I have to agree with Alexandeur Ross. Density of micros, specifically brassicas is going to cause dampening off and the yield will be very poor. Stacking trays helps the roots establish in good soil especially for Pea shoots and Sunflower shoots. Stacking, instead of covering the seeds with an additional layer of soil also gives a clean result to the micros for harvesting. Eliminating the need to wash them after harvest. You have the basics down but there are some nuances to getting the best results . Also using holes in the trays offers more even drainage in the tray. Placing a hole LESS tray underneath ensures better watering for those micros that prefer bottom watering as well. Microgreens are a great way to supplement winter veggie intake in any region, but most especially in areas where you can't grow food to it's maturity. The nutrition of microrgreens vs. mature plants is also a big consideration for those who are looking to eat 'cleaner' and with more vitamin and mineral intake. As a commercial grower of microgreens and other vegetables I'm always interested in learning and educating others. Thanks for the Video. Good luck with your micro endeavors.

I let my broccoli, cauliflower, & greens go to flower for the bees, then I can use the seeds for micro greens, since they are all cross-pollinated, mystery seeds.

Traditional germination trays are called 1020 trays as they are approximately 10"x20".

Thanks Luke. I bought a small green house with 4 shelves in on clearance at Biglots for $12.00 and 4 72 cell flats and put it in a spare bedroom and I will grow microgreens every winter from now on. our ancestors got out every spring to hunt for wild greens to eat. Spring tonic they called it. Now We can eat fresh greens all winter. Stephen.

Thanks to this video, my 5 year old daughter and I are growing 6 different types of microgreens. Excited!

If you consume what you grow in any way possible and you benefit from it, it’s far from being wasted. Thank you for being as informative as always!

Thx Luke! This and other vids inspired us to start an indoor garden of salad greens during the winter. Hopefully microgreens is next!

I like your method, once I get a short tray I'll be trying this. Thanks

Thank you for the video -- looking forward to how it all grows for you.

Luke, thanks for taking the time to make this video. We appreciate your willingness to share knowledge. In addition to the items you already mentioned, may I add that Buckwheat is another item that is good when grown as a microgreen. Thanks again. Please keep up the good work!

It's funny, it's the week after Christmas and I'm now noticing that as I'm starting my own microgreens you're talking about starting just after the craziness of Christmas... Great minds think alike! Now let's see how this turns out...

Microgreens are fantastic and its great to finally get past that winter solstice and now we can start planning next years garden. Hope the family is doing well Luke. Fantastic episode again, What plans do you have for next years garden mate? Tony

I received a lot of microgreens and sprouts supplies for Christmas. I already started them under grow lights indoors. I can't wait until they are ready to eat.

Great info! Thanks for sharing.

Nice video. Should you say "Grow Micro or go home." Lol. Thanks again for all you do for us.

Thanks for the information already learn something from you.

Just curious, how many seeds do you use in a 20 tray rotation? It's interesting the idea of rotating the crop through the cycle of the trays during the winter months. We usually plant in the raised beds out in the open, and utilize the seeds to cover a larger area. But interesting to plant close together to support the seedlings. Thanks for sharing!

"Oh no"!!!! I'm 4 days late to say.......... Merry Christmas Luke and your family!:) And a HAPPY NEW YEAR 2019

Well done!

I got a micro greens kit for Christmas! 😄

Would like to see more of the set up to grow them as well, you don't ever seem to show enough of that.

Whoa! If you plant 2 full sized trays every 2 days you are going to have more micros than 2 adults can possibly eat! I grow micros as a side business, many are only at their best for a few days to a week before they need to be cut and stored. Sunflowers for example get tough and fuzzy, and small ones get mould. As growing in such crowded conditions does increase the risk of mould, you might want to consider adding a fan for air circulation and either soaking your seeds or spray watering them with a weak solution of hydrogen peroxide.

Great information as usual :-)

We grow in 5"x 5" trays for sale as fresh produce. We charge $4.50 per tray and we sell out every weekend at farmers markets. The trays we use are very inexpensive and can be easily recycled by the buyer.

Very informative. The only thing thus far we have grown in flats is wheat grass fir juicing.

Hello there Luke I would like to say that I love your KZfaq channel very much. You have inspired me to start a garden next year. My garden will be the size of 57'X50' then. The other to KZfaq channels I watch is CaliKim29 and Roots and Refuge farm all day and every day now. And last thing I need to say is I love your latest videos you made then.

Luke what do you do with your old soil? I am in Phoenix and I am using it for the bottom part of my raised bed gardens.

enjoyed your video

I was waiting for this video. Last winter I tried sprouts. I was disappointed because the seed coats would be mixed among the sprouts like pieces of sand! When you said you were going to be growing micro greens, I thought "Hmmm. I'll wait till he starts and follow along!" With micro greens, maybe the seed coats will fall off and not be mixed in the harvested portion. So I will set a small tray of one of my sprout seeds right now.

Like others, I let many plants go to seed and use these seeds to grow microgreens in the winter. I've never purchased seeds specifically for microgreens🐝🌱

Luke, have u thought about not using any soil medium??? I'm going to try a small tray of some of the older remaining spinach seeds to see how it works out.

Thank you

Hey Luke, my husband and I are considering growing microgreens this winter because we live in Ohio and can't garden outside. The question that I have for you is that I have heard there is a danger with microgreens of salmonella and e.coli. Is that a real problem and what if anything do I need to do to prevent that.

Thank you for helping me see how using my excess seeds for microgreens is a wise decision! Are there some vegetables that are not safe to consume as microgreens?

If I get a mix for microgreens. Can I plant seeds individually and still receive normal sized plants?

You didnt mention "Lighting"...do you have a light on each shelf section?

Feel like microgreens aren't wasteful because it's high-density nutrition that you can put on just about any food in easily one tenth of time. Plus if you're growing your own seeds anyways you should be leaving a couple plants every season to get to seed, and most gardeners that do their own seeds have a surplus anyways

How often should I water them once grown out?

How close are the light s to the greens.. how many hours.,? Type of water, spray., sprinkle..?

For the flats you used, are they like disposable aluminum pans?

Hi all, did anyone catch what soil mix is being used? I heard him say Promix, but is there more in there?

Have you done a video on growing strawberries from seeds? can I purchase seeds off of your website but I'm not quite sure when to start them before the last frost so I can get strawberries for the next season

What's your soil mix?

Can i use a basket?

I really appreciate you describing what exactly a flat was.. that question drove me crazy just about a week ago, but got the basic idea after much wasted time. You helped me understand it much more clearly. Also, i feel that is extremely important the idea that you should not allow yourself to rely solely on grocery stores (& fast food for some) because they decide everything you have access to. I hope you understand the bigger problem here is Capitalism though. Thank you for all of your knowledge

If you wanna see the actual process, skip to 5:10

Are there any seeds that cant be used for microgreens?

One more question, I've been reading about microgreens and contamination. How can I avoid that growing them myself?

Can any1 tell me differance between microgreen seeds and a pack of the same type intended for growing to maturity, other than you get a shed load more seeds? Thanks

Also do the micro greens have to b juiced?? Or can u just eat them??

A flat.... approx. 25 X 50 CM (10X20 inches)?

Micro greens are way less wasteful than our seed store having to throw away seeds at the end of the year because they are too old to sell when the seeds are fine well most of them are fine

Eating corn is wasteful! You could grow an entire plant out of each kernel!!! Come on people, making microgreens is, practically speaking, consuming the seeds from last harvest as a consumable food after "boiling it" in dirt without heat for a while. It's no different then consuming corn instead of planting it. Just because you don't plant broccoli for it's seed to grow into microgreens but for it's florets, doesn't mean somebody else is wasteful for consuming their plant in this manner... Or you are wasteful for consuming the flowering head instead of letting it go to seed to produce a ton of other plants...

Where do I get a large amount of seeds at the cheapest cost?

Why broccoli?
