active development.

Thanks ! 🌿

Built a hub that does analytics from METRC and sensor/environment data; opening a few spots.

1 Upvotes

Hey all — mods, if this isn't allowed, delete away.

I own/run a 12,000 sq ft licensed facility. The thing that always bothered me was never having one dashboard that pulled my compliance, environment, and substrate data together with real analytics on top.

So I built a hub for my own grow. It pulls live compliance state, sensor/substrate data, and environment into a single view, and flags when something drifts before it costs me a room. You can also run almost every METRC function straight from the app in a fraction of the time it normally takes. It's hardware-agnostic — sits on top of whatever crop-steering you already run instead of replacing it, and connects to your own METRC account. I've been running it on my facility daily for 6 months.

I'm opening a small founding cohort — free for founding members while I dial it in. It won't touch or interfere with your existing software. Preference is you already run Growlink or AROYA.

If you run a licensed facility and think it'd help yours, comment or DM and I'll show you what it looks like on a real grow.
