I want to grow these and need advice;
1. where can I get the seeds?
2. I have an allotment with a small plastic grreen house. Is that a suitable place?
3. What kit would I need?

i want a reasonable supply ongoing during the year.
Thanks for any help.

Microgreens are any veg you fancy, but cut and eaten at baby leaf stage. You can use any seed, it doesn't have to be 'special'.
At this time of year I often sow seed left over from last year, in small seed trays of compost, on the kitchen windowledge. It's often mustard, cress, or brassicas, even peas left to grow a few inches tall, taste wonderful.

Give it a go...

Mostly, I see these as some sort of brassica/mustard at the "seed leaf" stage. Mum also mentioned peas, but remember that alfalfa and other seeds produce such greens.

If you have an old-timey seed store around, they may have larger packages of seeds for turnips, cabbage, etc. that would be much less expensive than buying packets.  Some such stores may even have bulk seed.

Don't forget that many of these greens can be harvested a little older to produce young greens that are beyond the seed leaves (very young true leaves). Beets and very young turnips are very good for these type of greens, the young leaves are wonderful in salads. Turnip greens from half-grown plants are amazing cooked greens.

I'd be curious to see what others grow as micro geens?

Thanks for the feedback. So any greens really. Just thinking would one need to sow them very dense like cress? If so how dense or even concentrated in an outside row?

And could be expensive unless as suggested by in bulk.

Denser sowing, yes.  Not like you would if you were actually trying to produce radishes or turnips, for example.  They are usually grown in a somewhat controlled environment (greenhouse or indoors, for example).  Sometimes the process is more like hydroponics than conventional gardening.

Try Googling "growing microgreens".  You will find a lot of good information.
