Microgreens for the windowsill

I've been sorting out my old brassicas (that's seeds not an underwear typo). Even though brassica seeds are said to remain viable for 4 years, I know I'll never sow them - especially when I have "In Date" packets that probably won't be sown either!
Then I remembered this thread!!
Bumping it so I don't forget again.

I have masses of old brassica seeds too, so thanks for the reminder!

Anyone else growing or grown microgreens? We've been trying radish, broccoli and sunflower, growing them in those 8x13.5 inch trays which fit those flimsy 24-cell modules. The growing medium is just old pepper/tomato potting mix, sifted. I've used the same stuff 4 times now, just taking out most of the roots and levelling the surface before re-sowing. Radish and broccoli are incredibly easy, sunflowers a bit more finnicky. I just scatter the seed fairly evenly over the surface of the medium then put a tray over the top to block out light until they germinate, at which point they go on a window sill and are ready for harvest in a couple of days. 

Using the recommendations of this calculator - https://jscalc.io/calc/vqHxgaGIt3RncroW - per tray we're using 20g of radish/broccoli seed and 50g of sunflower seed. We're yielding 150-200g per tray. The seeds are from Premier Seeds Direct and it's working out at 40p/tray of radish, 55p/tray of broccoli and 67p/tray of sunflower. Buying the seed in larger packs would bring the price down by 10p or more per tray. I'm not exactly sure how much fresh microgreens sell for online, but it's got to be significantly more than £2 - £3.35 per kilo!

They're a good addition to salads, very nutritious, grow incredibly quickly and it doesn't matter about low light levels during winter because even though the seedlings get leggy, the stems are still very tender.

Here's one I started earlier.................and never did much with!! https://gardenandgossip.org/showthread.p...icrogreens

EDIT Both threads merged!

I’ve grown lots. I really like microgreens as garnish & running through salads. They add so much in the way of interest, colour, texture & flavour for something so small. I really enjoy growing them as well. You can easily spend a small fortune on  official microgreen seeds. I do occasionally buckle and try some of the more interesting ones. Generally I use any old brassica, lettuce, radish and herb seeds I have for microgreens.

There was a website about starting your own microgreens business. I looked at a few years ago it was very tempting to try. Can’t find the link now. Here’s someone making a decent profit out of it though and some ideas of varieties I’ve not tried yet   . https://www.finefoodspecialist.co.uk/gro...icro-herbs

This local business started during lockdown https://www.microacreswales.co.uk/ They seem to be thriving!

So the first shop is charging £166 per kilo   The Welsh place doesn't have weights listed but one of their photos suggests 30g per container, whether that is the small or medium I don't know, so somewhere in the range of £58 and £100 per kilo   Each one of my trays is apparently worth between £10 and £30

Thanks for the links, like you say SC there's a lot of seeds there that I'd not thought of using either it looks like less of my free seeds will be going to the charity shop.

I've just picked up a bucket load of spelt and sunflower seeds for sprouting. Also Broccoli and Alfalfa and another jar of unidentified seeds!!
My question to the panel is:-
Has anyone grown spelt, either in the garden or in a sprouter or in anything?

Can’t help. Never tried sprouting or growing. Mostly because I wouldn’t have a clue what to do with it.
Have you look at the seed database link for unknown seed ID? Or you just doing it the old fashioned way and see what grows   .
