How to Grow Rocket Microgreens

Growing Rocket Microgreens are quick and easy. One thing you may notice when growing these microgreens are that the seeds are mucilaginous which means they can stick to the top tray if you are using one of those.

One thing about the Rocket is that it will put out roots quickly. This means that you will see spawn hundreds of little root hairs. You should not confuse them for being mold. While they look similar, you can identify root hairs by their even distribution and clustering around the taproot of your seedling.

You can benefit from adding some weight on a top tray during the blackout period. This will make the crop grow more even and speed up the germination process.

Culinary guiding

Mix your rocket microgreens with other salad leaves or add a handful of fresh arugula to an omelet or scramble, on top of a sandwich or wrap. Throw some on top of pasta or a pizza, just add at the last minute to retain the peppery flavor. 

You can also just add in a small amount of extra virgin olive oil and season with freshly ground black pepper and freshly grated Parmesan cheese. Simple but yet so tasty dish!
