How to Grow Pea Shoots Indoors - Moral Fibres

A box of dried whole peas
A tub You can re-use a plastic food tray such as the kind you get when you buy tomatoes or grapes, a takeaway container, an old Tupperware tub, or a bowl. There's no need to buy anything new.
Cotton wool, kitchen roll, or crumpled newspaper
Water

First you need to work out how many peas you need. To do so place the dried peas into the empty tub of your choosing - ensuring the peas are densely packed in one layer only.
Empty the peas into a glass of water to soak overnight. Don't skip this step. We did this the first time around and the peas never came to anything.
The next day drain your peas and line your tub with a thin layer of damp cotton wool, kitchen roll or newspaper (perhaps a centimetre thick).
Add your peas to the container, spreading them across the container so they aren't all clumped in one spot.
Leave the tub on a sunny window ledge, and water when the cotton wool, kitchen roll or newspaper feels a bit dry. Be careful not to add too much water, as they will start to rot. As a rule, the cotton wool (or whatever you're using) should feel damp, not sodden. If you accidentally add too much water, drain it out.
Harvest once they are a few inches tall.
