How about a tool to reduce cancellations and optimize deliveries?

Hi, I'm exploring ways to help producers solve some common problems I've found here in the community. I've seen many of you mention challenges such as order cancellations and difficulty lining up deliveries with clients.

I'm thinking of creating a simple tool for producers that could:

  1. Send automatic delivery reminders by email/SMS for customers to confirm or reschedule in advance.

  2. Manage reschedules directly through the tool, reducing confusion.

  3. pre-payment option with clear terms, including fair penalties for late cancellations.

The idea is to help prevent product losses and avoid wasting time. Would this kind of tool be useful to you?

What else could be added to make it more practical?

If you already use a system to solve this problem, how does it work and what is missing from it?

I really appreciate any feedback!

🥬 hydroponic plants 🌱

Decided to grow some lettuce and some orange hat tomatoes. I just started some sugar rush peach peppers in my other system.

Thoughts on what went wrong.

So i tried to make a harvest for thanksgiving and make a salad mix with broccoli radish and peas. the peas didn’t sprout in time that i needed and had to leave them behind. i had been bottom watering them without misting. soil was on a shallow 1020 at 2 qts per tray. the soil would be dark and damp every morning which helped mitigate mold growth from not misting after they began to sprout. i had some dead seeds mold after putting them to light despite a lack of germination (sprouts only took root but no shoots appeared on day 3). other than that the Broccoli and Radish were mostly ready by day 7. Germination was a bit uneven but overall had high success rate. Next Time I need to have the soil for the smaller varieties closer to the top since they’re so short.

Back to the Peas: Trays 1-4 from left to right before harvest. Yields:

  1. 4.55 oz about 98% germination
  2. 3.63 oz ~90% germination
  3. 4.52 oz ~80% germination
  4. 4.66 oz ~65% germination.
  • Waterdepth was at about 1/3 the depth of the tray, enough for the roots to drink and take hold in the bottom tray. This resulted in a more complete root structure than previous attempts.

-However i noticed that where there was less growth had practically dry soil. It’s possible there was uneven watering but I tried to account for that by leaning the trays towards the back (where there was apparent dryness). I need to check the leveling of the racks as they are in my living room. The hard wood floor may be warped from its age. -Another consideration: Uneven temperature - I turned on the boiler for the house on day 4 when I should’ve had it ready before i sowed everything. It’s currently set to 67F and the thermostat is on the second floor of the house where there’s a lot more sunlight. So overall it may be a bit colder down in my grow space. I may increase the temperature a bit to 72 but want to minimize the gas expense as the boiler is a bit older and I am only occupying 1 floor with my wife and cat. Would it be better to get a simple heater running periodically combined with a small thermostat / hydrometer?

I’m not as concerned with humidity as it gets pretty dry in the house. As long as I water regularly, the greens have always done relatively well, however bottom watering and misting may have been over doing it for my peas and sunflowers in the past.

TLDR;

  • I messed up my crop cycle for a thanksgiving harvest and my peas got left behind. Came back to them harvest ready at 10 days post sowing.

Yields were okay for personal use, but need to be higher for selling at scale. I need to fix my growing environment and seeding techniques.

This is a public service announcement

To my growers I wanted to give you a heads up. These were barrinas. Just when you think it’s fine to 10 lights on one switch don’t do it

Seed source for wood sorrel

Anyone know where to get this seed? It’s different than clover or the sorrel that TLM sells. Oxalis is the scientific name. Looks like clover except leaves are heart shaped, not rounded. AKA shamrock.

Soil after harvest

Hi everyone,

I just harvested broccoli microgreens and had a great time with the process. I used seed starter mix as my growing medium and all was well.

My question is: do you reuse that same medium again and again? I threw it into my worm composting bin, but if possible I would like to reuse it.

What do you all do? Any tips are appreciated.

Tips?

New to micro greens, these are my first: sugar ann peas. I have seeds for broccoli raab (I got the wrong kind) and arugula next. I haven’t been worried about fertilizer because I water from an aquarium. My other plants do very well with it. I have a fan blowing from below at an angle towards the shelf. Humidity is about 50% on a normal day. I know I can increase my seed density, this was just a quick start. Two on the left were not soaked and the one tray on the right was soaked for 8 hours, planted on Day 2 of the first trays. This is day 13/14 I think.

Looking for a bubbler

I bought some stainless steel mesh to grow on. I am using 1 inch deep 1020 trays with steel mesh placed on top. What’s a good bubbler system and will it integrate with my tray setup for steel mesh?

Sunflower Experiment

Sunflower: Experimenting with grow mediums and soak times

In order we have:

  • Light soil and seeds soaked for 12 hours
  • No Medium, just Mesh Tray and soaked for 12 hours
  • 416 Surgical Stainless Steel Mesh Reusable Grow Medium and soaked for 12 hours
  • Light Soil and Soaked for 3.5 hours (Planted 1 day ahead of others as well)

So far, the ProMix is winning but notably the soak times don’t need to be so long for these either.

Seed Source: True Leaf Market Soaked in diluted Hydrogen Peroxide solution

Watered with nutrient water only as well (OS 203)

I’m predicting the no soil group’s yield to be awfully low or to need an extra day or 2 in the lights. We will see how the true leaves look on targeted harvest day.

Anyone know what's going on here?

A few of our trays are only showing partial growth like this. My first though was there wasn't enough cococore in each tray or seeding was too dense. Any ideas?

What happened?

Ok, this is a new one for me.

Speckled Pea

The circle void of germination in the center of the tray. It was stacked and evenly weighted- this is after the three days (I don’t water during the germination period)

I have done many trays successfully and this is the first time seeing this

Has this happened to you? What’s going on here? 😂

Coriander advice

Hi guys, chasing some advice from coriander and sharing what I find from experimentation.

All 4 trays at the top have the same amount of seed, soaked for the same time and planted in the same way. 10 days germination, 1 day Blackout. The one on the left was germinated standalone with 1 ~300g paver as weight. The other 3 were stacked on top of eachother with another paver on top. Sort of like this basic diagram below

Stack 1 - tray 1<paver Stack 2 - tray 2<3<4<paver

How much weight does everyone germinate with? It seems crazy that so much difference can come from just that one factor

Flight Attendant Microgreens

Hello everyone! I am a flight attendant & I want to start growing microgreens, although I have a couple concerns:

Seeing that my job requires me not to be home for a stretch of 2-4 days at a time, would growing microgreens be possible?

If so, would an automatic watering system be worth it?

I currently live in Chicago but soon moving to Dallas

Height of racks for growing?

Going to use these racks for my first testing setup, just finished clearing off this one. What should be the distance between the lights and the shelves? Is there a certain height that is perfect? I have another 2 shelf levels as well I can add for more room. Thanks!

Need advice

First time growing. On 3rd day I put it near the window and on 4 day third part of radish looks wilted. I watered low tray with half cup of water and lightly sprayed on top. What I did wrong?

First (half-assed) attempt going better than expected! When should I harvest?

https://preview.redd.it/h1zfxmr8d92e1.jpg?width=768&format=pjpg&auto=webp&s=6cddfa5f89914eee11ea865b933c5519d5251016

I had seed starter trays and grow lights from my regular gardening, along with some potting soil, so I figured I'd get a basic microgreens seed mix from Amazon and give it a go to see what I learn. I wanted to test out proximity to the lights (the two trays on the left were started closer to the lights), as well as get a sense of watering volume and frequency. This is ~13 days in and I'm pleasantly surprised! I forget which is which (I assumed they'd fail), but these should be either lettuce greens, arugula, or broccoli IIRC.

  1. I read that I should harvest when the first set of true leaves has grown, it seems like that should be happening any day now -- any thoughts on how close to harvest these look?

  2. I kinda just spread the seeds based on what felt right. Are the ones on the left too full and the ones on the right about the right amount of sprouts?

Question: what most limits Microgreens profitability?

I'm developing a research grant proposal and in the past focused on ways to make substrate locally, and reduce electricity usage by investigating different LED's. I've worked with several different microgreen farmers that have indirectly answered this question, but curious to hear direct response opinions from here.
