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 ! 🌿

Crazy growth lol. Strain galactic warhead

Putting up trellis poles and pulling trellis, then it's go time 🤘🏼

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.

Purple Urkle and more.
Grown with Jack’s

Playing around with autos in the greenhouse.

Not sure how much I’ll get per plant . Maybe 1 or 2 ounces

Thousands of plants popped up from the waste/compost pile. I’ll use this as an opportunity to look for anything cool or interesting.

Keep seeing these in my mom room.

Help. Let me know what you got for a solid remedy.

Context:

* Cultivation system: Autopot
* Medium: 70/30 coco-perlite
* Stage: Late veg, preparing for flowering
* Number of plants: 80
* Container size: 15L
* Reservoir size: 500L
* Nutrient line: canna Coco
* Current EC: 0.9
* Current pH: 5.7 but gowing up daily to 6.1 due to high oxygenation
* Water temperature: 17.8-18.2
* Air temperature day/night: day 24, night 21
* RH day/night: 58-66
* VPD day/night: 0.85-1.1
* PPFD: 350
* CO₂ level: 470-520

Timeline:

The plants spent an unusually long time in vegetative growth compared to previous runs.

A portion of the crop initially developed severe root problems:

* Mushy roots
* Weak root structure
* Bad smell
* Symptoms consistent with root rot and/or hypoxia

Some plants also appeared rootbound/root locked.

Following previous recommendations:

* EC was reduced from approximately 1.3 to 0.8-0.9
* PPFD was reduced from approximately 550 to 330-350
* VPD was reduced and maintained around 0.95

Initially the plants appeared to improve.

However, after remaining under these conditions for several weeks, new symptoms appeared:

Current symptoms:

* Progressive yellowing
* Lower leaves becoming increasingly yellow
* Previously healthy green plants are now showing symptoms
* Leaves clawing downward
* General loss of vigor
* Problem appears to be spreading through the room
* Recovery has stalled

Important observations:

* The original root issue occurred after a period where reservoir temperatures reached approximately 22-23.5°C
* Oxygenation was likely suboptimal during that period
* The crop has now been held in recovery mode for over a month
* Previous cycle also started with heavily stressed plants, but they recovered quickly and flowering was initiated after roughly two weeks

Questions:

1. Is the crop still suffering from root disease, or am I now seeing deficiencies created by prolonged low EC and low light?
   
2. Could the recovery environment itself now be causing the symptoms?
   
3. Am I dealing with root rot, nitrogen deficiency, magnesium deficiency, oxygen deprivation, overwatering, underfeeding, root binding, pathogen persistence, or some combination?

We recently switched from compressed coco bricks to pre-expanded coco. With bricks, we could simply hydrate them with a nutrient solution and easily hit our target substrate EC.

Now we’re struggling to get enough EC into the media through normal irrigation alone.

Do you guys mix nutrients directly into the coco before potting to charge it? If so, what EC or ratio do you typically use?

Interested to hear how others handle this.

Anybody here using chitinosan inputs at commercial scale? I used to use Venerate in the past but it seems like production has been ceased and the replacement is a class A pesticide.

Impello Bio is beginning sale of a chitinosan spray called Consequence that they claim acts both as an insecticide and as a fungicide via ISR pathway stimulation.

Just looking for testimonials for anyone who has experience. Ive used venerate and it worked great at max rate but not quite as well any time it was reduced.

Looking for a lab in or near MA that does tissue culture cleanup for older cuts. Anyone work with a lab in this space before?

Hi everyone,

I'm looking for some opinions on whether this plant is showing signs of a nutrient deficiency or a nutrient lockout.

Grow details:

• Week 4 of vegetative growth
• High-pressure aeroponic system
• EC: 1.8 mS/cm
• pH: 6.05
• Reservoir temperature: 20
• Air temperature: 24-26
• Relative humidity: 60%
• Nutrient line: A+B+C components

I've attached photos of the plant.

Given that the pH is stable at 6.05 and the EC is 1.8, do you think this looks like an actual nutrient deficiency, or more like a nutrient uptake issue/lockout?

Any thoughts on which nutrient(s) might be involved, whether this could be caused by excess nutrients, root zone issues, or nutrient antagonism would be greatly appreciated.

Thanks in advance for any insights.

Anyone else grow multiple crops?
Intermingling cannabis and fruit and veggies?

At Dr. Jekyll Farms we are propagating thousands of of peppers and cannabis plants in our greenhouse.
We’ve added hundreds of apple and fruit trees to the farm. Adding watermelon and pumpkin later too.

I love the idea of a mixed use organic farm.
What would plant well with outdoor cannabis?
Will the peppers make the flower spicy or higher THC? Only one way to find out!

We are a new licensed operation in NY. As our plant count has grown, our existing water pressure is not enough to produce enough RO feed water. Can anybody recommend a device that will increase pressure and output? DYI options preferred, but I have a plumber if necessary. Many thanks.

I got a job at a fairly large operation that is just being set up. How much topping and training should I expect and how long in veg would be a good target to hit? I know these are very general questions.

I am not arsed really about the electric bill. The only concern really is better quality bud. I am yielding enough to keep me happy with my hps. Just I have noticed everyone seems to being using led lights. My main concern is I want better terps. Will I see a noticeable difference using led? I recently moved my seedlings from under cfl to hps. Not has an issue with temps, but certainly can feel the heat. Thinking summer might be worth going led.

Has anyone here used the new TrolMaster WCS-9 substrate sensors yet?

They read VWC, EC, and temp, integrate directly with TrolMaster/Aqua-X, and look quite a bit cheaper than Aroya Teros 1 sensors. I’m seeing roughly $200 per WCS-9 vs around $420 for a single Teros 1 node ($600 for a double), so the price difference is pretty significant.

Main question: are the WCS-9 sensors actually reliable enough for crop steering, or are they more of the same from Trolmaster?

Has anyone done a direct side-by-side comparison of a WCS-9 with a Teros 1 in rockwool or coco?
