Whats the cause of the brown/grey spots
i had those spots before with peas. They did rot a few day later.
Now i have them again on daikon radish and im not sure if i still can eat them if grown. i think it might be bacteria.
Normaly i wash and disinfect this mini water system. but I bought new seeds this week and let them sit in water in a smaller bowl which was not desinfected for 24 hours (swapped water twice)
Construction of the v2 grow setup is now complete
I solved three issues with the previous setup. One was not enough space for two trays on each shelf slightly overlapped on the previous shelf, solved by having a slightly wider shelf. Two was a single light in the center causing bending during growth, solved by putting two on each shelf. Three was light bleed beneath the trays which was confusing the sprouts at early germination stage, many were going down towards the light bleeding from underneath, solved with mylar.
Downsides is I only have 4 shelves now instead of 5 previously for a total of 8 trays at a time which I think is perfectly fine because I'm not yet at the point of scaling. Also, the shelf takes up slightly more horizontal space because it's larger. The shelving unit has a fixed position for each shelf because of holes in the poles where each piece fits to hold each shelf. So ideally I could fit another shelf in it and lower the amout of space.
This shelf was only $33 so I'm willing to trade that off. The entire upgrade I estimate to be about $75. The trays I'm using now are slightly bigger as well so it was necessary, they didn't fit on the previous shelf at all so it's nearly worthless for this purpose, but I will use the old shelf for storage.
Does my radish have enough light?
Hello! I just started growing microgreens at home and wanted to experiment with light options. This tray had only blue+red lamp light.
Theese are radish (long one) and arugula.
I have see here that, if your plats dont have enough light they will be leggy and stems will be thin. Are those stems leggy and thin?
Arugula seems +- the same as I grew on a window sill.
I understand, that I would have been better, if I planted two batches of radish one in normal light and one in artificial, but it is what it is, and I need some help.
Another bountiful harvest turned into a salad

Black cumin failure - help 🙏🌱
I tried many times. Different approaches. I give up. Please share a secret of black cumin microgreens, if you have one!
First harvest
I started growing microgreens 10 days ago and will harvest this Monday 4/20. Quite a few true leaves are starting to show :)
This is 2Tbsp of about 15 different seed varieties in a 2-tier 10x7" steel container, coco coir liner for substrate, and a tiny bit of "Liqui-Dirt" fertilizer in the bottom tray. There are drainage holes in the top tray and a gap between trays that allows the liquid fertilizer to evaporate and penetrate the coco from the bottom with the roots in between.
I'm very happy with the results but it does seem a little crowded so I will use only 1Tbsp of seeds in the next batch as shown. I have 4 trays total rotating one tray every Monday for a steady supply of greens.
I'm planning on using hemp fiber mats instead of coconut fiber in the future, also in larger 12x9" steel trays for larger harvests.
I think this might be my new favorite hobby and any information or critiques are welcome!
What's the biggest scaling hurdle?
Hey all!
I remember the microgreens hype from a few years back (especially around Covid) where people were touting microgreens as an easy-peasy way to make gobs of money. I was tempted to try something and build a small business but limited myself to just growing occasionally for personal use.
I've recently "re-discovered" the concept and looked around to see the state of the industry. I'm not gonna lie, I'm thinking about giving it a try this time around. But I've seen the major companies which invested small fortunes go bankrupt and a lot of smaller cottage business discontinue after a few years. Why is that?
From what I've read online:
Competition and customer density
Expensive overhead (rent, electricity, seed, soil)
Time management (no real days off)
It's a niche, arguably luxury, niche product (lost revenue in economic downturns)
Freshness (Preservation and delivery issues)
It's primarily a sales job
For my specific situation:
I live in Western Queens in NYC so I'd have access to 4 boroughs with plenty of higher-end restaurants not to mention culinary schools, catering halls, bars, etc and from what I've seen, most producers are actually outside the city.
I have a large space I can use rent-free that would also allow me to also expand if I ever needed to (that I can't really use for anything else).
My days are already jam-packed with work so having two or three long days harvesting, packaging, and delivering sounds better than the non-stop that I'm doing now. Not to mention some things can also potentially be automated or semi-automated.
Nothing I can do about that.
Everything is nearby to each other but obviously one of the larger time-related, especially if you want to smooze and get to know your customers.
I've got some experience in sales so I have no issues hitting the strip and shameless soliciting customers.
Basically, I'm looking for someone to try to change my mind. I love my current job and make decent money but can't see myself doing it for another 20-25 years.
I want to build something for myself that is also scaleable and could grow substantially more if handled properly.
Got an ounce of purslane seeds a week or two ago, about to start my purslane microgreens grows!
I have a website too where I'll be documenting everything. Let me know if you're interested in the website name. I have my first grow on there.
Best medium for microgreens?
I’ve been using coco coir for my microgreens, but I didn’t realize that you’re supposed to wash it thoroughly before use, because it’s from coconut husks that are quite salty, which can affect the seeds. Some also suggest adding calcium/magnesium to it.
Would it just be simpler to use ‘seed starter’ mix in the future? What have you had good luck with? Thanks…
These speckled peas are the strongest growers I've experienced
These speckled pea microgreens are the crispiest I've eaten, compared to green peas, I think I like these more. They're more stalky, but the stalk is crunchy so crisp and the flavor is so good.
I've been doing this for about a month now, and I think I've found the process that's extremely lean while maximizing yield in my current setup. This has been awesome, because I'm about to construct the "v2" in the next week which I'll share with details.
Infinite glitch by cutting above the roots
is there any specific microgreen that makes an "infinite glitch" when it comes to it being cut above the roots?
