Sow pea seeds in pots following depth recommendation on seed packet. You can sow several in each pot and thin out weakest ones later or just sow one or two.
Water thoroughly and top up potting mix as needed.
Place under grow lights for 8 to 12 hours per day. Adjust times as needed. Top of plants should be just a few inches below lights.
Water consistently so potting mix does not dry out.
(Optional) As vines grow, add trellis and train vines up trellis.
Notes
Peas plants can be harvested as any time—first for the pea shoots and later for the peas and pods. Even if your plants never produce flowers (which is required for pod production), you can always harvest the tender shoots for salads, sandwiches, and stir fries. If you need to fertilize, we have a guide on fertilizers here.
